Abstract
A tool for chip removing machining, including a basic body and a replaceable cutting insert that has a center axis and is detachably mounted in an insert seat formed in the basic body. The seat is delimited by a bottom surface and at least one side support surface. The cutting insert includes an out of round engagement surface that is pressed against an out of round shoulder surface to rotationally secure the cutting insert. The shoulder surface is included in a separate lock member that is partially inserted in a space formed in the basic body, the space opening towards the insert seat and located between the side support surface and the bottom surface of the insert seat such that the lock member rotationally secures a lower part of the cutting insert, while an upper part of the cutting insert is supported by the side support surface.
