Milwaukee Cobalt Red Helix Drill Bit Set, 23Pc

The 48-89-2338 Milwaukee Cobalt RED HELIX™ Drill Bit Set (23 Pc) is a heavy-duty drill bit kit built for fast drilling, long life, and stronger performance in hard metals. Using RED HELIX™ Technology—combining the QUAD EDGE™ Tip, VARIABLE HELIX™ flute, and a thicker tapered web—these cobalt bits stay sharp longer, clear chips quickly, and resist breakage under load. Designed for drill drivers, the 3-FLAT SECURE-GRIP™ shank helps prevent slipping in the chuck, and laser-etched sizing makes identification easy. The customizable accessory case is also designed for use in PACKOUT™.
