Choosing the Right Cutting Fluid for Your Machining Process Read More
If you work with metal, you know just how critical cutting fluid is to the success of your machining processes. Cutting fluid can help improve your tool life, enhance surface finishes, and prevent workpiece damage. That’s why it’s crucial to choose the right cutting fluids for every specific project you take on. Learn your way around factors like materials and working conditions with this guide to choosing the right cutting fluid for your machining process.
Know That Materials Matter
Different cutting fluids are designed for specific materials, so before you select a cutting fluid, you need to determine the material of the workpiece you are cutting. Metals that are easy to work with, such as aluminum, cast iron, and copper, don’t need as much lubrication as harder metals like stainless steel or high-speed steel alloys.
Lubrication isn’t the only thing to consider, though. You also need to factor in the amount of debris the material creates during the cutting process. Metals like cast iron and copper alloys form a lot of metal chips, so they need a cutting fluid with better cleaning properties to prevent those chips from sticking to the workpiece or the cutting tools.
Consider the Machining Operations
Different machining operations require different cutting fluids. For instance, high-speed machining requires low-viscosity cutting fluid to reduce heat and prevent chip melting. Conversely, heavy-duty machining may require a high-viscosity cutting fluid that can handle extreme pressure and heat generated by the cutting tool. When choosing the right cutting fluid for your machining process, consider the air temperature, coolant pressure, and flow rate of your operations. This will help you find the option that offers the best balance of lubrication, cooling, and chip removal.
Understand the Environmental Impact
It is essential to consider the environmental impact when choosing a cutting fluid. Many cutting fluids contain hazardous chemicals that can cause environmental harm and pose a health risk to metalworkers if they aren’t handled properly. Make sure you have best practices for storage, handling, and disposal in place before you purchase these kinds of liquids. You can also choose synthetic or water-soluble cutting fluids as an alternative since they are free of harmful chemicals. Additionally, using cutting fluids with low VOC emissions can create a safer work environment for metalworkers while reducing the impact on the environment.

The Differences Between Reaming, Drilling, and Boring Read More
When it comes to creating holes or enlarging them, there are three key processes to consider—reaming, drilling, and boring. Each process is unique and requires specific tools and equipment to achieve the desired results. Knowing the differences between reaming, drilling, and boring will help you create the right cut in every project. Take a closer look at these three processes and explore the differences between them.
Drilling Creates a Hole
Drilling is the most common metalworking process of the three. It involves using a drill bit to create a hole in a piece of metal. The drill bit rotates at a high speed and presses into the workpiece, creating a circular hole. While a drill bit can create holes of various depths, it can’t create a hole wider than the drill bit itself. Drilling also creates a rough surface, which is why it’s often only the first stage of hole cutting.
Boring Enlarges a Hole
The biggest difference between reaming, drilling, and boring is that drilling creates a hole, while boring and reaming alter it. Once you drill a hole, you can then enlarge it by boring. Unlike drilling, boring uses a single-point cutting tool and requires an existing hole. A metalworker slowly feeds the boring bar into the workpiece, shaving off small amounts of metal with each pass. This increases the diameter of the hole and helps improve surface quality after drilling.
Reaming Creates a Smooth Finish
Reaming is a machining process that involves smoothing out a hole that you have already drilled or bored. Metalworkers use reamers to create holes with a high degree of accuracy and a smooth finish. Reaming also helps improve tolerance. Because the reaming process revolves around creating a high-quality finish, it involves minimal material removal and can’t substantially change the dimensions of the hole. However, you can use a reamer to change the shape of a hole, such as creating a tapered hole.
At TMT Toolbox, we have a vast selection of reamer drill bits for metal and other crucial metal-cutting tools. Explore our online inventory or talk to our team today to find the equipment you need to keep your workshop running smoothly.
3 Types of Abrasives Used in Grinding Wheels Read More

Learning your way around the different types of abrasives used in grinding wheels is essential for improving the efficiency and quality of your work. Read on to explore some of the most common abrasive types and their respective applications.
