Abstract
A turning tool includes a coupling portion, which extends along a coupling axis, the coupling axis defining a longitudinal axis of the turning tool. The turning tool includes a first cutting element and a second cutting element, wherein the first cutting element has a first cutting edge. The second cutting element has a second nose cutting edge separating and connecting a second forward cutting edge and a second rearward cutting edge. The first cutting element includes a first top surface, and the second cutting element includes a second top surface. A first top surface and the second top surface face in the same or substantially the same direction.
Claims15
A turning tool comprising:
- a coupling portion, wherein the coupling portion extends along a coupling axis, the coupling axis defining a longitudinal axis of the turning tool;
- and
- a first cutting element and a second cutting element, wherein the first cutting element includes a first cutting edge, wherein the second cutting element includes a second nose cutting edge separating and connecting a second forward cutting edge and a second rearward cutting edge, wherein the first cutting element includes a first top surface, wherein the second cutting element includes a second top surface, and wherein the first top surface and the second top surface are facing in a same or substantially the same direction, wherein the first cutting element includes a first forward cutting edge and a first rearward cutting edge, wherein the first cutting edge is in the form of a first nose cutting edge, and wherein the first nose cutting edge separates and connects the first forward cutting edge and the first rearward cutting edge, wherein in a top view, a first bisector between the first forward cutting edge and the first rearward cutting edge forms an angle of 45-90° in relation to a second bisector between the second forward cutting edge and the second rearward cutting edge, wherein the first cutting element is arranged such that when turning in a first direction perpendicular to the coupling axis, the first forward cutting edge forms a first entering angle of 3-45°, and wherein the second cutting element is arranged such that when turning in a second direction, opposite to the first direction and perpendicular to the coupling axis, the second forward cutting edge forms a second entering angle of 3-45°.
