Features and Benefits
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Gold provides a polished finish on a cobalt or high speed steel tool. It is commonly used on aluminum alloy, titanium and plastic.
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