Aluminum Oxide
Aluminum oxide is the most common grinding wheel abrasive. It’s a versatile, cost-effective material that works with a wide variety of metals, including carbon, bronze, wrought iron, and alloy steel. Aluminum oxide is a tough and durable material with a sharp, fast cut. It’s a great standard option that delivers consistent quality and dependable performance for a variety of needs. That said, there are other abrasive options that offer a better cut rate and durability for more specialized needs.
Silicon Carbide
Silicon carbide is a synthetic material that is harder and more brittle than aluminum oxide. It is excellent for grinding non-ferrous metals, such as aluminum, copper, and bronze. Silicon carbide is also ideal for grinding non-metal materials like stone or glass. The biggest advantage of silicon carbide abrasives is how sharp they are. This makes them ideal for projects that require a fast cut rate. However, because silicon carbide is so brittle, it doesn’t have the durability of other abrasives and requires replacing more often.
Zirconia Alumina
If you need a tough, long-lasting abrasive, zirconia alumina is the way to go. Zirconia alumina consists of a blend of aluminum oxide and zirconium oxide. It is harder, tougher, and more durable than most other abrasives. It has outstanding wear resistance and works well in high temperatures and pressures. This abrasive’s extreme strength makes it ideal for working with steel or steel alloys.

From welding and cutting to bending and grinding, there are plenty of ways to injure yourself while working with metal. Your hands, in particular, are always at risk of injury. That’s why it’s vital to know the best practices for hand protection in the metalworking industry. Protect yourself so you can keep doing what you love with these handy safety tips.
Always Wear Gloves
The first and most important step in hand protection is wearing industrial safety gloves. Make sure that you wear gloves specifically designed for metalworking. Various types of gloves are available for different tasks, so choose the appropriate gloves based on the activity you are performing.
For example, if you’re working with hazardous chemicals, you need chemical-resistant gloves to protect your skin from spills and splashes. On the other hand, you need gloves that offer cut resistance without sacrificing your grip and dexterity when using cutting instruments. Always wear gloves that fit snugly to get the best level of comfort and protection possible.
Practice Good Ergonomics
Proper hand position is essential to prevent injuries. Position your hands correctly when using a tool or machine. Make sure you have proper grip strength by using tools with handles that fit your hands. Avoid awkward angles that put unnecessary strain on your wrists. Also, take breaks regularly and stretch your hands and wrists to prevent cramps, stiffness, and muscle fatigue.
Avoid Loose Clothing
Another important metalworking tip for protecting your hands is to avoid wearing loose clothing, especially baggy sleeves. While they are great for protecting your forearms, loose or baggy clothing can get caught in machinery or tools, leading to serious injuries. Always wear fitted clothing and pay special attention to your sleeves and cuffs to prevent any loose threads or clothing from getting caught.
Keep Your Hands Dry
Moisture can make your gloves less effective and increase the risk of injury. If you’re working in a humid environment, always keep a towel handy to dry your hands and gloves regularly. Sweaty hands can also make it difficult to grip tools, so dry your hands thoroughly before handling tools and materials.
Metal Lathe Turning Tips for Improved Accuracy Read More
To improve precision, finish, and overall quality of your parts, you need to learn how to make the most of every tool at your disposal. Learning your way around a lathe takes time, but there are plenty of tips you can use to master the skill and produce high-quality parts for every project you take on. Check out these metal lathe turning tips for improved accuracy in every piece you produce.
Use the Proper Coolant
Coolant helps your tools perform better so you can create smoother cuts without worrying about breakage, excess heat and friction, or other complications. However, you need to be careful about which kind of coolant you choose. Precision coolant is ideal for finishing applications. High-pressure coolant enables faster cutting speeds, making your process more efficient. Pay attention to the type of material you’re working with, the depth of your cut and feed, the outlet nozzle, and other factors to determine the right coolant type, pressure, and flow for your application.
