Irwin 1840315 Fastener Drive Set, 33-Piece, Steel, Black Oxide

While most screwdriving 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 3X longer life than traditional bits. Manufactured with heavy-duty, cold forged, high-grade steel, they'll withstand extremely high-torque output. Plus, a black oxide finish resists corrosion and increases the life of the bit.

Made of steel with a black oxide finish, with includes (1) 1837398 Impact Insert Bit (1) 1837401 Impact Insert Bit (1) 1837403 Impact Insert Bit (1) 1837405 Impact Insert Bit (1) 1837409 Impact Insert Bit (1) 1837411 Impact Insert Bit (1) 1837412 Impact Insert Bit (1) 1837499 Impact Power Bit (1) 1837502 Impact Power Bit (1) 1837507 Impact Power Bit (1) 1837546 Impact Nutsetter Lobular Magnetic (1) 1837549 Impact Nutsetter Lobular Magnetic (1) 1837552 Impact Nutsetter Lobular Magnetic (1) 1837575 Impact Socket Adapter (1) 1837578 Impact Bit Holder Magnetic with C-Ring (1) 93551 Compact Magnetic Screw Guide (2) 1 Phillips Impact Insert Bits (2) 1 Square Recess Impact Insert Bits (2) 1837455 Impact Power Bits (2) 3 Phillips Impact Insert Bits (2) 3 Square Recess Impact Insert Bits (3) 2 Phillips Impact Insert Bits (3) 2 Square Recess Impact Insert Bits.
