Features and Benefits

Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Oxide/Gold provides a polished finish and prevents chip building, galling and welding on a workpiece. It is commonly used in several applications on low carbons, stainless steel and iron based ferrous metals.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
