A cutting insert holder has a lower clamping jaw resiliently connected to an upper clamping jaw. The upper clamping jaw is provided with two elongated spaced apart parallel grooves. The cutting insert is retained in the cutting insert holder by means of a screw which passes through a through bore in the upper jaw of the insert holder, through a through bore in the cutting insert and is threadingly engaged into a threaded bore in the lower clamping jaw. The two elongated ridges in the upper surface of the cutting insert cooperate with the two elongated parallel grooves in the lower surface of the upper clamping jaw. |
