Review on 🔧 HeliCoil Helicoil 5546-6: High-Quality Metric Coarse Thread Repair System by Jerry Mangum

I thought this thing would save me and it seems so, but it really didn't. The product is really good and only worked on 2 of the 3 holes I had to fix. My black lead screw is broken. There is a small piece of metal at the tip of the guide tool that I broke off while repairing the 2nd hole. I was lucky enough to finish the 2nd hole. Everything works fine, but the fact that it broke so easily honestly pissed me off. I have reworked the valve cover holes on a honda d16z6 engine and repaired the aluminum hole and also did not use power tools. It just sucks, I have to buy a second set to complete the renovation.
