Universal cutter from the Humm Uni line.
It has been adapted to work with many materials. Thanks to the increased core thickness, Humm Uni cutters are characterized by high stiffness and the possibility of bending during heavy machining is eliminated. The chip groove of the tool has been optimized to improve chip evacuation during operation.
