Klein Tools ProFlex 33801 Impact Driver Bit Set, 40-Piece, Tool Reinforced

Klein Tools ProFlex Impact Driver Bit Set, 40-Piece, Tool Steel ✓ Prevents drill bit wandering ✓ Works on dull and damaged bits ► Extend Your Tool Accessories Life

Klein Tools designed a set of ProFlex torsion zone impact driver bits for the expert tradesman and do-it-yourself enthusiasts. All of the bits are made of high-impact-rated S2 steel and feature an optimized torsion zone that absorbs impact forces to increase the lifetime of the bit. The 3 in bit holder and 1/4 in and 5/16 in nut drivers have tough magnets to easily hold bits and fasteners in place. Minimal chamfering on the nut drivers hex pockets increases surface contact between the nut and driver for better performance. All 40 pieces fit in a durable, impact-resistant case featuring alloy hinges, a stay-shut latch and modular stackability with other cases of similar design.
