Speed Out Titanium Damaged Screw Extractor Kit, 4 Piece Set

I've had very good results with these extraction tools. I've had some fasteners that were installed with locktite red compound and were in places that you could not apply heat to break that bond because of the painted surface. I drilled the fastener head and then used the opposite end to extract the messed up bolt. Word of caution, never use these with an impact drill, the extractor is hardened so it can bite into the fastener and using an impact tool with snap it.

It did not extract a screw. Tried with two different drills. Side "B" just spun in the hole Side "A" made. This product did not work at all for me.

This is by far one of the best tools in my tool box ever made. These make stripped nuts & bolts as easy to get out as if they weren’t stripped at all, and definitely reasonably priced and arrived quickly. Has definitely bailed me outa problems many times, another great Amazon buy

This thing looks so easy to use in the videos, but in real life it is nearly impossible to get the screw out.

This extractor set seems to be of good quality and should last a long time. Shipped quickly with no difficulties.

This may sound obvious, but you have to read and follow the instructions. The grippy ends don't grip well if the head isn't properly prepared with the burr ends, and the bits in general don't extract well unless you use a drill at slow speed while applying consistent pressure. Using an impact driver just doesn't work well.

And the hotel we have a lot of strips screws so this comes in very handy. Definitely will buy it again.

Drill bit skidded around screw shaft. After drilling a hole with another bit, found the extraction end head angle was too great to get a grip on the screw shaft. Then when trying to return it was notified that there is up to a 80% restocking fee and I would be liable for return postage. All around bad deal.
