Our metal-working range covers the high-speed steel (HSS) and cobalt drill bits that shops rely on for drilling steel, stainless and hard alloys. Cobalt bits keep their edge under the heat of tough metals, while HSS handles everyday drilling affordably.

Many feature a 135° split point that starts on contact without a center punch and won’t walk, plus parabolic flutes that clear chips fast for cooler, cleaner cutting.
