KUB Trigon
The highly accurate flexible drilling tool
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.
Characteristics
- Tight drilling tolerances – Up to IT 8 are possible
- Excellent surface quality is achievable
- Machining to finished size, no separate fine machining necessary
- Flexibility during use, due to a variety of geometries and coatings
- Low machining forces, make it ideal for unstable machining conditions on less powerful machines
- Low adhesion of chips to the tool holder, thanks to a special coating
- Good centring as a result of cutting edge geometry
- Combi shank facilitates clamping in Weldon and Whistle Notch adapters
Applications
Its excellent spot drilling results make the KUB Trigon particularly suitable for:
- Machining on less powerful machines
- Machining under unstable conditions
- Creating dimensionally accurate holes
The benefit for you
- Excellent surface quality is achievable
- Machining to finished size, no separate fine machining
- For rotating and stationary usage
- Cost reduced stock requirements and easy handling as the internal and
- external indexable inserts are identical
- Outstanding price/performance ratio
