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.
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.
