Features and Benefits
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Nitrided land increases durability on the raised spiral areas at the end of the drill bit. It is commonly used on aluminum with a high silicon content, brass, cast iron, plastics and mild steels
Parabolic flutes are constructed with a wider flute shape for increased chip flow.
