IRWIN IWAF36SQ1 Power Bit Impact Performance Series Square Recess #1 S X 6 Inch L S2 Tool Steel Black Oxide - Pack of 5

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 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.
