Abstract: A method for cutting a groove of a predetermined groove width in a work piece, including the steps of providing a metallic work piece having a peripheral surface; providing a grooving tool including a blade portion having a constant or substantially constant blade width, and an insert having a maximum insert width defined by a main cutting edge; selecting the insert width to be greater than the blade width; connecting the grooving tool to a machine interface of a machine tool; rotating the work piece about a rotational axis thereof in a rotational direction; and cutting a groove in the work piece by moving the tool in a feed direction towards the rotational axis of the work piece, such that the groove width is equal to or substantially equal to the insert width and such that a tangential cutting force is directed towards or substantially towards the machine interface.

Abstract: A blade portion for a grooving tool includes opposite first and second surfaces, a blade width thereof being defined as a shortest distance between the first and second surfaces, opposite third and fourth surfaces, and a fifth surface and an opposite blade portion end. The blade width is constant or substantially constant from the fifth surface up to the blade portion end. An insert seat separating the third surface and the fifth surface is arranged to receive an insert having a main cutting edge, an associated rake face, and an associated main clearance surface. The main cutting edge defines an insert width being greater than the blade width. A shortest distance from the fifth surface to the opposite blade portion end is greater than a shortest distance from the third surface to the fourth surface.

Abstract: 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.
