How to Make a Driver for Your Allen Wrench Set

Every pro has a few loose allen wrenches lying around in the bottom of their tool bags, separated from their full sets and looking for a new purpose. Turn those lonely allen wrenches into an entirely new tool by cutting off the branch of the “L” shape and creating a straight hex driver that can fit into the chuck of any power drill, just like a normal drill bit.

This process could even be done with an entire set of allen wrenches to create a collection of drivers of various sizes.
