PURPOSE: A pipe cutting tool is provided to stably supply a pipe at a right position by inside and outside machining bites regardless of the length of the pipe so that inner and outer sides of a front end portion of the pipe is precisely rounded or tapered. CONSTITUTION: A pipe cutting tool comprises a cylinder-shaped headstock(1), an inside machining bite(2), an outside machining bite(2'), and a tail rod(4). An inside machining bite mounting groove(11) and an outside machining bite mounting groove(12) are symmetrically formed in the outer circumference of the headstock at a predetermined depth. The inside and outside machining bites are inserted into the inside and outside bite mounting grooves and fixed by a bolt(3). Cutting end edges(22) of the inside and outside machining bites are projected to one side of the headstock at a predetermined length. Motor connecting shaft(13) is mounted in the other side of the headstock. The tail rod is mounted in a center of one side of the headstock and a plurality of rotary bearings(5) is installed in the outer circumference of the tail rod.
