Abstract: A rotary cutting tool includes a replaceable cutting tip having a cutting portion structured to perform cutting operations on a workpiece and a first threaded portion disposed generally opposite the cutting portion. The cutting tool further includes a generally cylindrical tool body disposed about a central longitudinal axis. The tool body has a first end portion adapted to be coupled to a machine tool and an opposite second end portion having a second threaded portion cooperatively engaged to the first threaded portion. The second threaded portion is moveable with respect to the tool body in a manner that selectively couples the cutting tip to the tool body.
