Abstract
A tool for removing burrs/flash from a work piece includes a linear body having a cutter/abrasive end and an opposite shank end. The shank end is adapted for attachment to a rotary power source. At least one bushing is secured to the linear body, the bushing allowing rotation of the tool there within while an outer portion of the bushing remains stationary.

DESCRIPTION OF THE EMBODIMENTS
Nomenclature
[0021] 10 Burr/Flash Removal Tool [0022] 12 Linear Body [0023] 14 Cutter/Abrasive Section [0024] 16 Shank End [0025] 18 Cutting Edges [0026] 20 Bushing/Bearing [0027] 22 Bushing/Bearing Inner Portion [0028] 24 Bushing/Bearing Outer Portion
Construction
[0029] The invention is a tool for removing burrs/flash from a work piece. The tool 10 comprises a linear body 12 including a cutter/abrasive section 14 and at least one shank end 16. The at least one shank end 16 is adapted for attachment to a rotary power source. At least one bearing/bushing 20 is secured to the linear body 12, the bearing/bushing 20 allowing rotation of the tool there within while the outer portion of the bearing/bushing 20 remains stationary. Preferably, the tool 10 includes two bearings/bushings 20 secured at selected locations on the tool 10.
[0030] Referring now to FIG. 1, a first embodiment of the burr removing tool 10 is shown. The tool includes a linear body 12 with a cutter/abrasive end 14 and an opposite shank end 16. The shank end 16 is adapted for attachment to a rotary power source (not shown), such as a die grinder/power drill. The cutter/abrasive end 14 includes multiple cutting edges 18 which are used to remove flash/burrs and other imperfections on the surface of the work piece. At least one bearing/bushing 20 is secured to the linear body 12, allowing rotation of the linear body 12 there within, while the outer portion 24 of the bearing/bushing 20 is stationary. Thus, the operator can rest the bearing/bushing 20 on the work piece while the cutter/abrasive portion 14 of the tool 12 rotates to remove burrs/flash or other imperfections on the work piece. The ability of the operator to rest the bearing/bushing 20 or bearings/bushings 20 on the work piece greatly improves the control of the cutter/abrasive section 14 when removing flash/burrs or other imperfections.
[0031] FIG. 2 provides a cross sectional view of the flash/burr removing tool 10 along line A-A of FIG. 1. Note the location of the multiple cutting edges 18.
[0032] Referring now to FIG. 3, a second embodiment of the burr/flash removing tool 10 is shown. The tool 10 includes a linear body 12 with a cutter/abrasive end 14 and an opposite shank end 16. The shank end 16 is adapted for attachment to a rotary power source (not shown), such as a die grinder/power drill. The cutter/abrasive end 14 includes multiple cutting edges 18 which are used to remove burrs/flash and other imperfections on the surface of the work piece. At least one bearing/bushing 20 is secured to the linear body 10, allowing rotation of the tool 10 there within, while the outer portion 24 of the bearing/bushing 20 is stationary. In the embodiment of FIG. 3, the tool 10 includes two bearings/bushings 20, one bearing/bushing 10 at each end of the cutter/abrasive end 14 with the bearing/bushings 20 extending slightly beyond the cutter abrasive surface. FIG. 4 provides a cross sectional view of the tool along line B-B of FIG. 3.
[0033] Referring now to FIG. 5, a third embodiment of the burr removal tool 10 is shown. The tool includes a linear body 12 with a cutter/abrasive section 14 and opposed shank ends 12, one at each end of the cutter/abrasive section 14. FIG. 6 shows the burr/flash removal tool 10 with multiple bearings/bushings 20 secured thereto. In this third embodiment, removal of one of the bearings/bushings 20 would be required to allow attachment of one shank end 12 to a rotary power source (not shown). The bushings will normally spin on the outside diameter while reducing friction and eliminating or reducing damage to the surface of the work piece.
[0034] FIGS. 7 and 8 provide multiple perspective views of a similar burr/flash removal tool 10 with multiple bearing/bushings 20 secured thereto.
[0035] While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
