Two in one design works with 1/4 inch hex bits and 1/4 inch drive sockets. Work smarter and faster by reducing time changing between a bit holder and socket holder. Convert from one to the other with a simple push-pull mechanism. Pull the sleeve down to expose the 1/4 inch drive socket holder, and pull the sleeve up to retain your 1/4 inch hex driver bits. Drop forged chrome vanadium steel for strength and durability.
