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

AM300 coating allows for the best performance in minimum quantity lubricant applications. It offers excellent wear characteristics and is similar to AM200 coating, but with improved wear resistance at higher penetration rates. Ideal for most high penetration drilling applications. AM300 is a proprietary coating exclusive to Allied Machine.
