Version:
3-flute drill, specially developed for
use at very high feed rates. Outstandingly suitable for
machines with high installed power and stable operating conditions.
- Special cutter geometry with stable cutting edges and large clearance at the centre enables very high feed rates.
- The patented tip is optimised for chip flow and generates low cutting pressure with good chip breakage.
The
sector-leading technology of the drill point guarantees
optimum self-centring behaviour. 3 guide chamfers guarantee a stable exit from the hole and an exact roundness of the hole.
