KUB Trigon® indexable insert solid drill combination shank 3×D

Execution: Offset drilling: diameter-dependent up to 1.5 mm. Special manufacturing process for extremely large chip spaces with maximum rigidity. Specific positioning of the indexable inserts for chip-free drilling and precise dimensional accuracy (±0.1 mm in most cases). Internal cooling directly at the cutting edges (sophisticated geometry ideal for minimum quantity lubrication). A coolant pressure of 3 − 10 bar is sufficient. Suitable for both stationary and rotating applications. Note: Caution! A disc falls off upon drill exit. Risk of injury with rotating workpieces! Please take safety precautions. Available upon request - left-hand cutting; - 2×D, - other diameters; - special designs - torsional vibration dampers for ABS for low-vibration machining, with maximum tool life and minimal noise level. Delivery includes: Clamping screws (without indexable inserts). Usage: With indexable inserts No. 236740 − 237080.
