Features and Benefits
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
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 with a higher flute angle to remove chips more easily.
