Review on Highking M14 x 1.50 mm Metric Thread Repair Kit - Compatible Hand Tool Set for Auto Repairing (M14-1.5) - Thread Repair Insert Kit & Tools by Maurice Rivera

After a clumsy technician (without telling me!) twisted the eyebolt on my wife's Audi TT, the hub either had to be replaced or tried. As reported the center drill does not fit the 1/2" drill chuck. Literally 3 minutes on a bench grinder and the shank can be reduced to 1/2". To make sure it doesn't rotate I also ground 3 planes in the shank to catch the jaws of the chuck. Worked great. The tap itself seemed good quality to me and tapped my steel hub with no problem. I had to machine about 4 turns of the insert as the sleeve is not as deep as the inserts used supplied with the kit.Generally I am very satisfied with the result and the quality of the components.
