ABSTRACT:
This application describes a dental burr including a cutting surface having one or more grooves therein, each of the grooves being defined by a plane which encircles the cutting surface at a skewed angle with respect to the axis of rotation of the burr. Such groove(s) provide an oscillatory chip clearing action as the burr rotates to give edge cutting and fast chip clearance. The cutting surface has abrasive particles coated thereon.
