Fast-Cutting Carbide Ball End Mills. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material.

Most end mills are designed as up cut. The direction of the flute rake is the same as a drill bit which forces the chips along the flutes and out of the hole. What is a down cut end mill? A down cut end mill is when the spiral of the side flutes is raked forward. This forces the material being removed downward.
