Procat Screwdriver Set 4 pieces

This set helps you get rid of stripped and stuck screws. Drill a hole in the head of the stripped/broken screw with the drill tip on the bit, then turn the bit around. The reverse thread tip on the other end fits perfectly into the new socket you've made, so you can now screw out the stripped screw! Removing a broken screw couldn't be easier. The set has four different sized tips for different screws.

For removing broken screws
