is harder than high-speed or cobalt steel, making it more wear resistant at
high speeds and providing longer tool life.
steel can be run at fast speeds and stays sharp longer
than high-speed steel tools, while offering resistance to heat and abrasion.
steel (HSS) offers
and shock resistance, and is compatible with a variety of materials.
steel offers performance that approaches that of carbide tools, but with the
toughness and shock resistance of high-speed steel.
