The Milwaukee Shockwave Impact Duty driver bits are engineered to be the most durable, best fitting driver bits on the market. The optimized Shockzone geometry is unique for each tip type to provide u more→p to 30x longer life and absorbs 30x more torque vs. other impact bits. The Precise Fit Custom Machined Tip prevents stripping and reduces wobble while the Custom Alloy76 Steel and proprietary heat treat process maximizes resistance to wear and shock. Shockwave driver bits are built to deliver extreme durability for the most demanding applications.

The Milwaukee Shockwave 1 in. Slotted Impact 3/16 in. Bits are engineered to be the Most Durable, Best Fitting driver bits for the most demanding applications. The slotted bits feature Wear Guard Tip more→for increased wear resistance which protects the fit over the life of the bit. The impact driver bits have and optimized Shockzone for each tip type and length of driver bit to absorb peak torque and prevent breaking. The Custom Alloy76 is customized and heat treated per tip type to extend the life of the driver but by up to 50X vs. competitive impact driver bits.

DeWalt No. 2 square recess bit is crafted from shock-resistant steel for maximum durability and offers a hardened core for extra strength and long life. It is heat treated to resist breakage and wear.
