    摘要： A tool body and a turning tool for grooving operations having the tool body include a fitting member extending along a longitudinal first axis for fixing the tool body to a machine. The tool body's upper and lower clamping members each having respective inner seating surfaces facing one another and separated by an intermediate gap in which a cutting insert is insertable. A major part of the lower inner seating surface extends along a second axis perpendicular to the first axis. The clamping members are movable toward one another by a tightening device in order to secure the cutting insert in the intermediate gap. The tool body is integrally formed in a unitary piece. A hinge joint is formed between the clamping members, such that they are movable with respect to one another by turning around an axis of rotation of the hinge joint, extending perpendicularly to the second axis.

    摘要： A cutting insert has parallel first upper and lower faces, parallel second upper and lower faces, first and second side faces, first and second cutting portions, and first and second mounting grooves. The second upper and lower faces are perpendicular to the first upper and lower faces, respectively. The first and second side faces are located at respective ends of the cutting insert. The first cutting portion has a major cutting edge at an edge between the first upper face and the first side face, while the second cutting portion has a major cutting edge at an edge between the second upper face and the second side face. The first mounting groove curvedly or linearly extends from the first cutting portion oppositely to the second cutting portion, while the second mounting groove curvedly or linearly extends from the second cutting portion oppositely to the first cutting portion.

    摘要： A cutting tool has a holder and an indexable cutting insert secured therein. The holder has a head and a shank extending therefrom along a holder axis, the head having spaced apart lower and upper clamping portions located on opposite sides of a first plane containing the holder axis. The lower clamping portion has spaced apart first and second lower clamping surfaces located on opposite sides of a second plane perpendicular to the first plane, and the upper clamping portion has an upper clamping surface intersected by the second plane. The cutting insert has a peripheral surface with a plurality of circumferentially spaced cutting portions, and the second plane intersects the plurality of cutting portions. The upper clamping surface makes contact with a first abutment portion of the peripheral surface, and a second abutment portion of the peripheral surface makes contact with the first and second lower clamping surfaces.
