Klein Tools has designed a set of Impact Power Bits for the professional electrician. All the bits are made of high-impact rated S2 steel and color coded for easy identification. The nut drivers have strong magnets, and are also designed longer so they reach easily into junction boxes. Minimal chamfering on the nut drivers hex pockets increases surface contact between the nut and driver for better performance. You can find these drivers along with additional size and tip bits in our Pro Impact Power Bit Set with Case (Cat. No. 32799).
