Klein Tools 32794 Pro Impact Power Bit Set is a versatile and durable set of 26 impact power bits designed for professional electricians. Made from high-impact rated S2 steel and color-coded for easy identification, these bits are built to withstand the demands of heavy-duty use. The 1-1/4" long driver bits provide a more secure grip compared to standard 1" bits, while the bit holder and nut drivers feature strong magnets for secure bit retention. The nut drivers' minimal chamfering on the hex pockets ensures maximum surface contact for improved performance.
