Review on 🔧 AB Tools-Neilsen M12 x 1.25mm Helicoil Thread/Tap Repair Cutter Kit (15pc Set) - Fixing Damaged Threads by Scott Rodriguez

used it to install an M12x1.25mm bolt in the spool, drilled a hole with a slightly larger drill bit, cut new threads with plenty of WD40 and a 10mm open ended wrench (used with an open end) and finally the installation of the coil. There was difficulty installing inserts, but I put that down to being a beginner. The last spool has done its job by using up all the spools, oh what a stroke of luck. Put the subframe on the car and successfully inserted the screw. Now the machine is functional. Thank you to the suppliers and Revain for making this possible.
