Hard-wearing RUnaTEC coating
The RUnaTEC coating combined with HSSE-Co5 material delivers up to three times longer tool life compared to standard countersinks.
Shank design for high compatibility
The three-flat shank prevents slipping in the drill chuck and is suitable for hand drills, pillar drills, and CNC machining centres.
Four cutting edges for precision
Distributing the forces across four cutting edges saves up to 50% in time while producing chatter-free countersunk holes.
