A method for cutting a groove of a predetermined groove width in a work piece, comprising the steps of: - providing a metallic work piece having a peripheral surface; - providing a grooving tool comprising 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; - 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, the method including the further steps of selecting the grooving tool such that the blade portion comprises: - opposite first and second surfaces (4, 5), wherein the blade width is defined as a shortest distance between the first and second surfaces (4, 5); - opposite third and fourth surfaces (8, 9); - a fifth surface and an opposite blade portion end, wherein 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; - selecting the grooving tool such that the insert comprises a rake face, and a main clearance surface; - positioning the insert in the insert seat such that the main clearance surface and the third surface are facing the same direction characterized in that the method comprises the further step of arranging the blade portion such that 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. - providing a metallic work piece having a peripheral surface; - providing a grooving tool comprising 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; - 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, - opposite first and second surfaces (4, 5), wherein the blade width is defined as a shortest distance between the first and second surfaces (4, 5); - opposite third and fourth surfaces (8, 9); - a fifth surface and an opposite blade portion end, wherein 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; - selecting the grooving tool such that the insert comprises a rake face, and a main clearance surface; - positioning the insert in the insert seat such that the main clearance surface and the third surface are facing the same direction
