Abstract
A tool for metal-cutting machining of a surface of an opening particularly of a valve seat in a cylinder head of an internal combustion engines. The tool has a cutter tip with at least one geometrically defined cutting edge. The cutter tip rests on two supporting regions in the tool which are arranged at an angle α, and an angle-bisecting line runs essentially perpendicularly with respect to the active cutting edge which then is removing chips from the valve seat. A claw holds the cutting tip to the tool end. Coolant and lubricant are supplied through an outlet from the claw.
