🔧 Precision Thread Repair: M10 x 1.25mm x 15mm Thread Kit (3221-M10F) Review

The product worked great but be aware that it comes with little to no instructions. If this is your first time using this type of tool, you will need instructions or YouTube videos to show you how to use it. I found a helpful video on YouTube that solved the problem for me.

I drilled the aluminum holes with an 11/32 drill bit, tapped them with the included M10x1.25 thread (adding cutting fluid or some sort of lube), put in a perma coil (knocked out a small pin),
