Abstract
A flat disk-like tool insert has a plurality of arcuate cutter tips for machining the side surface of a rotating work piece, and a plurality of linear cutting edges for machining a chamfer on the end of the work piece. An endless land surface is contiguous with the cutter tips and the linear cutting edges so as to deflect metal chips away from the machined surfaces. Each tool tip is aligned with two chip breaker ledges that are arranged in a step configuration, such that chips of varying thickness can be effectively and cleanly broken without interference with the machining process. A third chip breaker ledge is set back from each linear cutting edge for breaking chips generated during a chamfering operation.
