Understanding the Different Types of End Mills
End mills are essential tools for any metalworker, and selecting the right type can make all the difference in achieving the perfect cut. With so many different types of end mills on the market, choosing the right one can be overwhelming. Understanding how the different shapes, sizes, and configurations serve the unique requirements of your project allows you to select the perfect tool for the job every time. Learn about some of the most common end mills to use in your machine shop with this guide to understanding the different types of end mills and their applications.
Square End Mills
Square end mills have a straight cutting edge that creates a sharp, 90-degree profile when milling. As a result, the square end mill is perfect for cutting flat-bottomed grooves and slots. These end mills are also great for slotting, plunging, and profiling operations. The square end mill is available in a variety of sizes and flutes, making it a versatile and appropriate option for a wide range of machining applications.
Roughing End Mills
Roughing end mills are specially designed to quickly remove a significant amount of material from a workpiece. They have a coarse tooth design on the surface that helps break chips and reduces heat buildup. The efficiency of roughing mills makes them ideal for working with large surface areas.
Ball Nose End Mills
Ball nose end mills have a round end that creates a smoother surface finish. These mills are perfect for contour milling, but they also work well for pocketing and shallow slotting. The radial end of the mill is ideal for shaping and carving irregular shapes, curves, and angles on a workpiece. The ball nose end mills have a shallow depth of cut and help reduce chipping while milling. Furthermore, the smooth surface finish helps increase efficiency by speeding up your finishing process on every workpiece.
