      Description

      Version:

      Strong core and special point geometry ensure the cutting chisel edges maintain high self-centring accuracy.
      Straight cutting edges
      with slight edge hone and a special flute profile produce short chips.

      Recommendation:

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

      Note:

      For process reliability when using the 12×D deep-hole drill, an initial centre drilling with No. 121068– 121130 or 3×D pilot drilling operation with No.122736 is necessary.
