Description

Version:

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.

Note:

Flute length LC = L2 + 1.5 × DC.
Form HB and HE supplied at the same price as HA.
Form HB: order with No. 122716.
Form HE: order with No. 122715 + 129100HE.
