High Speed Steel
High speed steel (HSS) is a form of tool steel; high speed steel bits are hard, and much more resistant to heat than high carbon steel.
They can be used to drill metal, hardwood, and most other materials at greater cutting speeds than carbon steel bits, and have largely
replaced carbon steels.
HSS Magnum™ Super Premium Drill Bits - Norseman™ Drill and Tool a drill with its thin web will penetrate the work hardening stainless fast enough to continually cut beneath the chip which is hardening from deformation. This means the drill is cutting softer steel. The cobalt drill, with its thick web, cannot be fed at a fast enough rate to cut beneath the area which is hardening. As a result the cobalt drill is continually drilling into hardened steel.
