Version:
Developed for use with
very high cutting speeds. Outstandingly suitable for machines with
low installed power and high speeds.
- Clear reduction in cutting forces due to special cutter geometry.
- Coating for best wear resistance even at high process temperatures.
- Polished flutes for good chip clearance.
A
slim chisel point and the
special arrangement of the 4 guide chamfers ensure
high positioning and alignment accuracy. Optimised micro-geometry for increased working life and performance capability.
