Description
3-cutter tool, specially developed for use at very high feed rates in aluminium.
Outstandingly suitable for machines with high power consumption and stable machining conditions.
- Specially developed cutter geometry, designed for very high feed rates, reduced cutting pressure and controlled chip breaking.
- Precision flute profile for reliable evacuation of chips.
- Achieve outstanding feed rates and tool life thanks to the third cutting edge.
The sector-leading technology of the drill 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.
