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.

These Double-Fluted Step Drill Bits provide faster cutting and drilling than single flute bits. The easy-to-read step markings and targets save time when drilling holes. Thick 3/8-Inch hex shank provi more→des a firm, positive grip and won't spin out in the drill.

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.
