DeWalt Impact Ready bits are made of a special steel designed to be ultra-durable. Each bit uses a black oxide process for greater wear resistance and strength. The tips can be used with impact tools more→rated for up to 2,000-in/lb. of torque.

The Milwaukee Shockwave 1 in. Impact Duty Torx T20 Bits are engineered to be the most durable, best fitting driver bits on the market. The Wear Guard Tip delivers increased wear resistance which prote more→cts the fit over the life of the bit. The Shockzone is optimized for each tip type and length of driver bit to absorb peak torque and prevent breaking. The Custom Alloy76 has a customized steel and heat treatment per tip type to extend the life of the driver bits, providing up to 50X life vs. competitive impact driver bits. The Milwaukee Shockwave driver bits are built to deliver extreme durability for the most demanding applications.

While most screw driving bits are simply compatible with impact drills and drivers, Irwin Impact Performance Series fastener drive bits are engineered for maximum durability and long life with impact more→drivers. These bits are forged rather than milled, so they fit fasteners more precisely, which reduces stripping and increases the life of the bit itself - Irwin's Impact Performance Series bits have three times longer life than traditional bits.
