Irwin Impact Performance Series Torx T20 X 1-15/16 in. L Power Bit S2 Tool Steel 1 pk

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 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.
