Hard metals demand a bit that stays sharp, and this Milwaukee RED HELIX 15-piece cobalt set is engineered for durability in stainless steel, cast iron, and black pipe. A quad edge tip delivers a precision start, a variable helix flute runs from 35 degrees to 15 degrees for rapid chip removal, and a thicker tapered web adds strength. Cobalt provides up to 15x the life of black oxide bits.
