Featuring a Dual-Flute design, the Milwaukee step bit provides greater speed and control than standard bits. Designed for use in cordless drills in the high speed setting, the rapid-strike tip creates fast, accurate starts and generates less heat, ensuring it stays sharper, longer. Utilizing optimized geometry along with a black Oxide coating, it cuts faster, reducing down time and increasing jobsite efficiency. Additional features include laser engraved reference marks, which make it easy to stop on any hole size, and 3-flat secure grip shanks to reduce bit slippage in the chuck.