Perfect Your Surface Finish
Achieving a perfect finish can be difficult with so many high-speed parts, but there are a few ways to make the process easier. As a general rule, a higher cutting speed results in a finer surface finish. If you’re dealing with a higher vibration tendency, use a smaller nose radius to keep your work smooth. It’s also important to factor in your insert geometry and insert grade, as these details influence the quality of your finish.
Invest in Your Turning Tools
Of course, one of the most straightforward yet crucial metal lathe turning tips for improved accuracy is to have the right metal turning tools at your disposal. Cheap, worn, or dull equipment will never achieve the best results possible, no matter how much skill you have.
Investing in your equipment means buying high-quality options from the start. It also means putting time and care into regular maintenance like sharpening and cleaning. The better shape your tools are in, the easier time you’ll have achieving clean, precise, high-quality results.
Drill Bit Materials: Understanding the Different Options Read More
Metal fabrication is a complex and intricate process that requires the use of the right tools and materials to achieve the desired result. One of the most critical pieces of equipment in this process is the drill bit. Drill bits come in various materials, each with their unique characteristics, making them ideal for specific applications.
In this blog, we will discuss the different types of drill bit materials and their uses in metal fabrication. By the end, you will have a thorough understanding of the various types of drill bit materials, enabling you to make an informed decision based on your specific metal fabrication needs.
Carbide Drill Bits
Carbide drill bits are known for their incredible strength and durability. This hardness allows the carbide bits to stay sharp for an extended period, making them an excellent choice for heavy-duty drilling tasks.
Carbide bits are perfect for machining materials with high tensile strength, such as stainless steel, cast iron, titanium, and other alloys. Their durability and resistance to wear make them suitable for high-speed and high-temperature drilling operations. However, the downside of carbide bits is that they can be brittle and prone to chipping, especially when subjected to sudden lateral forces.
High-Speed Cobalt Drill Bits
High-speed cobalt drill bits are an upgrade from the traditional high-speed steel bits (which we will discuss further in the next section). These bits are made from solid cobalt and are known for their exceptional hardness and heat resistance.
Compared to high-speed steel, high-speed cobalt drill bits provide improved performance in both drilling speed and lifespan. As a result, high-speed cobalt bits are ideal for drilling through hard and abrasive materials that high-speed steel bits can’t cut, such as stainless steel, hardened steel, and other heat-treated alloys. Though they can withstand greater heat than high-speed steel bits, it is still essential to use coolant to prevent premature degradation due to excessive heat.
High-Speed Steel Drill Bits
High-speed steel (HSS) drill bits are among the most common choices for metal fabrication due to their versatility and affordability. These bits are made from carbon steel combined with other elements like chrome, tungsten, and molybdenum. This alloy gives high-speed steel drill bits both hardness and resistance to high temperatures.
HSS bits are suitable for drilling through materials like mild steel, aluminum, brass, and copper. They can withstand high-speed drilling operations but may be prone to wear and dulling if used in highly abrasive materials or without proper cooling. In general, high-speed steel bits offer a solid balance between performance and cost for use in a wide range of metalworking applications.
Types of Drill Bit Coatings
Now that we have covered the primary material options for drill bits, let’s explore the different coating options available. Drill bit coatings give you more options when selecting the right drill bit for your metalworking application. Coatings and treatments help reduce friction, improve precision, or prevent premature wear and tear. Below are some of the most popular drill bit coating options available.
Black Oxide Coatings
Black oxide is a heat treatment option that many manufacturers apply to high-speed steel drill bits to enhance their performance. The coating process creates a thin, black layer of oxide on the surface of the bit. This oxide layer provides additional heat resistance and lubricity. It also enhances rust and corrosion resistance for the drill bit, significantly extending the lifespan of the tool. Black oxide high-speed steel bits are able to handle carbon steels and alloy steels, as well as softer metals like aluminum.
While black oxide coating can help improve the overall performance of high-speed steel bits, it does not drastically increase the hardness or heat resistance of the bit. It is an excellent option for cost-effective metal drilling but may not be sufficient for more difficult metals with higher heat and pressure requirements.
