Abstract

A face milling tool includes a tool body having a central rotation axis around which the tool is rotatable, and at least one insert seat formed in a transition between a front end and an envelope surface of the tool. The tool further includes at least one cutting insert mounted in the insert seat, the cutting insert having an upper side defining an upper extension plane, a cutting edge extending around the circumference of the upper side, and a lower side defining a lower extension plane directed towards the bottom support surface of the insert seat. A center axis extends perpendicularly through the upper and the lower extension planes. The tool is configured such that a main cutting edge portion is at an entering angle κ smaller than 80° and such that the upper extension plane is at a radial tipping-in angle −60°≦γf≦−25° and at an axial tipping-in angle −20°≦γm≦0°, such that an angle of inclination λ of the main cutting edge portion is within the range 15°≦λ≦50°.
