Features and Benefits

Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Uncoated tools do not feature supportive treatments on the cutting edge. They are are used at reduced speeds for general applications on nonferrous metals.
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
