Features and Benefits
Vanadium high speed steel (HSSE) is made of high speed steel, carbon, vanadium carbide and other alloys to increase abrasive wear resistance and toughness. It is commonly used for general applications on stainless steels and high silicon aluminums.
WD1 is a multi-layer coating that is harder and more resistant to heat than TiAIN. It is commonly used on medium-to high-carbon steel and other difficult-to-machine materials. WD1 is a proprietary coating exclusive to OSG Tap and Die, Inc.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
