Claims23
A blade for holding a cutting insert within a pocket of a toolholder, comprised of a blade body having:
- a) a blade first side and a blade second side which are generally parallel to and opposing each other and defining a width there between;
- b) a blade first end and a blade second end between the sides wherein the blade first side is suitable to receive and secure therein a cutting insert;
- c) a blade top wall and a blade bottom wall between the sides;
- d) wherein the blade bottom wall is comprised of a sloped flat extending downwardly from the blade first side toward the blade second side to form an acute angle BA with a line perpendicular to the second side;
- and
- e) wherein the blade second end is comprised of a canted flat extending inwardly and rearwardly from the blade first side toward the blade second side to form an acute angle BB with a line perpendicular to the blade second side;
- and
- f) a longitudinal slot for mounting the cutting insert therein extending from the blade first end toward the blade second end and defining an upper arm and a blade body base, the upper arm including an angled bore extending downwardly and rearwardly and aligned with a mating threaded bore in the blade body base for accepting a tightening bolt to clamp the upper arm against the cutting insert and securely retain the insert within the slot.
