Features and Benefits

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.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
