I only used one drill bit one but it worked great. A screw broke off inside a tapped manifold on a string trimmer. It was really on the small end for an extractor. I was able to use the left handed drill and it backed right out.

I have used these to remove broken bolts. Just reverse drill the broken bolt and when the drill catches it winds the bolt out without even using an easy out tool. And if the bolt is still stuck, then you can still knock in an easy out in the hole to remove it.

I needed to remover a broken bolt from my car and broke three bits befor the bolt came out. The bits are just sharp enough to cut into the bolt and work but be careful of placing pressure on them. I kept breaking bits until one worked. They were worth the money. I woiuld buy it again because it is a good solution to a broken bolt issue.

I had a few guns laying around with stripped hex screws for their accessories (Don't buy cheap crap, kids) and I used these to prep the holes for the actual extractors. Turns out, the actual extractors kept needing bigger holes since they wouldn't bite properly, and by the time I drilled for the 3rd time or so, this alone removed the screws. Soooo yeah! Great stuff!

Why did you pick this product vs others?: Worked as expected and was a great value for the money!

Have been tearing my hair out trying to remove a rounded off and recessed 3 mm stainless steel screw. Tried just about everything: rubber band, torx bits, super glue and JB WELD, screw extraction kit, I even tried soldering an old bit to the screw and nothing worked. This thing finally, finally bit into the screw and extracted that screw! I started with what I thought would have worked, the smallest 1.5 mm bit. It cut into screw and bored down til it hit the shaft of the screw but refused to go any further, I was about to throw in the towel when I decided to try the next bit up and that was the ticket! Very happy with result and the bits didn’t look very worn after. These are staying in my collection just in case!

Should have been 13 drill bits, but only came with 12.

good quality

The box appears cheap & nasty. Difficult to open & close. I hope the drill bits will be better. Not sure I have much confidence.
