Très belle qualité

Trae instrucciones detalladas de uso, viene en una caja de buena calidad, y las herramientas también se sienten muy bien hechas, ya pude reparar un orificio de bujia, y el scooter está funcionando sin problemas

Worked like a charm, and hasn't lost compression. When using on a ttr125 head, I had to cut a couple threads off as it was a little bit too long. But it's not marketed for a ttr125, and its working fine so A+.

To be honest, I did not expect much from a set this cheap but was pleasantly surprised. A set like this would usually set me back AUD $100+ and since it was a metric fine thread, would have been a special order and taken weeks to receive.For half the price of the name brand, I had these express delivered in a week.They worked just as well as the name brand helicoils.At first I expected the drill to be blunt after first hole or the cutting rake angles to be off, its still as sharp after drilling 10 holes and the holes drilled to the correct size.Then I anticipated the tap would struggle and break. It didn't. Tap cut threads perfectly, tap is still sharp. I recommend an appropriate cutting compound is used for tapping. I used Trefolex.Product was used on 12mm hot rolled mild steel plate.

Le foret, le taraud et l'outil de pose ne sont pas de trop mauvaise qualité, attention cependant à ne pas tarauder dans du métal trop dur. Cependant les inserts sont de trop mauvaise qualité. L'idéal serait d'acheter ce kit pour avoir les outils mais aussi d'acheter des inserts de meilleurs qualité à part.

Impossible de s'en servir, les douilles ne sont pas de la taille du forêt !
