Tube-cut′ter.

A device for cutting gas and other metallic pipes. The example (Fig. 6730) has a fixed jaw which grasps the pipe, and a slider which carries a rotary circular cutter and is advanced by a screw, while the instrument is turned about the pipe by means of its handle. See also pipe-cutter, page 1711.

Fig. 6731 is a special tool for cutting off boiler-tubes when their exterior cannot be reached. The lower end of the stock is inserted into the tube; the tool projects radially from the revolving-stock and cuts off the boiler-tube from the inside.
