Ceramic milling cutter
The invention relates to a milling device (1), rotatable in one direction around a longitudinal center axis (A) defining a forward direction and an opposite rearward direction, comprising a front part (3) and a rear part (2). The front part (3) comprising cutting edges (4, 4') each having a longitudinal extension, the front part (3) comprising chip flutes (5, 5') each having a longitudinal extension, the front part (3) is made of a monolithic piece of ceramic. The rear part (2) is configured to be fixed in a rotatable tool body or a rotatable chuck. The rear part (2) is made of a monolithic piece of cemented carbide. A front end surface of the rear part (2) having a smaller area than a rear end surface of the front part (3), the front end surface of the rear part (2) and a rear end surface of the front part (3) being permanently bonded or brazed to each other by a joint.