Diamond-Coated Drill Bits
Diamond’s incredible hardness and durability make it an ideal material for drill bit coatings. Diamond coatings consist of multiple layers of synthetic or natural diamond particles bonded together through a high-temperature, high-pressure process. This coating provides unparalleled hardness, wear resistance, and heat dissipation capabilities.
Diamond-coated drill bits excel in drilling through materials that are otherwise difficult to work with, such as glass, ceramics, tile, and reinforced composites. They maintain their sharpness, making them an exceptional choice for long-lasting performance. However, diamond coatings don’t work well with ferrous metals such as stainless steel.
Titanium-Coated Drill Bits
Titanium-coated drill bits are treated with a layer of titanium nitride. This gold-colored coating significantly improves the drill bit’s hardness, heat resistance, and overall lifespan compared to uncoated drill bits. Titanium coatings also increase the drill bit’s corrosion resistance and fatigue limit.
There are several types of titanium coatings, including standard titanium nitride, titanium aluminum nitride, and titanium carbon nitride. Titanium aluminum nitride and titanium carbon nitride enhance drill bit performance even further and create a longer-lasting drill bit than basic titanium nitride coatings.
Titanium-coated drill bits are incredibly versatile and suitable for use with a wide range of materials, including metal, wood, and plastic. They perform exceptionally well on materials like stainless steel, iron, and copper. Their durability and heat resistance make them ideal for drilling through tougher alloys and high tensile materials.
Titanium-coated drill bits are perfect for heavy-duty applications that require high precision and extended tool life. Furthermore, the light weight, faster RPM, and extreme endurance of titanium bits make them ideal for large-scale, repetitive manufacturing applications.
Finding the Right Drill Bit Material
By understanding the different types of drill bit materials available, you can determine which option is best suited for your metalworking application. As with any type of tool, the right drill bit can make all the difference in achieving a successful outcome.

Abrasive Selection Guide: Types of Metalworking Abrasives Read More
Anyone who regularly works with metal understands how important abrasives are to getting a final product that is actually useful. Whether you use them to cut sturdy materials down to size or sand down something to a clean finish, metalwork would be far more difficult without the use of a good abrasive. This abrasive selection guide will talk about the major types of metalworking abrasives and what they typically do.
Bonded Abrasive Discs
The most solid form of abrasives that get used very frequently is bonded abrasives, usually in the form of discs. They take a natural or synthetic abrasive mineral and fuse them together with binding and reinforcement agents to create a solid abrasive disc. These discs are very good at accurately cutting through solid metal materials, maintaining their shape and abrasive qualities even through some of the toughest metals available.
Coated Abrasives
Not quite as solid as the bonded abrasive, coated abrasives are also commonly found in disc form, though they can appear in other configurations. An abrasive material will be coated onto a stable backing and sealed in place with a high-strength resin to lock it in. While coated abrasives tend to be pretty strong, their major benefit over bonded abrasives is their higher degree of flexibility. This flexibility is more useful for grinding and removing material from a larger piece of metal.
Non-Woven Abrasives
For many in the trade, non-woven abrasives are usually referred to by a brand name—Scotch-Brite. Rather than having a solid backing like the coated abrasive, non-woven abrasives have a backing that is more fibrous and random. The abrasive material gets attached in the same way via resin, but the fibrous texture of non-woven abrasive discs is better for polishing and finishing, with some even adding grain patterns to the finished piece of metal.
Tips for Using Abrasives
With the types of metalworking abrasives defined, we can start thinking about the best ways to use them properly. These tips will help you make sure you get the most out of your abrasives.
- Using cheaper abrasives runs a higher risk of getting unclean cuts or unintentional shoddy finishes on your metal.
- Always test a new abrasive on something inconsequential before using it on something important to better understand its unique properties.
- Always go for the finest grit you can get away with for getting the job done. An abrasive that is too coarse will leave rougher finishes than you might want.
