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.
