Irwin Screwdriver Bit Set, Automotive, Impact Ready, -Piece ()

While most screw driving bits are simply compatible with impact drills and drivers, s Impact Performance Series fastener drive bits are engineered for maximum durability and long life with impact 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. s Impact Series bits have three times longer life than traditional bits. Manufactured with duty, cold forged, high grade steel, theyll withstand extremely high torque output. Plus, a black oxide finish resists corrosion and increases the life of the bit. This set contains 9 2-Inch Power bits that include #1, #2, and #3 bits, T10, T15, T20, T27, T30 and T40 Torn. There are 3 3-Inch Power Bits that include #1, #2 and #3 .
