      Description

      Version:

      Very sturdy. Tight concentricity tolerances between drill ⌀ and counterbore ⌀ guarantee exact alignment.
      Special surface treatment, resulting in reduced tendency to edge build-up and improved chip evacuation.

      Application:

      Particularly suitable for NC machines due to high positional accuracy, excellent centring properties and great sturdiness. The preceding centring operation can thus often be omitted.
      For through holes for screws to DIN-ISO 273 and countersinks to DIN 74, sheet 1 form A, fine version.
      For screws to ISO 2009, 2010, 7046, 7047 (DIN 963, 964, 965 and 966).
