      Description

      Version:

      3-flute drill, specially developed for use at very high feed rates. Outstandingly suitable for machines with high installed power and stable machining conditions.
      • Special cutter geometry with stable cutting edges and large clearance at the centre enables very high feed rates.
      • The patented tip is optimised for chip flow and generates low cutting pressure with good chip breakage.

      The sector-leading technology of the drill point guarantees optimum self-centring behaviour. 3 guide chamfers guarantee a stable exit from the hole and an exact roundness of the hole.

      Recommendation:

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

      Note:

      For process reliability when using the 12×D deep-hole drill, an initial centre drilling with an NC spotting drill No. 121130 with 155° point angle is necessary.
