Impact Driver Bit Set, 35-Piece

All of the bits are made of high-impact rated S2 steel. The 3-Inch bit holder and 1/4-Inch and 5/16-Inch nut drivers have strong magnets to easily hold bits and fasteners in place. Minimal chamfering on the nut driver hex pockets increases surface contact between the nut and driver for better performance. All 35 pieces fit in a durable, impact-resistant case featuring steel hinges, a stay-shut latch and modular stackability with other cases of similar design.
