Abstract
A cutting insert of hard wear resistant material which provides a cutting edge useful over very wide ranges of metalworking conditions and effective for reducing cutting machine power requirements and providing safe and efficient chip control, simultaneously. The cutting insert has a narrow land area along the cutting edge and a wall means leading downwardly and inwardly from the inner edge of the land area and a planar surface extending inwardly from the lower edge of the wall means. The insert is free of any 'chip groove,' having a rising rearward wall, per se, and dimensions are given wherein it has been found that chip formation and breakage occur as naturally as possible with a minimum of work effort input for bending or breaking the chip. Power consumption is reduced and individual chip formations are controllable over a wider range of work conditions than heretofore possible.
