Review on 🔧 Alltooetools Thread Helical Coil Repair Tool Kit M10 X 1.25 SF0059E: Restoring Threading Precision Made Easy by Blake Giordano

Used to ream the spark plug hole on my son's ATV. I didn't want to spend a lot of money on a real helix coil so I decided to give this one a try. First experience for me, a few things I've learned (others may already know this): If all goes well, you can't get the spool out, and you definitely need a tool to put the spool in. I rethreaded using the included tap - the thread seemed smooth enough to turn the tap by hand - but the spool just didn't go in well, very tight and I could tell the internal threading of the spool was poor. I managed to get the spark plug out but it was very tight and if it is ever removed it will have to be tapped and screwed back in.
