Worked really great! I only used the smallest size, but it removed rusty screws with completely stripped heads. Using an impact driver probably helped. I actually had a hard time getting the screw detached from the bit after I removed it, which is a good sign for the function of the bits.
perfect to remove & extract damaged screw heads
Removed a 5mm stripped loctited' hex bolt brake pad pin on a motorcycle caliper with ease.
I broke a screw in the gearshift of my car trying to install an aftermarket part. I was able to get it out in a couple of minutes with this product. I went from hopeless to problem solved in a day or so. NOTE: both sides of the drill bit should be used in reverse mode.
Worked perfectly, just need to do it properly and they won't break
Extremely easy to use. I removed a broken exhaust stud on my Nissan ka24de. Happy for the price.
I am super impressed! I had four screws on my motorcycle brake fluid reservoirs that were rounded out, and this tool removed all four with no trouble. I was a little nervous to try it at first, but it worked. Just use the burnisher side to drill out the top, then flip the bit and use the removal tool. I did have to bump up one size to get the screws out, but it worked as advertised. Great tool for the price.
This is a must have; I decided to buy this due to bad experiences with breaking extractors; finally got to use it on a broken off screw in a motorcycle engine block; it was too easy and worked like a charm!
