Cutting tool having replaceable cutting tip, a replaceable cutting tip therefore and a method of securing a replaceable cutting tip

Abstract

A rotary cutting tool includes a cutting tip having a cutting portion adapted to perform cutting operations on a workpiece and a threaded aperture defined therein generally opposite the cutting portion. The cutting tool further includes a generally cylindrical tool body disposed about a central longitudinal axis, the tool body having a first end portion adapted to be coupled to a machine tool and an opposite second end portion including an aperture having a coupling mechanism disposed therein. The coupling mechanism includes a first threaded portion cooperatively engaged to the threaded aperture of the cutting tip. The first threaded portion is moveable with respect to the tool body in a manner that selectively couples the cutting tip to the tool body.
