A double-tooth cutter with flat face grinding and a cutting-edge diameter of 1.2 mm. It is used when 90° angles have to be milled, e.g. in drillings and abutments.

For machining non-precious alloys on a cobalt-chrome basis and titanium, this tool is available as a torus cutter with a small edge radius which protects the cutting edges (only 1.2 mm diameter) – so a higher endurance is guaranteed.
