High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and nonferrous materials.

AM200 coating allows for the best performance in minimum quantity lubricant applications. It offers excellent wear characteristics, a high heat threshold and ideal for most high penetration drilling applications. AM200 is a proprietary coating exclusive to Allied Machine.

Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.
