Marche très bien
Utilisé pour une vis impossible à dévisser et cassée à ras => percée au centre. Après perçage, le filetage était mort. Le foret fourni (8,3 mm pour une vis M8 dans mon cas) est de très bonne qualité, perçage facile même à la main. Très satisfait également du taraud fourni dans le kit, aucun problème (n'ayant pas un tourne à gauche ou porte tarauds de la bonne dimension, j'ai utilisé une perceuse visseuse) La pose de l'helicoil et la casse de l'ergot ne posent aucun problème, même pour un débutant comme moi. Une fois posé, vissage sans souci. Seul reproche : il manque des détails sur la hauteur de l'helicoil et la profondeur de perçage et de taraudage requise. Vu qu'il s'agit souvent de réparations de dernière chance, je ne regrette pas d'avoir payé un peu plus cher pour un kit de qualité.

La qualitá si paga
Avevo necessitá di ricostruire un filetto in un carter della mia moto. Ho preferito questo prodotto per la qualitá dello stesso e perché viene fornito tutto il necessario nel kit. Scatola in alluminio con apertura a clip in plastica, all'interno qr code con le istruzioni online per l'utilizzo. Punta da trapano calibrata e soprattutto di alta qualitá, stesso dicasi per la filiera e i filetti. Strumenti per il montaggio non massicci, ma resistenti. Si consiglia comunque l'applicazione di una goccia di frena filetti durante l'inserimento per una sicurezza aggiuntiva. A lavoro ultimato ho potuto stringere la vite alla coppia di serraggio indicata dal manuale e non ho piú avuto alcun problema.
