Featuring a dual-flute design, the Milwaukee Step Bit provides jam-free performance along with greater speed and control. Optimized for cordless drills in the high speed setting, the bit works two times faster than standard bits, delivering up to 50% more holes per battery charge. The innovative Rapid Strike tip creates fast, accurate starts and generates less heat, while the optimized geometry and black oxide coating enable the bit to cut faster and produce less heat. Additional features include laser-engraved reference marks make it easy to stop on any hole size and a 3-flat secure grip shank to reduce bit slippage in the chuck.
