Review on 🔧 Inches High Carbon Pieces Extension Drill by Jerry Estrada

These extensions, like many other extensions, use a hex head screw to tighten the drill. However, the threads for the set screws seem to have been made with a hammer and chisel. The screw will barely turn in once you've pushed it all the way in and screwed it all the way in. It's just as difficult to open. I flipped it over and ended up drilling and tapping as I couldn't wait for another set. Now it works fine
