      Solid carbide drill plain shank DIN 6535 HA 180° TiAlN

      In stock

      Description

      Version:

      Special point geometry for generating 180° flat-bottomed holes. Low radial forces even when spot drilling on faces with up to 15° slope. Flute geometry for optimum chip evacuation. With 4 guide chamfers to stabilise the drill in the hole.

      Advantage:

      The 180° point angle permits drilling and counterboring in a single operation.

      Recommendation:

      Maximum drilling depth:
      flute length (see table) less 1.5×nominal ⌀.
      When using the solid carbide 180° drill it is absolutely essential for process reliability:
      • when spot drilling on flat surfaces to drill a pilot hole 1×D using pilot drill No. 122736.
      • when spot drilling on sloping surfaces up to max. 15° : reduce the feed rate f to 25% of the stated value. After spot drilling, the normal feed rate value can be used.

      Note:

      Form HB and HE supplied at the same price as HA.
      Form HB: order with No. 122793 + 129100HB .
      Form HE: order with No. 122793 + 129100HE.
