Abstract
Provided is cutting tool. The tool, in certain examples, includes a drill body that defines a drill axis, and a tool window formed in the drill body. The tool also includes a drill bit extending from the drill body, and a material reworking attachment (“MRA”) coupled to the drill body and storable within the tool window. The MRA is extendable from a stored position into either a surface-finishing position or a material-removal position. The MRA includes a first chamfering blade, a second chamfering blade, and a finishing surface interposed between the chamfering blades. The tool also includes a position manager to detect a position of the cutting tool with reference to a workpiece, and an actuator to transition the MRA from the stored position to the material-removal position, followed by a transition to the surface-finishing position, and followed by a transition to material-removal position.