- Even the toughest abrasives don’t last forever. The longer you use an abrasive past its intended use, the more likely unexpected and undesired results will pop up.
To find the best cutting and grinding abrasives available, take a look through our selection at TMT Toolbox. We offer plenty of abrasive options suited to your individual needs.
The Benefits of Investing in Premium Machinist Tools Read More
Any machinist or machine shop knows that you are only ever as good as the tools you use to create products. You can have all the experience in the world, but if you don’t have the right tools to get the job done, you are already stuck. It’s no secret that machinist tools aren’t cheap and need to withstand heavy use over time; thus, the decision to rely on cheaper tools is almost always the wrong one.
As a supplier of high-quality machine tools, we know what happens to those who try and rely on lower quality, cheaply made machinist tools. Most of the time, the buyer will wish they had chosen the premium models instead because of how much more reliable and efficient they are.
While it can be intimidating to look at and think about paying the prices for these machines, we want to go over the benefits of investing in premium machinist tools so you can see what you’re really paying for. It is very much a long-term investment, but you’ll be glad you did later down the road.
Reliable Quality
There is no beating around the bush here. When you pay for premium machinist tools, you get premium results. In most industries that use these machines, even minuscule imperfections can be a serious detriment, so having a tool that is incredibly precise and accurate is key. Beyond high-quality results, you also rest easier knowing that these results are reliable in the long term. Your premium machine won’t start to lose its quality after only a few uses.
Reproducible Results
Getting those high-quality results is crucial to your success, but that doesn’t mean much if you can’t produce enough to meet orders or quotas. Your results need to be more than just good; they need to be consistently good time and time again. Premium machinist tools that you invest in don’t just give you great results, but they do so over and over again without any mistakes that might hurt your credibility.
Longer Life Spans
We all know the pain of buying something new, only to watch it break or fail far sooner than we would like. This is a risk you run every time you buy a tool with only cost in mind. While you can certainly make some machinist tools cheaply, there’s no guarantee that they will last long enough to remain useful for a significant period of time. If you don’t want to constantly spend money replacing broken tools, make the investment in quality now rather than later.
More Safety Features
Even with all the training in the world and a lifetime’s worth of experience, mistakes can happen. Unfortunately, in these kinds of industries, even small mistakes can cost you far more than you would like to pay. The safety features of these tools help filter out the chance that human error will cause a terrible accident. Higher-quality machinist tools are made with humans in mind, incorporating state-of-the-art safety features that can make a terrible accident into something far less tragic.
High Degree of Specialization
A trend in cheaper products across a lot of industries is making multi-use tools. While this concept seems useful on paper, a tool that gets designed to be able to do everything can almost never do all of them well. Investing in premium machinist tools means you will receive a tool specifically designed to do what you need it to, rather than something that tacked on that functionality later as an afterthought. This specialization ensures a much higher quality end product than a jack-of-all-trades tool.
Depending on your specific industry, you might need your machines running as often as possible for as long as they can go without stopping. Uptime can be a huge concern for machinists, especially if they need to pump out a lot of product very quickly. One of the benefits of investing in premium machinist tools is they usually have significantly more uptime capabilities than their cheaper alternatives. More uptime means less time wasted standing around waiting for something to happen.
Positioned for Growth
If you’re just getting started and don’t have a ton of funding, it is tempting to choose a cheaper option for your tools to save money. However, if you plan on growing your business and you know a specific tool will be integral to that process, you owe it to yourself to invest in your future growth. Higher quality machinist tools will last you much longer, as they can better handle an increase in production quantity as your business grows.
Efficient Energy Usage
Any machine shop around has a much higher demand for energy than the average person. Therefore, energy costs are another huge expense that machine shops have to constantly think about. For most machine tools, higher quality products will be able to more efficiently use energy to do their work compared to cheaper versions. Even a slight increase in energy efficiency can drastically reduce energy costs over time.
