10-Piece High-Speed Steel Screw Extractor & Drill Bit Set - Spiral Flute Broken Bolt Remover, Easily Remove Stripped or Damaged Screws, Left-Hand Drill-Bit - Complete Set with Metal Index Case

if you work on cars these are a must . extracts stripped and broken bolts easily .

worked really well

I got these to extract a screw from my cars aluminum head. The drill bit broke right away. I used a drill bit I had to drill the hole. The extractor worker perfectly.

With a lot of difficulty I managed to remove the screw that was rustedThe drill bits included did not work and refused to create a hole I had to use the ones I already hadBeware, when you create a hole to accommodate the bit it weakens the neck of the screw and the screw may break

I was having an extremely hard time removing these stripped torx screws from my car door. They were inside a hole about 1.5” deep which made way more difficult. I was able to easily remove all 4 of them with these bits which are very affordable. The quality is great. Highly recommend it.

These bits are dull from the start. They burn out quickly and are a waste of money and time. I sent them back but the seller along with amazon would not refund the money. Lied and stated what they got back was not what was sent. I got conformation emails that they received the item back. 6 months later they debited me again..Keeping amazon honest is becoming a full time job.

Was able to extract a frozen 6/32 set screw in 80yr old Hallicrafters S38 radio knob without damaging it using smallest bit and extractor. A replacement knob, if I was luck enough to find one would have easily cost twice as much as this set.

These drill bits are made of such cheap material is actually surprising. They broke within 2 seconds of drilling. Even the larger sizes. The extension bits are good enough I guess. Overall I would not recommend this but set. Only for SUPER light drilling.
