Heli coil ket
After snapping a bolt in a alloy head I had the option to remove the head and replace it or try and drill it out and use a helli coil, so I ordered this kit and got to say it worked a dream,1- reasonble price2 - decent quality3 - cost effectiveOnly thing to say is make sure the hole your drilling out is 100% straight as there's no try agains

Thread repair kit
Just the job

Saved my bacon!
Brilliant little kit, got me out of a spot of bother when I found out that one of my engine cover bolts had stripped the thread from the main crankcase.Really easy to use, and did the job perfectly.It would be nice if there was a tool included for the thread taps, hence the 4 stars instead of 5 but then again, you imagine most people would already have a tap and die set or at the very least, you could use a cordless drill set on slow.Overall, a really great little kit to have in the garage, just in case.

I don't need to part out my Drz 400. pheeew.This is an incredible useful piece of kit, however I realised that the drilling bits are rubbish to cut into metal, as it takes a lot of effort. I realized it after I used another bit I had that cut into the steel as butter
