Intersecting flutes create a fine finish, making these end mills good for operations requiring light stock removal, such as deburring, profiling, and finishing. Made of solid carbide, they’re harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills for the longest life and best finish on hard material. Since they have a fine pitch, they last longer than coarse-pitch end mills and produce smaller chips for better performance on harder metal, such as hardened steel and tool steel. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. All are center cutting, allowing plunge cuts into a surface.
