Milwaukee Shockwave impact-duty driver bits are engineered to be more durable and better fitting. The optimized Shock Zone geometry is unique for each tip type to provide up to 30 times longer life and absorb 3 times more torque versus other impact bits. Absorbs peak torque and prevents breaking. Built to deliver extreme durability for the most demanding applications. Can be used in impact drivers or drill drivers. Custom machined tip prevents stripping and reduces wobble. Custom alloy 76 steel maximizes resistance to wear and shock. 135 deg split point for precision start, no walking. Titanium coated drill bits for longer life.
