ABSTRACT:
An indexable cutting insert for metal machining comprises an upper rake surface, a bottom surface and side surfaces that extend between the upper and bottom surfaces. Cutting edges are formed at the transitions between the side surfaces and the upper surface. Disposed along the cutting edges on the upper surface are elongated primary lands. Disposed inside of the lands is a chip-breaking depression. A raised land area to be ground is situated in the chip-breaker, so that the total grinding area of the upper surface becomes about as large as the total grinding area of the bottom surface. The insert can thus be ground by upper and lower grinding wheels which rotate simultaneously in opposite directions.
