Abstract

A tool for chip-removing machining includes an insert holder, a cutting insert for chip-removing machining, and a fixing element for fixing the cutting insert in an insert seat of the insert holder. The insert has fingers projecting from a bottom side of the insert. The insert seat has a number of elastically flexible portions forming recesses therebetween which receive respective fingers of the insert. Contact surfaces of the fingers engage respective contact surfaces of the flexible portions to cause the flexible portions to flex elastically as the fingers become wedgingly secured in the recesses.
