      Description

      Version:

      Cutting chisel edge with high centring accuracy due to strong core and special point geometry. High roundness and alignment accuracy of the deep hole, thanks to 4 guide chamfers. Outstanding chip evacuation due to 4 internal cooling channels from ⌀ 3.8 mm. Up to 3.7 mm ⌀ with 2 internal cooling channels. Straight major cutting edges with honed edges and special flute profile for short chips, even on long chipping materials.

      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. 123214.
      Order form HE: with No. 123212 + 129100HE.
