Very comprehensive piece of kit, nice to use and you do not have to buy in bulk.

Well made and easy to use
Review by Pete Soanes
I was a bit nervous about using a helicoil kit to repair the thread in my cast iron engine block. When the kit arrived, the tools looked and felt good quality. I watched the online demo and was a bit sceptical as it looked too easy. Because the thread in the block had stripped, I didn’t drill out the old thread, but just used the tap to cut a new thread. It cut easily through the cast iron. The dual use handle did a good job of holding the tap and also inserting the wire replacement thread. The end result was a secure replacement thread in a short time and I will be confident using for future repairs. Thank you (Posted on 05/05/2018)
