A pipe cutting machine having a pair of parallel, horizontal driven rollers for supporting and rotating the work to be circumferentially cut. A cutter head assembly includes a free rotating cutter wheel on a shaft generally parallel to the driven rollers. Coarse vertical positioning of the cutter head is effected by sliding it up or down over a generally vertical support column. Detenting of this vertical positioning is effected by a spring-loaded pin engaging a selected groove among a plurality of vertically spaced, horizontally extending grooves associated with the vertical column. Vernier advancement of the cutter into the work is accomplished by an eccentric and lever arrangement associated with the cutter head assembly. A gear box arrangement couples the torque of a driving motor, which may be permanently or removably attached, providing drive to the rollers and to a reamer. A hand drill is shown positioned to provide motive power. A skewed-bore bushing supports a shaft connected to an operating lever for orienting the plane of the cutter wheel to provide adjustment compensating for manufacturing tolerances.
