Helicoil sticking to insertion tool.

Can anyone see what is going on? It’s only this manufacturing lot of helicoils that’s seeing this issue.

ETA: Thanks for all the replies. Will definitely double check the coil length and tap depth again, but I’m pretty sure they are to spec. Some notes.

We’ve been supplying millions of these helicoils to the customer for almost a decade.

The driver you see comes from HeliCoil direct. It’s intended for this high volume automated application.

It’s only this particular manufacturing lot that is seeing the problem.
