A cutting tool has at least one insert receiving pocket with a cutting insert retained therein. The insert receiving pocket has a base wall and a side wall transversely directed to the base wall with a circular recess having a peripheral wall extending downwardly from the base wall. A threaded bore extends downwardly from the lower wall of the recess. The cutting insert has an upper surface, a lower surface and a cylindrical protrusion having peripheral surface extending downwardly from the lower surface. A through bore extends through the cutting insert from the upper surface. A retaining screw passes through the through bore and threadingly engages the threaded bore with the peripheral surface abutting the peripheral wall and with the lower surface abutting the base wall. |
