Abstract: A round cutting insert for a milling tool having a center axis and a neutral plane extending perpendicularly thereto. The round cutting insert includes a circumferential side surface surrounding the center axis between upper and lower round main surfaces. An upper cutting edge is formed along the intersection of the upper round main surface and the side surface. A plurality of elongated support grooves are arranged in the side surface. Each elongated support groove has a bottom surface extending in a lengthwise direction with opposite flank surfaces converging toward the bottom surface and extending in parallel with the lengthwise direction of the elongated support groove. The lengthwise direction of each elongated support groove forms an acute angle with the neutral plane as seen in a side view. At least one of the opposite flank surfaces of each elongated support groove is configured as a side support surface.

Abstract: An indexable and double-sided round cutting insert includes an upper and lower side. A center axis extends between the upper and lower side and a median plane extends perpendicular to the center axis and is situated halfway between the upper and lower side. A side surface has an upper and lower positive clearance surface at an upper positive clearance angle with respect to an upper cutting edge and a lower positive clearance angle with respect to a lower cutting edge. A plurality of protrusions extends along the side surface and protrude in a radial direction perpendicular to the center axis. Each protrusion includes an outer surface, which along the center axis, extends such that a first radial distance from the center axis to the outer surface in the median plane is at least equal to or greater than a second radial distance from the center axis to the outer surface.

Abstract: A face milling tool includes a tool body having an axial front end surface with several seats. Each seat has support surfaces for rotationally locking and supporting a tangential cutting insert in the seat. One of the support surfaces is a flat axial support surface for supporting the tangential cutting insert in an axial direction defined by the central rotation axis. The flat axial support surface extends perpendicular to the central rotation axis and is situated axially foremost in the seat. A side wall of each seat is formed out of round side support surfaces. Each tangential cutting insert includes an axial back side with a flat axial contact surface abutting the flat axial support surface and a projecting member extending axially from the flat axial contact surface and having a circumferential side surface forming out of round side contact surfaces abutting the out of round side support surfaces.

Abstract: An indexable tangential cutting insert for a milling tool includes two opposing side surfaces and four identical lateral surfaces extending between the side surfaces. Each lateral surface of the insert is provided with a support surface configured to be supported by, on one hand, a corresponding support face of a pocket of a tool body providing an axial support to the insert in two of eight index positions and, on the other, a corresponding support face of the pocket providing a tangential support to the insert in two other of said eight index positions. Each lateral surface of the insert is provided with a single second support surface being concave as seen in a direction perpendicular to said side surfaces and extending diagonally across the lateral surface.

Abstract: A cutting tool has a tool body having at least one pocket, at least one cutting insert releasably fixed to the pocket and a fastening device for securing the insert in the pocket. The pocket has a raised portion) with a flat upper support face arranged to be received in a recess of the insert and support the insert by receiving a bottom surface of the recess bearing on the support face. A projecting member of the raised portion has delimiting walls designed to bear against border walls of the recess of an insert for establishing mutual contact therewith and prevent rotation of the insert in the pocket by receiving a rotational moment acting on the insert in an active chip-removing state of the tool.

Abstract: An indexable tangential cutting insert (4) for a milling tool comprises two opposing side surfaces (13) and four identical lateral surfaces (16, 17) extending between the side surfaces. Each lateral surface of the insert is provided with a support surface (32) configured to be supported by on one hand a corresponding support face of a pocket (3) of a tool body providing an axial support to the insert in two of eight index positions and on the other a corresponding support face of the pocket providing a tangential support to the insert in two other of said eight index positions. Each lateral surface (16, 17) of the insert is provided with a single said second support surface (32) being concave as seen in a direction perpendicular to said side surfaces and extending diagonally across the lateral surface.
