The Milwaukee Tool Shockwave Impact Duty Driver Bits utilize the company's Shockzone geometry to last up to 30 times longer and absorb three times more torque than other bits. The bits include a variety of tip sizes, lengths and kit configurations of Phillips, square, Torx, slotted, ECX and hex driver bits. The bits are made of Milwaukee's Custom Alloy 76 Steel and their Precise Fit Custom Machined Tip prevents stripping and reduces wobble, according to the company.
