Irwin Industrial Tools 1866983 Impact Performance Series Insert Set (10 Piece) (1866983)

Forged rather than milled, to fit fasteners more precisely, reduce stripping, and increase bit life. Forged from high-grade S2 steel. Black oxide finish resists corrosion and increases life of bit. Compact bit holder keeps bits organized and secure, but is easy to carry in a pocket or pouch. Longer bit works with deep impact drivers or power drill sockets.
