  • Patent number: 4629372
    Abstract: A metal-cutting insert (10) having a cutting edge (31) and an associated chip control surface (52). Chip configuration control is effected by means of a cutting edge formed with a transverse rake face (52) extending to the top (64) of the insert above and behind the cutting edge (31) and a rearward extending channel (50) that penetrates both the top of the insert (64) and the shelf type cutting edge (31). Additional transverse shelves (62) are formed at spaced apart locations behind the cutting edge (31). The insert (10) can be ground back to the next rearward disposed shelf (62) forming a new cutting edge with an associated chip control configuration. The rake face (52) associated with a cutting edge (31) of the insert can be coated with a suitable material such as titanium nitride. The insert (10) after grinding will still have a coated rake face associated with the new cutting edge.
