Version:
3-flute drill, specially developed for
use at very high feed rates. Extremely suitable for
machines with high power output and stable machining conditions.
- Special point geometry with stable cutting edges and large clearance at the centre permits very high feed rates.
- The patented point geometry is optimised for chip flow and generates low cutting forces with good chip breakage.
- With 145° point angle for low burr formation when drilling through holes.
The
sector-leading technology of the chisel point guarantees
optimum self-centring behaviour and permits
spot drilling on irregular surfaces. 3 guide chamfers guarantee a stable exit from the hole and an exact roundness of the hole.
