Abstract

A cutting tool including an annular cutter body having at least one V-shaped pocket formed therein and a cutting tool cartridge configured to be received in the at least one pocket of the cutter body. The cutting tool cartridge including a main body. The main body includes a cutting head having a cutting chip control portion and a pocket configured to receive a cutting insert.

Claims

1. A cutting tool, comprising:

a cutter body including at least one pocket formed therein; and

a cutting tool cartridge configured to be received in the at least one pocket of the cutter body, the cutting tool cartridge including a main body, wherein the main body includes a cutting head having a pocket configured to receive a cutting insert, wherein the pocket of the cutting head includes a shoulder and a recess formed between the shoulder and a substantially planar surface, wherein the shoulder and the substantially planar surface cooperate to position the cutting insert relative to the cutting tool cartridge, wherein the at least one pocket of the cutter body is a V-shaped pocket configured to receive one of a right handed cutting tool cartridge and a left handed cutting tool cartridge.

2. The cutting tool of claim 1, wherein the shoulder extends substantially parallel to a longitudinal axis of the main body.

3. The cutting tool of claim 1, wherein the shoulder is formed by a substantially planar first surface and a substantially planar second surface.

4. The cutting tool of claim 3, wherein a portion of one of the first surface and the second surface of the shoulder is angled with respect to a longitudinal axis of the main body.

5. The cutting tool of claim 1, wherein the cutting head includes a cutting chip control portion.

6. The cutting tool of claim 1, wherein the cutting insert includes at least one of first end and a second end, the second end having a nose radius, a wiper surface, and a relief surface.

7. The cutting tool of claim 1, wherein the cutting insert includes at least one of a substantially planar outer surface, a substantially planar first inner surface, and a substantially planar second inner surface.

8. The cutting tool cartridge of claim 1, wherein the cutting insert is formed from a polycrystalline diamond material.

9. The cutting tool cartridge of claim 1, wherein the cutting insert is secured to the cutting head.

10. The cutting tool cartridge of claim 1, wherein the cutting insert is secured to the cutting head by brazing.

11. A cutting tool, comprising:

a cutter body including at least one pocket formed therein; and

a cutting tool cartridge configured to be received in the at least one pocket of the cutter body, the cutting tool cartridge including a main body, wherein the main body includes a cutting head having a cutting chip control portion and a pocket configured to receive a cutting insert, wherein the pocket of the cutting head is defined by a shoulder formed by a substantially planar first surface and a substantially planar second surface, a clearance recess, and a substantially planar third surface, and wherein a portion of one of the first surface and the second surface of the shoulder is angled with respect to a longitudinal axis of the main body.

12. The cutting tool of claim 11, wherein the cutting insert includes a first end, a second end, a substantially planar outer surface extending between the first end and the second end, a substantially planar first inner surface, and a substantially planar second inner surface, and wherein the second inner surface is configured to cooperate with the angled portion of the second surface of the cutting head of the cutting tool cartridge.

13. The cutting tool cartridge of claim 11, wherein the cutting insert is formed from a polycrystalline diamond material.

14. The cutting tool cartridge of claim 11, wherein the cutting insert is secured to the cutting head.

15. The cutting tool cartridge of claim 11, wherein the cutting insert is secured to the cutting head by brazing.

16. A cutting tool cartridge, comprising:

a main body including a cutting head having a pocket configured to receive a cutting insert, wherein the pocket includes a shoulder and a recess formed between the shoulder and a substantially planar surface, wherein the shoulder and the substantially planar surface cooperate to position the cutting insert relative to the cutting tool cartridge, wherein the shoulder is formed by a substantially planar first surface and a substantially planar second surface, and wherein a portion of one of the first surface and the second surface of the shoulder is angled with respect to a longitudinal axis of the main body.

17. The cutting tool cartridge of claim 16, wherein the cutting insert is formed from a polycrystalline diamond material.

18. The cutting tool cartridge of claim 16, wherein the cutting insert is secured to the cutting head.

19. The cutting tool cartridge of claim 16, wherein the cutting insert is secured to the cutting head by brazing.

20. A cutting tool cartridge, comprising:

a main body including a cutting head having a pocket configured to receive a cutting insert, wherein the pocket includes a shoulder and a recess formed between the shoulder and a substantially planar surface to position the cutting insert relative to the cutting tool cartridge, wherein the substantially planar surface is substantially parallel to a central longitudinal axis of a cutter body in which the cutting tool cartridge is configured to be disposed, and wherein the main body has a generally triangular cross-sectional shape.
