The Irwin Tools 1840391 34-Piece Impact Series Automotive Fastener Drive Set is part of the new line of Fastener Drive bits designed for use in impact drivers. While most screw driving bits are simply compatible with impact drills and drivers, Irwin'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. Irwin's Impact Series bits have three times 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. The 34-Piece set comes in an Impact Series Drawer Set Case for organization and protection. This set contains 9 2-Inch Power bits that include #1, #2, and #3 Phillips bits, T10, T15, T20, T27, T30 and T40 Torn. There are 3 3-Inch Power Bits that include #1, #2 and #3 Phillips. There are 5 3-1/2-Inch Power bits that include T15, T20, T25, T27 and T30 Torn. This set also has 3 Socket adapter (1/4-Inch, 3/8-Inch, and 1/2-Inch) and 3 Nutsetters (1/4-Inch, 5/16-Inch and 3/8-Inch). To round out the set, there are two extensions with a 1/4-Inch Hex Shank, one is 2.5-Inch long and the other is 6-Inch long. This set will provide the professional automotive technician with a wide variety of lengths and bit configurations to get their jobs done.
