## Description

Klein Tools designed a set of ProFlex Torsion Zone Impact Driver Bits for the professional 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-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 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 steel hinges, a stay-shut latch and modular stackability with other cases of similar design.

### ⭐⭐⭐⭐⭐ Review
*by M***A on 4 February 2026*

Klein bits are phenomenal. Very well made, last forever, and this coming from a guy who uses nothing but Milwaukee and HILTI for my power tools. They are superior to Milwaukee's bits by miles, and I usually will only buy Klein or DeWalt when it comes to bits for my impact driver and or drill bits for my M18 fuel hammer drill. They hold up very nicely, are easy to take out of the pack it comes in, which is also built very well, and can "mate" to other Klein boxes as part of their "packout" system. I Particularly like their nut drivers as the magnet and tool itself is simply superior to other brands.