Faster Support and Customer Service
No machine tool is completely perfect, and you might run into a situation where you need to ask the manufacturer for help with setup or troubleshooting. You’ll find that manufacturers dedicated to producing high-quality tools will offer much more comprehensive customer services and support. If you need a problem dealt with as soon as possible and can’t suffer delays, you will be glad you chose a manufacturer that prioritizes customer service and quality over everything else.
Useful Warranties
Warranties are a crucial part of any expensive machinist tool. Familiarizing yourself with the warranties afforded to any piece of equipment will make it easier to choose something you can rely on. Lower-quality tools may not offer warranties of any kind because they know that their equipment won’t last a long time. If a tool comes with a warranty, it’s a good indication that the manufacturer puts a lot of stock in its level of quality.
If you need a machine tool supplier that will make it easy to get the premium equipment you need, TMT Toolbox has what you are looking for. We are always glad to help our customers find the tools that will match their needs the best and last well into the future.
Precision Measurement Tools: Essential for Any Machinist Read More
Any experienced machinist will tell you that precision in measurements is one of the most important things to focus on. There is very little wiggle room when it comes to measuring any machine’s parts unless you want a catastrophic failure to deal with later on. To combat this from happening, machinists need these precision measurement tools that they can trust to provide essential and accurate measurements in any situation.
Digital Calipers
Arguably just as important as a construction worker’s hammer or an accountant’s calculator, every machinist needs calipers that provide precise measurements down to the smallest fraction of a millimeter. Digital calipers will be a machinist’s best friend as they allow them to see a more accurate measurement of what the caliper is around that can’t be seen with the naked human eye.
Digital Micrometer
For machinists that focus on much smaller projects, sometimes a bog standard caliper won’t be able to get the job done in such tight spaces. That’s where a digital micrometer comes in handy. It’s an essential precision measurement tool that machinists use to measure extremely small parts in equally small increments. With measurements this small, you can’t trust just your eyes to see what’s going on, which makes a micrometer absolutely crucial to have in your toolbox.
Gauge Pins and Blocks
Finding gauge pins or gauge blocks that you can trust is all about getting them from reputable vendors such as TMT Toolbox. Both gauge pins and gauge blocks are used to accurately measure machined holes, where pins are for circular holes and blocks are for holes with hard angles. Any good machinist will have a set of gauge pins and blocks in plenty of sizes to accurately measure any machined hole with ease.
Machinist’s Squares and Protractors
Straight lines and precise angles are another crucial factor in creating machines that work as they should. Precision steel squares make sure that you can always get a straight line, but also provide easy reference for getting a perfect right angle. On the other hand, a machinist’s protractor allows you to measure out and model the exact degree of angle that you need. Whether you’re measuring for a cut or ensuring that an angle is perfect, you will need these tools to succeed.
No matter what kind of precision measurement tools you need, TMT Toolbox is the place you can trust to find ones that won’t let you down. We focus on providing quality and durability for all the tools we offer so you can focus on the job at hand and not on the tool in your hand.
Top 5 Safety Tips for Working With Machinist Tools Read More
Machine shops might seem like dangerous places to work for those outside the industry, but danger only really pops up when machinists don’t follow safety protocols the way they should. The tools machinists use are inherently dangerous, given what they can do to materials much stronger than the human body. These are the most important safety tips for working with machinist tools that you need to follow diligently to keep everyone safe.
Extensively Train Employees on All Machines
Knowledge is the best defense to protect yourself against these tools. Even if one person doesn’t use a specific tool very often, they should still know how it works and what could go wrong with it. Everyone in the machine shop should be aware of how each tool functions as well as what needs to happen with that particular tool in an emergency situation to reduce potential harm.
Never Forego Personal Protection Equipment
Personal protection equipment cannot be overlooked, no matter how long you’ve been working with a specific tool. Certain PPE, such as masks or respirators, are essential for keeping yourself healthy in the long term. Other equipment, such as industrial work gloves and safety goggles, can protect a machinist in a worst-case scenario situation. PPE is more than a precaution for working with these tools—it’s a requirement.
