Tool for fine machining boring surfaces

摘要

A cutter insert for a tool for the finish machining by chip removal of bore surfaces in workpieces is proposed, the cutter insert being inserted in a recess introduced into the peripheral surface of the tool and being held by means of at least one clamping shoe which interacts by means of a clamping lip with at least one clamping surface of the cutter insert, which is distinguished by the fact that the cutter insert, which preferably has a substantially rectangular configuration, has a hypothetical center line (39) with which the clamping surface (21; 21') encloses an acute angle (alpha; alpha').
