A cutting tool for grooving and turning operations has a removably securable cutting insert. The cutting insert is clamped in an insert holder with a longitudinally extending insert receiving slot lower surface. The insert receiving slot lower surface has two spaced apart contact sections, including a first contact section at a rear end having a V-shaped slot clamping surface with a wedge angle α1 in clamping contact with a first V-shaped insert clamping surface of the cutting insert lower surface also with a wedge angle α1, and a second contact section at a front end having a V-shaped slot clamping surface with a wedge angle α2 making clamping contact with a second V-shaped insert clamping surface of the cutting insert lower surface also with a wedge angle α2, where α1 and α2 are different. |
