  • Patent number: 9737938
    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 ? smaller than 80° and such that the upper extension plane is at a radial tipping-in angle ?60°??f??25° and at an axial tipping-in angle ?20°??m?0°, such that an angle of inclination ? of the main cutting edge portion is within the range 15°???50°.

  • Patent number: 8684640
    Abstract: Reaming tool includes a head and a detachable cutting insert fixed in a seat. The seat includes radial, tangential, and axial support surfaces, while the cutting insert has a mirror-symmetrical polyhedron shape comprising six limiting surfaces, viz. two chip surfaces and at least two clearance surfaces, a number of alternately usable, identical cutting edges formed in transitions between the chip and clearance surfaces. A female- or male-like securing means co-operates with a complementary, male- or female-like securing means in the seat, more precisely in an inactive, contactless state as long as the cutting insert is held pressed by the cutting forces against the axial support surface. The securing means is activatable when the cutting insert is unintentionally distanced from the axial support surface against the action of a clamping member. Tool head and reaming insert for the tool are disclosed.
