Humm Ball ball end mill.
It has an optimized “S”-shaped cutting edge, which allows for very gentle and smooth operation. Sintered carbide and a polished cutting edge improve machining properties and directly extend its durability. The Humm Ball line cutters are perfect for profile machining and for materials with a hardness of up to 68 HRC.
