Quality
High quality tool, HSS drill bit and a good quality HSS German made tap. Very easy to use which made for an exeptional reair. I used this to repair a aluminium kayak side loading roof rack.

Not the stated lenght
I decided to buy this product for two reasons. The brand name and very important; the lenght of v- coil that was stated as 1.5D.Quality not at fault, but v-coil rather 1D. Now I have to order new set of v-coils from elsewhere.Suggestion to whoever put these kits together - add a selection of lenghts.

A great way to repair a stripped threD
There's few things worse than having a thread strip on your motorcycle/car, I had threads fail on my classic Japanese motorcycle., not a nice feeling. I actually bought an m7 v coil repair kit for my cam cover threads a year or so before, I was very pleased with the repair back then. The m8 repair kit did a solid repair this time too. I really like the v coil kit, it's easy to use, does a great job and isn't a bad price either .
