Abstract

An outer diameter deburring tool for deburring a tubing with an outer diameter. The outer diameter deburring tool, includes: a plunger button assembly; an adapter handle, the adapter handle accepting the plunger button assembly; an outer diameter cutter for deburring the outer diameter of the tubing, the outer diameter cutter communicating with the adapter handle; and, a plunger stem assembly, the plunger button assembly communicating with the plunger stem assembly such that the plunger button assembly being able to change the position of the plunger stem assembly, the plunger stem assembly being able to prevent burrs from entering the tubing while the outer diameter cutter removes burrs from the outer diameter of the tubing.

Claims

1. A manual outer diameter deburring tool for deburring a tubing, said tubing having an outer diameter, the outer diameter deburring tool comprising:

(a) a plunger button assembly, the plunger button assembly comprises of a plunger button disk, a plunger button spring and a cylindrical shaft, the cylindrical shaft comprising of a cylindrical shaft first end and a cylindrical shaft second end, the plunger button disk disposed at the cylindrical shaft first end and the plunger button spring disposed at the cylindrical shaft second end;

(b) an adapter handle, the adapter handle coaxially accepting the plunger button spring and the cylindrical shaft second end;

(c) an outer diameter cutter for deburring said outer diameter of said tubing, the outer diameter cutter rotatably and coaxially attached to the adapter handle, the outer diameter cutter being a rounded cutting tool; and

,

(d) a plunger stem assembly, the plunger stem assembly comprises of a plunger stem stopper and a plunger stem assembly shaft, the plunger stem stopper attached to an end of the plunger stem assembly shaft, the adapter handle coaxially accepting the plunger stem assembly shaft, the plunger button spring and the cylindrical shaft coaxially associated with the plunger stem assembly shaft such that when applying pressure on the plunger button disk the plunger button disk can change the position of the plunger stem stopper via the cylindrical shaft and plunger button spring, the plunger stem stopper being able to prevent burrs from entering said tubing while the outer diameter cutter removes burrs from said outer diameter of said tubing.

2. The outer diameter deburring tool of claim 1, wherein the adapter handle is cylindrical.

3. The outer diameter deburring tool of claim 2, wherein the adapter handle having an adapter handle opening and counterbore, the plunger stem assembly entering the adapter handle opening and counterbore such that the plunger button assembly communicates with the plunger stem assembly.

4. The outer diameter deburring tool of claim 3, wherein the plunger stem assembly screws into the plunger stem assembly.

5. The outer diameter deburring tool of claim 4, wherein the adapter handle further comprising of an adapter handle main portion and an adapter handle neck, the adapter handle main portion containing the counterbore and the adapter handle neck containing the adapter handle opening, the adapter handle main portion and the adapter handle neck being cylindrically shaped, the adapter handle main portion having a larger diameter than the adapter handle neck, the plunger stem assembly entering the adapter handle opening, the plunger button assembly entering the counterbore.

6. The outer diameter deburring tool of claim 5, wherein the adapter handle main portion comprises of a adapter handle main portion outer surface, the adapter handle main portion outer surface being knurled.

7. The outer diameter deburring tool of claim 6, wherein the outer diameter cutter is manufactured from carbide.

8. The outer diameter deburring tool of claim 7, wherein the adapter handle main portion, the adapter handle neck, the plunger button assembly and plunger stem assembly being axially aligned.

9. The outer diameter deburring tool of claim 8, wherein the outer diameter cutter includes an inner diameter, the outer diameter cutter having a series of cutter tools at various angles, the series of cutter tools of various angles being located at the inner diameter of the outer diameter cutter such that the series of cutter tools can deburr the outer diameter of said tubing.

10. The outer diameter deburring tool of claim 9, wherein the outer diameter cutter has a cutter hole.

11. The outer diameter deburring tool of claim 10, wherein the plunger stem stopper and outer diameter cutter are interchangeable to allow different size tubing to be deburred.

12. The outer diameter deburring tool of claim 11, wherein the adapter handle main portion includes a counterbore lip, the counter bore lip closes around the adapter handle opening, the plunger button spring resting on the counterbore lip.

13. The outer diameter deburring tool of claim 12, wherein the cutter tools are a series of cutter teeth.
