Features and Benefits
High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and nonferrous materials.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
