Rotary tool attachment for edge material removal and fastener driving

A rotary tool attachment comprising:

• a proximal drive interface configured for engagement with a powered rotary driver;
• an elongate body extending distally from the proximal drive interface along a longitudinal axis;
• a distal bit-holding portion configured to receive or retain a removable driver bit;
• and
• a material-removal region disposed along at least a portion of an outer surface of the elongate body between the proximal drive interface and the distal bit-holding portion,
• wherein the material-removal region is configured to remove material from a surface region of a workpiece by rotational contact between the outer surface of the elongate body and the workpiece, including lateral engagement of the material-removal region with an edge, corner, or boundary region of the workpiece;
• wherein the distal bit-holding portion is positioned relative to the material-removal region such that the removable driver bit extends distally beyond at least a portion of the material-removal region;
• and
• wherein the rotary tool attachment is configured such that both (i) the material-removal region and (ii) the distal bit-holding portion with the removable driver bit remain simultaneously accessible and operable for material-removal and
• fastener-driving operations while the rotary tool attachment remains mounted to the powered rotary driver, without requiring removal, repositioning, or reconfiguration of the rotary tool attachment between such operations.
