Abstract
An improved cutting insert for threading applications has chip control features and includes an insert body having end wall regions, sides and top and bottom walls adapted for mounting in a pocket in a holder. The insert body has cutting edges and a notch in the top and bottom sides. The end wall regions each comprise two end walls converging toward one another as they extend from the insert's sides, forming at the juncture with the respective top and bottom walls, a cutting edge. The chip control geometry including a recess defining, when viewed in plan, a generally "V" shaped depression having the bottom of the "V" proximate the tip of the cutting edge. The extending arms of the "V" are distal the cutting edge tip and are crowned by a pair of backramps.
