Review on High-Quality Heli-Coil 554412 M12 X 1.5 Metric Kit: Quick & Easy Thread Repair Solution by Rob Madden

Must know how to properly thread and remove chips as with any threading and stamping project. Fits perfectly on my dirt bike's drain plug (15 KTM 250 XCW with aluminum body stainless steel drain plug). Comes with a few extra inserts so I hooked up a few buddies with the same faucet and inserts. Worth every penny!
