One selecting the best carbide and the mill the biggest problem people have is choosing the correct geometry and coding for their particular application. With a better understanding of what geometries encodings are designed to do makes the selection process significantly easier. Regardless of the specific application it will be used for the machining material, geometry, and coding will play the largest role in determining which carbide end mill is best suited for the application.

How Does a Carbide End Mill Compare to Other Options?

Before looking at specific carbide and mail characteristics it is important to quickly understand how it stacks up against other popular options. The two most popular options, not including the carbide end mill, it is high-speed steel and cobalt. High-speed steel is used for general purpose machining of both ferrous and nonferrous materials. Cobalt is designed specifically to cut difficult and abrasive materials. Carbide offers several advantages over high-speed steel and cobalt because of its extreme hardness and exceptional wear resistance. This allows carbide to be used at higher ...
... speeds and feeds without sacrificing performance. It also tends to create less deflection during the milling process which reduces or eliminates sidewall tapering.

Machining Material Considerations

When selecting a carbide end mill the machining material is not as important as when selecting high-speed steel or cobalt mills. Carbide offers numerous advantages, including versatility, which means it can easily handle a majority of ferrous and nonferrous materials with ease.

The Role of Geometry in Selecting a Carbide End Mill

The geometry of the carbide and mill plays a significant role in determining and mill performance. While there are a growing variety of exotic variations available, most carbide and bills can be broken down into high helix or low helix. The high and low terms refer to the helix angle of the end mill.

High helix carbide end mills are typically best suited for tougher, harder materials because they wear better although they are often used for aluminum as well. A high helix geometry provides more directed cutting forces on the vertical plane and less on the horizontal plane. This reduces tool deflection. As a result, chips are evacuated more quickly. Plus, the axial rake is more positive which makes it better suited for shearing and lower cutting forces.

Low helix carbide end mills typically perform better and soft materials and generate less chatter during the milling process. The low helix design also provides better results in terms of finishing. There are also a number of variable helix and mills which are designed to combine the benefits of high helix and low helix carbide and mills order to provide ideal results for specific milling purposes.

Does the Carbide End Mill Coating Matter?

The final consideration is the coding on the carbide and mill. Every coating provides a specific function. For example, some are designed to create a higher default surface speed to create a smoother finish. Coatings are often proprietary which means each one has a unique chemical composition. This makes it important to take a close look at the coding of any carbide end mill before deciding whether or not it will provide the best overall results for specific projects or more general applications.
