Milwaukee Shockwave Impact Duty driver bits are to be the most long-lived, best accommodation driver bits on the market. The optimized Shock Zone geometry is for each tip type to provide up to 30X longer life and absorb 3X more torque versus different impact bits. The, custom formed tip prevents stripping and reduces coggle while the custom alloy 76 steel and branded heat treat process maximizes resistance to wear and shock. Shockwave driver bits are to deliver intense durability for the most demanding applications. >> Optimized Shock Zone geometry absorbs flush torque and prevents breaking >> Custom formed tip prevents stripping and reduces coggle >> Custom alloy 76 steel maximizes resistance to wear and shock >> Set 35 pieces .
