Abstract
Apparatus for removing a burr from an edge of a workpiece comprising a rotating shaft, an abrasive mechanism along a distal end portion of the shaft, and a non-abrasive collar provided along the abrasive mechanism. The non-abrasive collar protects the wall of the workpiece from unintentional abrasion while the rotating abrasive mechanism is advanced into position for deburring. A proximal end of the rotating shaft may be attached to a flexible coupling member for allowing the shaft to deflect when a lateral force is exerted on the apparatus by the wall of the workpiece. The cross-sectional shape of the abrasive mechanism may be curvilinear and/or polygonal, depending upon the shape of the edge to be deburred. Two or more different abrasive mechanisms and/or non-abrasive collars can be simultaneously attached to the shaft.
