ABSTRACT:
A tool for chip removing machining, including a basic body and a cutting insert detachably connected to the basic body via an interface. The interface includes a first connecting surface formed in the basic body in which a chute is formed that has two side-flank surfaces diverging from a bottom. The interface also includes a second connecting surface formed in the cutting insert in which there are formed a number of male members having converging side-flank surfaces that abut against the side-flank surfaces of the chute, and at least one transverse shoulder surface that abuts against a transverse stop surface in the connecting surface of the basic body. When at least one first male member in the connecting surface of the cutting insert is in engagement with the chute and has flank contact with the side-flank surfaces of the chute, a lower bearing surface of a second male member laterally spaced-apart from the first male member abuts against a support surface located in the connecting surface of the basic body and spaced-apart from the chute.
