      Description

      Version:

      Straight major cutting edges and a special flute profile ensure good chip evacuation. The robust cutter geometry ensures high-performance drilling with good process reliability.
      A wide range of applications in steel materials thanks to a combination of tough ultra-fine grain carbide and extremely wear-resistant coating.

      Recommendation:

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