A portable tube cutting apparatus which facilitates smooth, even cuts through a boiler tube-wall includes a frame supporting a movable carriage, a motor driven cutting tool secured to the carriage, and an articulated support means which allows for rotation of the cutting apparatus about a fixed point of securement to the boiler tube-wall and thereby permits lateral repositioning of the cutting apparatus relative to the point of securement to the boiler tube-wall. The apparatus has the advantage of permitting relatively long cuts such as up to about 3 feet to be made in a tube-wall While reducing the amount of time and effort needed to install and set up such apparatus relative to conventional track mounted apparatuses.
