If you have a bolt that you need to tighten-up, screw-in, or work on, but it's old, nasty, rusty, and won't allow you to screw a nut onto it, chances are you'll have to go find a new bolt with the exact same size and length. Though, you wouldn't have to if you had the Uniburr! It's a unique drill attachment that lets you easily fix the ends of broken or rusted bolts to easily reattach a nut.

The Uniburr bolt repairing tool works by shearing the metal on the end of the bolt layer by layer. It slowly removes the damaged threads on the bolts to allow for an easy nut start.
