Review on 💎 Uxcell Diamond Coated Drill Bit: Ideal for Marble Drilling Efficiency by Dusty Tofte

This product is not intended but works perfectly. With a little guide I was able to drill the broken screw extractor out of the broken bolt I was dealing with. I couldn't be happier. It took about 17 of them to get through a bolt puller and it took a lot of fighting to make it. If you're on a roll, they can certainly get the job done. The build quality is pretty poor and I crushed a few of them by tightening the drill bit.
