ABSTRACT:
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.
