In 1977, the KUB Trigon was the world's first indexable insert drilling tool and to this day sets new standards on the machining market. With its 84° corner angle and a variable radial installation angle, the indexable insert handles deflection forces perfectly.
Its excellent spot drilling results make the KUB Trigon particularly suitable for:
