Ideal to top up my existing set

Made a mistake of trying to use two short helicoils to form long thread for soft alloy, but second coil rode up and you cannot unwind. bought this set and used double length for the rest

I was in doubt..., however, it seems to work fine... easy to use and easy to setup.
