<p>In a first aspect, the invention relates to a tool intended for chip removing machining, which comprises a basic body (1) and a replaceable cutting insert (5) that is detachably mounted in an insert seat (4) formed in the basic body, which seat is delimited by a bottom surface (10) and at least one side support surface (11), the cutting insert including an out of round engagement surface (22) that is pressed against a likewise out of round shoulder surface (29) formed on a separate lock member (24) that is inserted in a space (36) formed in the basic body, which space opens towards the insert seat (4) and is located between the bottom surface (10) and the side surface thereof in order for the lock member to rotationally secure a bottom portion of the cutting insert, while an upper portion thereof is supported against the side support surface. By the fact that the shoulder surfaces (29) are formed on a separate lock member, the manufacture of the tool is facilitated, in particular when the cutting inserts are numerous, small and round.</p><p><Paragraphs id="pa02" num="0002" xmlns:base="http://www.sipo.gov.cn/XMLSchema/base">Furthermore, the invention relates to a tool basic body and a lock member as such.
