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

Okay, I know how to install a spiral coil, but this kit was, frankly, complete junk. 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 decided on none. Just recycle the kit, save money and buy a different brand kit or just buy the right stuff from McMaster.
