An extended sanding support tool, consistent with certain embodiments of the present invention has an elongated metal housing having first and second ends. A first bearing is coupled to the housing adjacent the first end and a second bearing is within the housing closer to the second end than the first end. A mandrel has a drill attachment end and a working end and passes through the first and possibly second bearings with the working end extending beyond the first end of the housing. In one embodiment, a cavity between the second end of the housing and the second bearing is provided for engaging a stationary portion such as a collar of an outer surface of a rotary tool housing an outer surface of a chuck of a rotary tool. In another embodiment a cone shaped structure receives the outer surface of the chuck. A cutting or sanding device is attached to the working end of the mandrel.

1. An extended sanding support tool, comprising:an elongated housing having first and second ends;a first bearing coupled to the housing adjacent the first end;a mandrel having length and having a drill attachment end and a working end passing through the first bearing with the working end extending beyond the first end of the housing;wherein, the housing is slideable along a portion of the length of the mandrel while the mandrel is coupled to a rotary tool, so that the housing selectively engages a portion of the rotary tool when the housing is slid along the mandrel toward the rotary tool in order to stabilize the housing, so that the user can selectively engage the housing with the rotary tool by sliding the housing toward the rotary tool and holding the housing in place; andmeans for attaching a cutting device or sanding device to the working end of the mandrel.2. The extended sanding support tool according to claim 1, wherein the housing has a cylindrical cavity adjacent the second end of the housing, and wherein the cylindrical cavity receives and engages a cylindrical collar adjacent a chuck of the rotary tool when the housing is slid toward the rotary tool, and wherein the cylindrical collar is stationary with respect to rotation of the rotary tool's chuck, so that the housing can be stabilized by holding the cylindrical cavity in engagement with the stationary cylindrical collar.3. The extended sanding support tool according to claim 1, wherein when the housing is slid along the mandrel away from the rotary tool, a chuck of the rotary tool is revealed.4. The extended sanding support tool according to claim 3, further comprising means for stopping the mandrel from sliding past the first bearing when the housing is slid away from the rotary tool to reveal the rotary tool's chuck.5. The extended sanding support tool according to claim 1, further comprising chuck receiving means for receiving an outer surface of a chuck of a rotary tool.6. The extended sanding support tool according to claim 5, wherein the chuck receiving means comprises a conical chuck receiving member that mates with a conical outer surface of the chuck of the rotary tool.7. The extended sanding support tool according to claim 6, wherein the second bearing comprises a dual bearing situated adjacent the second end, and wherein the conical chuck receiving member is mounted to the bearing such that the mandrel, the conical chuck receiving member and the housing can rotate independently of one another.8. The extended sanding support tool according to claim 1, further comprising a second bearing within the housing closer to the second end than the first end with the mandrel passing therethrough.9. The extended sanding support tool according to claim 1, wherein the means for attaching a cutting device to the working end of the mandrel comprises at least one of a chuck, a taper, a locking engagement mechanism, a screw thread, and a bore with set screws.10. The extended sanding support tool according to claim 1, wherein the housing is at least 12 inches in length, and wherein the second bearing is approximately 1 to 3 inches from the second end.11. The extended sanding support tool according to claim 1, wherein the mandrel is approximately ¼ to ⅝ inch in diameter.12. An extended sanding support tool, comprising:an approximately cylindrical elongated housing having first and second ends at openings of the cylinder;a first bearing coupled to the housing adjacent the first end;a mandrel having length and having a drill attachment end and a working end passing through the first bearing with the working end extending beyond the first end of the housing;an approximately cylindrical cavity between the second end of the housing and the second bearing for receiving a stationary portion of an outer surface of a rotary tool housing, the stationary portion of the outer surface of the rotary tool housing being adjacent a chuck of said rotary tool, and being stationary with respect to rotation of the chuck, and having a substantially circular cross-section;wherein, the housing is slideable along a portion of the length of the mandrel so that the approximately cylindrical cavity receives the stationary portion of the outer surface of the rotary tool housing when the housing is slid along the mandrel toward the rotary tool, and wherein when the housing is slid along the mandrel away from the rotary tool the chuck of the rotary tool is revealed; andmeans for attaching a cutting device or a sanding device to the working end of the mandrel.13. The extended sanding support tool according to claim 12, further comprising a second bearing within the housing closer to the second end than the first end with the mandrel passing therethrough.14. The extended sanding support tool according to claim 12, wherein the means for attaching a cutting device to the working end of the mandrel comprises at least one of a chuck, a taper, a locking engagement mechanism, a screw thread, and a bore with set screws.15. The extended sanding support tool according to claim 12, wherein the housing is at least 12 inches in length, and wherein the second bearing is approximately 1 to 3 inches from the second end.16. The extended sanding support tool according to claim 12, wherein the mandrel is approximately ¼ to ⅝ inch in diameter.17. An extended sanding support tool, comprising:an elongated cylindrical metal housing having first and second ends, the cylindrical metal housing defining an outermost boundary of the support tool between the first and second ends;a first bearing coupled to the housing adjacent the first end;a second bearing within the housing closer to the second end than the first end;a mandrel having length and having a drill attachment end and a working end passing through the first and second bearings with the working end extending beyond the first end of the housing;a cylindrical cavity between the second end of the housing and the second bearing for receiving and contacting a cylindrical stationary portion of an outer surface of a rotary tool housing, the cylindrical stationary portion being stationary with respect to a rotating portion of the rotary tool; andmeans for attaching a cutting device or a sanding device to the working end of the mandrel.18. The extended sanding support tool according to claim 17, wherein the means for attaching a cutting device to the working end of the mandrel comprises at least one of a chuck, a taper, a locking engagement mechanism, a screw thread, and a bore with set screws.19. The extended sanding support tool according to claim 17, wherein the housing is at least 12 inches in length, and wherein the second bearing is approximately 1 to 3 inches from the second end; and wherein the mandrel is approximately ¼ to ⅝ inch in diameter.20. The extended sanding support tool according to claim 17, wherein the cavity between the second end of the housing and the second bearing is adapted to receive a stationary collar connected to the rotary tool housing.21. The extended sanding support tool according to claim 17, wherein, the housing is slideable along a portion of the length of the mandrel so that the cylindrical cavity receives the stationary portion of the outer surface of the rotary tool housing when the housing is slid along the mandrel toward the rotary tool.22. The extended sanding support tool according to claim 21, wherein when the housing is slid along the mandrel away from the rotary tool, a chuck of the rotary tool is revealed.23. The extended sanding support tool according to claim 22, further comprising means for stopping the mandrel from sliding past the bearing when the housing is slid away from the rotary tool to reveal the chuck.
