Review on 🧰 Pikwo 263Pc Thread Repair Kit, High-Speed Steel Helicoil Repair Kit - SAE & Metric, 1/4-inch 5/16-inch 3/8-inch 7/16-inch 1/2-inch - M5 M6 M8 M10 M12 Kit with Thread Gauge by Ethan Carpenter

This is a quality kit. The kit contains everything you need to repair a stripped thread. It comes with 10 different sizes of helicoil for thread exchange for imperial and metric threads. This kit basically contains a repair of all the standard sized screws that would have been stripped. This is a very complete kit containing a quality drill, tap, coil insertion tool and a punch to break the tab on the coil after insertion. Each size comes with approximately 25 spiral spools. I am very satisfied with this kit. I bought this as I need to fix 1 threaded hole that was cleaned on my engine block. When I finished rebuilding the engine I used 6 of them. I think I needed this kit more than I thought I would. This is a great set for the money and a great price. I definitely recommend it.
