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.

Specifically designed to handle the abuse that impact drivers dish out, the DeWalt DW2149 28-piece Screwdriving Bit Set consists of the most commonly used bits, made of a special steel that is designe more→d to be ultra-durable. Each bit uses a black oxide process for greater wear resistance and strength. The tips in the DW2149 set can be used with impact tools rated for up to 2,000 in. lb. of torque. Comes in a tough case to keep it organized and easy to transport.

DeWalt screwdriving bit tips are a perfect complement to your drill and driver and are designed to meet the demands of working professional contractors. Each bit is cut from shock-resistant tool steel more→and features an advanced hardening process that greatly reduces wear. Its snub-nose design fits perfectly into hex-socket adapters and the tips are precision ground to seat firmly into the screw head.
