      Description

      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.

      Recommendation:

      Maximum drilling depth:
      flute length (see table) less 1.5×nominal ⌀.

      Note:

      For process reliability when using the 12×D drill, an initial centre drilling with NC spotting drills No. 121068 – 121130 is necessary.
      Form HB and HE are supplied at the same price as HA.
      Order form HB: with No. 123226.
      Order form HE: with No. 123225 + 129100HE.
