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 Craig Sexton

The taps look good and cut aluminum threads with ease. Each tap, punch, drill and wire inserter is clearly marked with its size. There are 25 spools in each size except 1/2 and M12, both containing 10. I noticed that some boxes actually had more than 25. I was able to fix the threads holding my car's thermostat housing. This kit paid for itself in one repair. It really gives me the confidence to be prepared for any broken threads when working on my car. The only issue I had was that some of the slots in the case were keeping the faucets loose. This caused some of them to fall out and rumble in the hull. I was able to fix this by dropping hot glue into the grooves. Also, this kit does not include a crank, so you need to bring one. I'm sure it could be improvised, but I didn't want to risk making bad subjects. Overall I highly recommend this set, its value compared to more expensive sets is amazing.
