Description
Developed for use with very high cutting speeds. Outstandingly suitable for machines with low power output 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 edge 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.
