Description
Version:
Multi-edged, spiral fluted counterbore with recess in face for fitting various pilots. Pilot is clamped with a screw in the counterbore.
Application:
One counterbore can be used for several pilot holes of different diameters due to the interchangeable pilots.

For suitable reducing adapters for tools with MT shanks see No. 343000-343530.
The dimensions relate to screws DIN 912, 6912, 7984 and ISO 1207. However, with an appropriate pilot, a counterbore can be used for other screw sizes or counterbore / pilot diameter combinations.
