CNC Cutting Tools – All You Need to Know

When you purchase a CNC machine, you’ll most likely be asked to choose the different CNC cutting tools that are available. Here are a few things to consider: Drill bits, End mills, Threading taps, Fly cutters, and more. All of these tools will work differently, but have similar functions. Understanding each tool’s function will help you make the most informed decision. Also, don’t forget to keep a set of basic instructions handy.

Drill bits

Drill bits are used in various industrial applications. These bits are commonly available in different sizes and shapes and can be used in different ways. For example, there are insert drill bits, which are used for CNC applications. They feature ceramic inserts that act as cutting edges on the inside and outside of the bit. They also have a hardened cutting tip.

Most industrial drill bits fall into two general categories. One is the insert type, which is less expensive. It functions without the use of a grind wheel, reducing the time and expense of deburring the hole. The other is the twist drill, which requires the use of a tool grinder to be sharpened.

End mills

CNC cutting tools utilize end mills to create a circular profile on internal corners. A standard end mill has a radius of approximately half its diameter, but CNC machine operators may choose to use a larger diameter end mill to create larger circular profiles. CNC operators may also choose to use a dogbone corner that extends out from the cut area to create a perfect 90o corner.

End mills come in a variety of shapes and sizes, but there are two basic types available: high speed steel (HSS) and carbide (CCN). HSS is less expensive and is useful for older or less rigid machines or one-off production, while carbide is preferred for high-speed cutting and shorter cycle times.

Threading taps

There are several different types of threading taps for CNC cutting tools. Some types have every other tooth, while others are designed to be non-cutting. While hand taps are the most common, they are not suitable for CNC operations. Instead, you should invest in high-quality threading taps to ensure the best performance.

To ensure the best performance, you should lubricate your Taps properly. This will reduce friction and heat generated when cutting the part. Look for taps with lube vent grooves. This will prevent any tool mix-ups and ensure a more reliable production.

Fly cutters

CNC cutting tools have various functions. One such function is the fly cutter. The fly cutter is a cutting tool that can be used to finish the surface of a piece of metal. They are available in different diameters. The diameter of the fly cutter determines how much of the metal it can remove.


Fly cutters are also used to plane and machine the stock square. They should not be operated at too high a speed. This is because they need a slow, steady motion to produce the flattest surface possible. When using a fly cutter, it is important to position the cutting bit so that it is just past the edge of the surface before continuing. If the fly cutter does not reach this point, it will remove a slight amount of material from the back side of the cutting radius.
