초록 ▼

An improved tool is described that has a generally cylindrical slotted shank with a radially bulbous or extending portion adjacent a distal end of the shank, sized to interfere with a bore in which the shank is to be inserted. The dimension of the extending portion can be sized to change the retention force between the shank and the bore as desired. A top of the tool includes a metal carbide-metal disk-metal carbide diamond coated tip sandwich that is bonded inside a bore in the top of the tool.

대표청구항 ▼

1. A tool comprising: a metal body comprising a top that includes a bore extending axially inwardly from the top;a shank depending from a bottom of the metal body;a metal carbide plug positioned wholly within said bore and bonded in the bore;a metal disk bonded to a top of the metal carbide plug; andan impact tip being bonded to a top of the metal disk, the impact tip extending outwardly of the top of the metal body. 2. The tool as defined in claim 1, wherein bonded includes brazing. 3. The tool as defined in claim 1, wherein the metal disk starts out as a metal plug extending outwardly of the top of the metal body. 4. The tool as defined in claim 1, wherein the metal disk has a coefficient of expansion that is greater than that of the metal carbide plug, thereby providing greater rigidity to said metal body when in use. 5. The tool as defined in claim 1, wherein the metal disk is heat treated after the metal disk is bonded to the top of the metal carbide plug. 6. The tool as defined in claim 1, wherein the metal (steel) disk forms a sandwich structure with the metal carbide plug immediately below the metal disk and a metal carbide base of the impact tip above the metal disk on the tool. 7. The tool of claim 1, further comprising: a metal carbide shield mounted to the top of the metal body. 8. A method of making the leading end of a tool body comprising the steps of: bonding a metal carbide plug wholly within a bore in a top of the tool body;bonding a metal plug to a top of the metal carbide plug in the bore;heat treating the top of the tool body;removing a portion of the metal plug from the tool body, thereby leaving a residual disk in the bore; andbonding an impact tip to a top of the residual disk with the tip extending outwardly of the top of the tool body. 9. The method of claim 8, wherein said heat treating is carried out at a higher first temperature than bonding the impact tip to the top of the metal plug, wherein the bonding of the impact tip is carried out at a second temperature lower than the higher first temperature. 10. The method of claim 8, further comprising the step of: cooling said tool body to a temperature below that which would cause harm to a diamond impregnated material on the impact tip after the step of heat treating the top of the tool body. 11. The method of claim 8, further comprising: mounting a metal carbide shield to said top of the tool body before bonding the metal carbide plug in the bore in said top of the tool body. 12. A method of making the leading end of a tool body comprising the steps of: bonding a metal carbide plug wholly within a bore in a top of the tool body;bonding a metal plug to a top of the metal carbide plug in the bore;heat treating the top of the tool body;removing a portion of the metal plug from the tool body after heat treating the top of the tool body, thereby leaving a residual disk bonding an impact tip to a top of the residual disk with the tip extending outwardly of the top of the tool body. 13. The method of claim 12, wherein said bonding of at least one of the metal carbide plug, the metal plug, and the impact tip comprises brazing. 14. The method of claim 12, wherein removing comprises boring. 15. The method of claim 12, wherein removing comprises drilling. 16. The method of claim 12, wherein removing comprises cutting. 17. The method of claim 12 wherein said heat treating is carried out at a higher first temperature than bonding the impact tip to the top of the metal plug, wherein the bonding of the impact tip is carried out at a second temperature lower than the higher first temperature. 18. The method of claim 12 further comprising the step of: cooling said tool body to a temperature below that which would cause harm to a diamond impregnated material on the impact tip of the step of heat treating the top of the tool body. 19. The method of claim 12 further comprising: mounting a metal carbide shield to said top of the tool body before bonding the metal carbide plug in the bore in said top of the tool body.
