      Description

      Version:

      Spiral fluted, with 4 guide chamfers and internal cooling channels. New generation of high performance deep hole drills in the HPC range. With 135° point angle and special fg6 cutting edge tolerance for optimum generation of deep holes. High roundness and alignment accuracy of the deep hole.

      Recommendation:

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

      Note:

      To achieve good process reliability with 40×D and 50×D deep-hole drills it is absolutely essential to drill 6×D pilot hole with a No. 122736 and a 20×D co-pilot hole with a No. 123691 co-pilot drill.
      The generation of a pilot hole improves the process reliability. See also pages 116/117.
