      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. With 140° point angle and special j6 cutting edge tolerance for optimum generation of a pilot hole.

      Recommendation:

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

      Note:

      For deep-hole drilling deeper than 12×D a pilot hole is recommended, and for deep-hole drilling from 20×D to 30×D it is essential.
      The generation of a pilot hole always improves process reliability.
      Form HB and HE supplied at the same price as HA.
      Form HB: order with No. 122738.
