The Milwaukee step drill bits are made in the USA with global materials and give you best-in-class performance in impact drivers with the versatility to be used in drills. The 1⁄4” hex shank has an optimised SHOCKZONE body providing you with a more durable shank, reducing early shank breaks. A Titanium Aluminum Nitride (TiAlN) coating helps reduce heat build-up and deliver up to 5x longer life compared to a standard step drill bit. Additionally, Milwaukee’s step drill bits Rapid Strike tip and dual spiral flute produce 2x faster holes compared to a standard step drill bit.
