Abstract
An improved tube cutter is provided for cutting off a tube section formed by two concentric tubes mechanically bulged together wherein the cut to be made is adjacent the bulged area. The tube cutter includes an elongated housing formed by two matable portions having longitudinal matching recesses which define an axial bore through the housing and transverse matching recesses which define a circumferential groove that accommodates the bulged area when the housing portions are clamped together about the tube section. Each of the housing portions carry a cutter bit which is located adjacent the groove and is extendable into the axial bore as the tube cutter manually rotated about the tube section so as to make a cut through the tube section adjacent the bulged area.
