  • PENTAGON-SHAPED CUTTING INSERT AND SLOTTING CUTTER THEREFOR
    Publication number: 20140294524
    Abstract: A cutting insert for machining a workpiece includes a top surface; a bottom surface. A plurality of peripheral side surfaces extend between the top and bottom surfaces. Each side surface includes an arcuate-shaped surface and a substantially planar surface. Each substantially planar surface is formed with a true angle with respect to a plane perpendicular to the top and bottom surfaces that results in a relatively smaller resultant angle when mounted in a slotting cutter to produce a true 90 degree wall on a workpiece during a slotting cutting operation.
