🔧 WIN.MAX M10X 1.25 X 13.5MM Thread Tool Kit Auto Car Pro Repair Helical Coil Set: Premium Quality Automotive Repair Equipment Review

Excellent Yamaha suspension thread repair kit. This was my first experience with Helicoil. Super easy to do. This kit contains everything you need to install new threads.

The only problem I had was the drill that came with the kit, you need a drill with a half inch chuck, your normal household drill only has a 3/8 chuck so I had to either buy a drill bit with a half inch chuck or buy a proper reduced shank drill bit that fits a 3/8 chuck.

First, the drill bit must be solid sheet metal, as it will round off immediately when attempting to clear a damaged hole. The supplied tap then didn't seem to match the external threads of the supplied coil because after drilling a hole with another drill bit I had on hand and then tapping with the supplied tap, the supplied coils would not screw at all. I tried 4 of the coiled coils that came with it and…

The kit helped restore two beveled bolt holes but not as smooth as I had hoped. like a hot knife through butter. There are no complaints. The faucet works well, there were no particular problems with it, but the second hole required more force than the first. The tap showed no signs of dulling, so I have to assume I cut into material, or maybe I didn't drill quite straight. I did, the coils leaked current and were tolerable to even start. I ended up buying another set of coils (I wanted longer…
