A cutting tool for severing the end of a copper tube or the like, the tool having a cylindrical post for insertion into the tube end, and a pivotal beam having a cutter wheel mounted at one end. A rotatable knob is mechanically linked to the pivotal beam to cause it to pivot toward and away from the cylindrical post. The entire tool may be rotated about the axis of the tube while the cutter wheel is in contact with the tube to cut a circumferential groove into the tube and thereby to sever the tube.
