Title: CUTTING INSERT HAVING TWO PERIPHERAL ABUTMENT RIDGES AND CUTTING TOOL
Abstract:
A cutting insert includes an insert longitudinal axis defining a forward to rear direction, opposing insert inner and outer side surfaces and an insert peripheral surface extending therebetween. The insert peripheral surface includes an insert rear end surface and an adjacent insert lower surface. The cutting insert includes two spaced apart peripheral abutment ridges that are distal the insert outer side surface and extend along the insert rear end surface and the insert lower surface, respectively. The two peripheral abutment ridges converge towards each other at an acute insert wedge angle in a rearward direction of the cutting insert, away from a cutting edge.