Keep Tools Well Maintained
Many machine shop tools need regular maintenance to ensure they work as intended and present as little risk for a malfunction as possible. In the same way that a dull kitchen knife is actually more dangerous than a sharp one, machining tools that have been working for a long time are at a greater risk for an accident or malfunction than one that’s been well maintained.
Never Force a Stalled Machine
Machine shop tools are designed to do as much of the work for the machinist as possible. There should never be a situation where you have to use force in order to get a machine working again, even if it seems to have stalled or gotten stuck. Using force to fix an issue like this is a recipe for disaster. You’re much better off shutting the machine down and addressing the issue before you harm yourself or damage the machine.
Always Inspect Machines Before Use
Even if you’re the safest machinist known to man, there’s no guarantee that everyone around you follows the same safety protocols. Before you begin working with any machine, give it a thorough once-over to make sure it was shut down correctly and that there are no ongoing hazards. Inspecting a machine before use will benefit everybody involved in its use and doesn’t take very long at all.
These safety tips should make working with machinist tools a much less hazardous experience for you and anyone who comes after you. A little bit of precaution can go a long way toward creating a safer working environment.
5 Common Mistakes To Avoid When Using Metal Cutting Tools Read More

Not Wearing Protective Gear
Safety should always come first when working with metal cutting tools. It is important to wear safety goggles and gloves while working with these tools, as they can cause sparks and flying debris during operation. Even if you’ve used your machine reamer thousands of times, you should never forego proper safety gear. Also, make sure you have the proper safety gear for the specific job you’re doing; for example, you should wear hearing protection when using loud power tools for extended periods of time.
Not Setting Up Properly
Before using a metal cutting tool, it’s important that you take the time to set up your space correctly. This includes making sure the tool is securely mounted on a stable surface before turning it on, as well as ensuring that all guards and shields are in place and functioning correctly before beginning work. Avoid presuming that a tool is ready to go without an inspection, as someone may have changed things without you knowing.
Choosing the Wrong Tool for the Job
Different types of metal require different types of tools for successful cuts. Make sure you understand what type of tool will get the job done most efficiently before beginning work. Even if there are other tools that might work, you don’t want to end up wasting time or resources due to choosing a less efficient tool.
Not Cleaning Up After Cutting
Metal shavings can be dangerous if left lying around after a job is complete. Not only can they cause slips or falls, but they can also interfere with other projects being worked on nearby. Therefore, it’s important to clean up any debris created by your cutting tool immediately after completing a job so that your workspace remains safe and tidy at all times.
Working Without a Plan
A common mistake beginners make when using metal cutting tools is assuming they know the most efficient way forward without developing any kind of plan. This often leads to wasted materials or inaccurate cuts due to inadequate. Instead of relying on improvisation during production, make sure you have a clear idea of the steps you need to take ahead of time so that everything goes smoothly once you begin work on site or in the shop.
Following these tips will save time and money by avoiding costly errors. TMT Toolbox has all the supplies you need for your shop, whether it’s a new machine or personal protective equipment you can rely on.
Metal Cutting 101: An Introduction to the Basics Read More
It’s hard to even imagine human civilization developing without the advancements that came as a result of using metal in our everyday lives. Manipulating metal to create tools and inventions is one of the key aspects that led humanity to where it is today. Over time, we have developed a plethora of ways to change the characteristics of metal to suit our needs, whatever they may be. Metal cutting, and eventually machining, is a huge part of this.
By definition, metal cutting is the process of using tools to shape or cut metal into various desired shapes. We use this process in a variety of industries, from automotive manufacturing to furniture making and far beyond. If you’re new to this or just want a refresher course, we’ll give you an introduction to the basics of metal cutting and its many intricacies.
Types of Metal Cutting Tools
When it comes to metal cutting, there are three main tools that you need to know about: saws, drills, and grinders. Each tool is suited for different types of jobs, so it’s important to know which tool is best for the job at hand. These categories are very large umbrellas, and they include everything from extremely basic hand tools to modern machines that perform these processes quickly and accurately.
