Review on Helicoil 5546-5 M5 x 0.8 Metric Coarse Thread Repair Kit: Comprehensive Solution for Metic Coarse Threads by Alvaro Delic

I've never done a thread repair like this but when it came to potentially losing a carbon fiber bike fork to a stripped bolt hole I thought I'd give it a try. I was able to complete the repair in about 15-20 minutes and saved myself a few hundred dollars. The only complaint I have regarding this was that the plastic guide bushing around the installation tool actually made it difficult to install the coil into the new thread. I cut. I messed up a spool, pulled it out and put in a new one without the guide bushing and it stood up fine. In addition, you will need a few things that are not included in the kit. I had the drill bit, but I also had to order a T-handle wrench so I had the proper leverage for tapping.
