1 . CBN ground flute
CBN ground spiral flutes enable very sharp and burr-free cutting edges compared to the ordinary milled flutes. Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily. The optimized chip flow protects the cutting edges and reduces built-up edges and cold weld marks. due to these special features, cutting performance and tool life are extended significantly.
2 . Radially adjusted relief produced by CBN grinding
Each step has a radially adjusted relief produced by CBN grinding that relates directly to the diameter of the step.This means the cutting edge is always the highest point of the diameter.
3 . Flute
Each step is axially CBN relief ground. This means the cutting edge is always the highest point of the axial cutting axis.
4 . CBN ground relief angle
The cutting edge of each step has relief angle. This means the cutting edge is also the highest point in advance direction.
5 . CBN ground bit with split point DIN 1412 C
The CBN ground bit ensures centering and spot-drilling even in thin-walled material
