STAR-TYPE INDEXABLE CUTTING INSERT AND TOOL SYSTEM
The invention relates to a tool system with a main part (1), a clamping element (2), and a cutting insert (3) for machining workpieces (7). The main part (1) has a recess (4), which forms an insert seat (25) for the cutting insert (3), in order to receive the cutting insert (3); the cutting insert (3) is secured in the insert seat (25) by the clamping element (2); and the cutting insert (3) has cutting edges (6a, 6b) on the circumferential surface (9) of the cutting insert. In order to substantially increase the adjustment angle (A) in the machining/advancing direction (20) towards the workpiece (7), shorten the engagement length of the cutting edge (6a, 6b) on the workpiece, and reduce the passive force (Fp) during the machining process, the circumference (9) of the cutting insert (3) is formed by protrusions (5) and recesses (16).
