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.
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.
- 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.
- With 145° tip 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.
Note:
Flute length LC = L2 + 1.5 × DC.
