The Milwaukee Hex Shank Drill Bit 5/16 in. is engineered for heavy-duty, precision drilling in wood, metal and plastics. Its alloy-steel body features a durable titanium coating that delivers up to 3× the life of standard black-oxide bits. The 135° split-point tip provides a clean, fast, no-walk start, while the Red Helix design and variable 35°–15° flute angle ensure rapid chip evacuation, reducing heat buildup and extending bit sharpness.

Built for impact drivers and quick-change chucks, this bit’s 1/4 in. hex shank offers secure retention under high torque. At 4-3/8 in. overall length with a 2-39/64 in. flute length, it strikes the ideal balance of reach and control for a variety of jobsite applications.
