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.

FLEXTORQ bits are engineered for durability. This latest generation from DEWALT redefines fitment and performance with overhauled tip geometries. The redesigned tip geometries for use with T25 size fa more→steners deliver 4X superior fit. Every FLEXTORQ bit features a FLEXTORQ Zone designed to absorb impact for longer life. Save time and find the right bit with new highly-visible laser-etched size. Each FLEXTORQ bit is IMPACT READY with a 1/4 inch hex shank for use in impact drivers and drills.

The Milwaukee Shockwave 2 in. Impact T15 Torx Bit is engineered to be the Most Durable, Best Fitting driver bit on the market. The Wear Guard Tip delivers increased wear resistance which protects the more→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.
