Abstract: A tube cutting tool is described in which a cutting head is rotatably mounted within a tool body wherein both define "O" shaped openings to enable tubing to be inserted perpendicularly through the tool. A cutting wheel is incorporated into the cutting head such that rotation of the cutting head causes the wheel to pass around the periphery of the tube. A feed cam and lever device are incorporated which mechanically bias the cutting wheel into contact with the tube wall until the tube wall has been completely severed. A gear drive assembly transports power from a power source to the cutting head to rotate it about the tube. Stabilizing devices are utilized to help secure and align the tubing into the cutting tool during operation.
