ABSTRACT:
A cutting tool has an insert holder provided with an insert receiving pocket and at least one cutting insert mounted therein. The insert receiving pocket has a longitudinally extending inner wall, a rear wall adjacent the inner wall and a lower wall adjacent the inner wall and the rear wall. A front end of the lower wall protrudes forwardly with respect to a central portion of the insert holder. A front protrusion rises upwardly from the lower wall and extends inwardly and rearwardly from a periphery of the insert holder. The front protrusion has a front surface perpendicular to the lower wall. A groove formed in the bottom surface of the cutting insert has a distal side wall perpendicular to the bottom surface. When assembled, a radial abutment surface of the cutting insert abuts a radial abutment surface of the insert receiving pocket, the front surface of the front protrusion abuts the front distal side wall of the groove and a rear portion of the one cutting insert is spaced from the rear wall of the insert receiving pocket.
