      Description

      Version:

      Spiral fluted, with 6 guide chamfers and internal cooling channels.
      New generation of high performance pilot drills in the HPC range.
      With 140° point angle and special p6 cutting edge tolerance for optimum generation of a pilot hole. High alignment accuracy and roundness of the pilot hole.

      Recommendation:

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

      Note:

      For deep-hole drilling deeper than 16×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.