Saws
Saws are used for cutting straight lines into steel or other metals. They come in two varieties—hand saws and band saws—and each has its own advantages and disadvantages. Hand saws are great for small projects where precision is not necessary, while band saws are more precise and can handle larger pieces of metal. Band saws may produce better results, but they also require more training to use properly.
Drills
Drills are used for putting precise holes into metal. They work by spinning a drill bit at high speeds while pushing it against a metal surface. This creates small chips that eventually wear away the surface of the metal until a hole is formed. Drills come in a variety of sizes and styles depending on your needs. Electric drills are typically used when working with hard metals such as steel, while pneumatic (air) drills are better suited for softer metals such as aluminum or brass.
Grinders
Grinders are used for grinding down surfaces or edges of metal pieces. They use a spinning wheel covered in an abrasive material to quickly remove excess material from the surface of the piece being worked on. Grinders come in two varieties—angle grinders (which have wheels mounted on an angle) and straight grinders (which have wheels mounted perpendicular to the handle). Angle grinders are better at reaching tight spaces. Straight grinders offer greater control over your workpiece due to their lack of angles. The effectiveness of these grinders depends heavily on the skill of the operator.
Metal Cutting Materials
The type of material being cut will determine which type of blade or attachment you should use with each tool. For example, aluminum needs a specialized blade because it tends to dull regular steel blades quickly due to its soft nature. The best way to determine which type of material you should use is by understanding each material’s unique properties or by consulting with an experienced professional who knows what types of materials would be best suited for your project.
The Main Types of Metal Cutting
There are several types of metal-cutting methods, and some are more common than others. Each type has its own unique benefits and drawbacks, depending on the application. Let’s take a look at a few of the methods that we use most often.
Sawing
Sawing is perhaps the most common type of metal cutting because it is quick, accurate, and easily repeatable. Although the term sawing evokes an image of a typical hand saw moving back and forth, machine sawing actually comes in a variety of different shapes. There are many types of saws used for cutting metal, including hacksaw blades, band saws, jigsaws, circular saws, and reciprocating saws. The tool you choose will depend on the thickness and shape of your material as well as your experience level with using simpler tools. Modern saws take a lot of the work out of the cutting process, but they still require the right knowledge to use safely.
Shearing
Shearing involves using two blades that come together like scissors to cut through material. This technique is much faster than sawing but can cause distortion in thin materials due to its high speed. Shearing is typically used to cut sheet metal or trim straight edges from larger pieces such as pipes or beams.
Heat Cutting
Far more common nowadays is using applied heat in different forms to cut metal extremely precisely. We see this most often in processes like laser cutting and plasma cutting. While they aren’t perfect cutting methods, as they can cause distortion and damage due to the extreme heat, careful use of these processes can make a huge difference in the quality of the finished product.
Grinding
As we previously mentioned, grinding involves using an abrasive wheel to wear away material until it reaches the desired shape or size. This process is much faster than manual chiseling but also produces more heat, which can cause damage to softer metals if not properly controlled or cooled during use. It is also important when grinding that you use safety equipment such as eye protection. Sparks from grinding can fly off in any direction during use, which can cause serious injury if you do not protect yourself against them ahead of time.
Safety Practices and Precautions
Speaking of safety equipment and precautions, metal cutting safety should always be your number one priority. This means wearing protective gear such as safety glasses, gloves, and earmuffs at all times when operating any type of power tool. No matter how experienced you are or how familiar you are with a tool, a single slip-up could cause a disaster if you don’t have the right protective equipment.
It’s also important to keep your work area clean and free from debris that could cause accidents or injuries. Additionally, make sure you use the appropriate type of blade or attachment for the job at hand in order to reduce the risk of injury or damage to your equipment.
Because this is just an introduction to the basics of metal cutting, there is quite a lot we still haven’t covered. Here at TMT Toolbox, we offer high-quality metal cutting tools to our customers and the knowledge that we’ve accumulated over many years in the industry.
