Red Helix Cobalt Drill Bits

Like their predecessors, Milwaukee Tool’s (Brookfield, WI) Red Helix Cobalt Drill Bits limit heat buildup with an aggressive 35-degree helix angle that varies along the flute to end at 15 degrees. Two additional features enable the new bits to provide up to 15 times the service life of black oxide drill bits: A 135-degree split point quad tip that delivers a precision start and prevents walking for fast, accurate holes in hard metal; and an enhanced tapered web that increases flute durability by strengthening the core.

Next-generation Red Helix Cobalt Drill Bits are available in sizes ranging from 1/16 in to ½ in.
