Applications
Fonctionnalités
1. Embout d’alésage de haute précision pour les applications de la gamme de tolérance de trou H7
2. Permet d’appliquer des vitesses de coupe et des avances plus élevées que les alésoirs en carbure monobloc ou brasés qui garantissent ainsi une productivité élevée
3. 2 types d’embouts d’alésage sont disponibles en fonction des types de trous
