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.
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.
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.
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.
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.
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.
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 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.
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.
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.
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.

Knowledge is your best defense against threading errors and tool damage, so let’s delve into the world of thread taps.
What Are Thread Taps?
Thread taps are tools in the machining industry that you can use to cut or form threads on the inside surface of holes, enabling you to insert screws or bolts. They come in various shapes and sizes, each designed for specific uses and materials. The process of using a tap to create threads is called tapping, an essential operation in manufacturing where threaded holes are necessary. For professionals in the machining field, understanding thread taps and their appropriate applications is crucial for ensuring accuracy, maintaining tool longevity, and preventing costly mistakes.
Hand Taps are the most commonly used types of thread taps, and they typically come in sets of three: the taper tap, second tap, and plug tap. Each tap has a specific purpose and use. With its longer taper, machinists use the taper tap initially to cut out most of the material and start the threading process.
Next in the threading process is the second tap. It has a shorter taper and cuts deeper into the material, providing more precise threads.
The plug tap, with the least taper, is the last one you’ll use to finish the threading process, ensuring the threads run the entire length of the hole.
You typically turn hand taps with a tap wrench, and you must use cutting fluid to reduce friction and prolong the life of the tap. Hand taps, being manual tools, allow greater control and are thus common in delicate operations where precision is paramount.
Master taps are specialized thread taps renowned for their high precision and quality. These taps calibrate other taps and gauges, hence their name. Their design matches an exacting standard, boasting impeccable accuracy in their thread profiles, which makes them perfect for verifying the correctness of other tools. Given their precision-oriented role, master taps often contain high-quality, durable materials to withstand wear and tear while maintaining their dimensional stability.
When using a master tap, you must ensure the tool in question matches the master tap’s thread pitch and profile. With careful handling and correct usage, master taps can serve as reliable benchmarks in a machinist’s toolbox for maintaining the accuracy and consistency of threading operations.
Machine taps are a broad category of thread taps specifically designed for use in powered machinery, such as drill presses and CNC machines. They’re best for large-volume production due to their speed and efficiency. Unlike hand taps that require manual operation, machines drive machine taps, significantly reducing the time and effort required to create threads.
Machine taps come in various styles, depending on the specific application, but they generally feature a more robust construction to withstand the higher stress of machine operation. Common types include spiral point taps, designed to push chips ahead of the cutting action, and spiral flute taps, which pull chips out of a hole.
When using machine taps, you must match the tap speed to the material you’re tapping and use the appropriate coolant for heat management. Machine taps offer machinists a rapid and efficient solution for high-volume threading tasks.
Gas taps are specialized taps designed with a unique feature: an internal channel that allows gas flow. This makes them essential in industries such as plumbing and heating systems. These taps often contain sturdy materials like brass to withstand high pressures and temperatures. Gas taps, named for their specific use rather than a threading mechanism, might employ any of the standard thread types depending on their application. The main element distinguishing them is their ability to control the flow of gas when coupled with a valve.
When using a gas tap, you need to ensure a seamless connection with no leaks, given the potential hazards associated with gas leaks. You also need to partake in regular maintenance to keep the valves in working condition. In essence, while serving a different purpose from those primarily meant for creating threads, gas taps still play a vital role in specific industrial applications.
As the name suggests, extension taps are for reaching areas inaccessible to standard taps due to their extended shank length. These taps are for threading deep holes or hard-to-reach places, a common requirement in automotive and aviation industries. The key distinguishing feature of an extension tap is its long, slender shank beyond the thread, which allows it to create threads deeper into a workpiece than a standard tap can reach.
When using an extension tap, you must align the tap correctly with the hole to avoid off-angle threading or damaging the tap. Additionally, due to the extended length and potential for flexing, we recommend applying steady, even pressure and using a suitable cutting fluid. Remember, you must take care when withdrawing the tap to avoid causing damage to the newly cut threads.
Machine Screw Taps
Machine screw taps are for threading holes for machine screws and bolts. These taps have fine threads and are for threading into metals, although they can also be for hard plastics or wood. The threading process involves the tap cutting into the material, creating a spiral groove that will accommodate a machine screw or bolt.
Machine screw taps typically contain high-speed steel (HSS) or solid carbide for strength and durability. Manufacturers often coat them with materials like titanium nitride to provide greater resistance to wear. They come in a variety of sizes, denoted by the specific machine screw size they must accommodate.
When using a machine screw tap, ensure that the pre-drilled hole is of the correct size for the intended screw or bolt. Also, use a suitable cutting fluid to minimize friction and heat buildup. This type of tap is a vital tool for any machinist working with machinery assembly or metal fabrication, providing a reliable method of creating accurate, finely-threaded holes for machine screws.
