Csavaros fúró GISS Cutline 892912

Solid carbide drill 3xD with internal coolant - SCD range.
Tip angle: 140 ° - 30° helix angle – Split point
Cylindrical shank DIN 6535 HA with h6 tolerance
Internal coolant to ease chips evacuation, reduce heat, increase lifetime & performance of the drill.
CUPMM coating for universal & multi-material application. Extra fine AlCr based multilayer coating for high thermal resistance, stability at high cutting speed & increased lifetime.

Drill conception studied for high stability during the drilling operations: guiding chamfers, sicle cut technology, self-stabilisation & special geometry reducing friction.

- m7 drilling tolerance.
- Quality of holes: H8-H9
