wesleydrill 13PCS Left Hand Drill Bit Set 1/16"-1/4" Titanium Twist Reverse Drill Bits Fit for Cutting Metal, Cast Iron, Hard Plastics and Wood, and Softer Materials

I've only had to use them once on a broken bolt so far. But it drilled half way down until it but and spun the broken piece out. So worth the $ I spent already, too me anyways lol

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.

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!

I needed to remover a broken bolt from my car and broke three bits befor the bolt came out. The bits arejust 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.
