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.
