The Milwaukee SHOCKWAVE Impact Duty Bits are specially designed for use with Impact Drivers, but also deliver a full system solution for all drilling and fastening needs. SHOCKZONE Geometry reduces stress at the tip resulting in less tip breakages. The combination of the SHOCKZONE design and special heat treatment absorbs impacts and allows the bit to flex with spring like action. The compression forged tip provides the best screw head fit, reducing cam out and stripping, resulting in increased lifetime. Made from custom engineered steel, makes the bits more resistant to shock from impacting.1 x Pack of 10 Milwaukee SHOCKWAVE Impact Duty Bits PZ2 50mmPTDMIL430866
