Abstract: A hand tool for cutting tubular workpieces such as copper tubing used for plumbing includes a rotary cutting head which has a slot for receiving a length of tubing to be cut, a gear drive mechanism for rotating the cutting head, and a clamping handle which supports the gear drive mechanism, which is rotatably driven by a battery powered electric motor. to thus rotate the cutting head to sever a length of tubing. The clamping handle includes a pair of longitudinally disposed, generally semi-cylindrically-shaped handle shells which are pivotable apart from one another to receive a length of tubing to be cut, and pivotable to a closed position and compressed in the palm of a workman's hand to press against and clamp the tool to a length of tubing being cut.

Abstract: A tool for cutting tubing includes a rotary cutting head which has a slot for receiving a tube to be cut, a gear drive mechanism for rotating the cutting head, a clamping handle which extends from the gear drive mechanism, and a pull cord drive wheel mechanism for rotating the gear drive mechanism which includes a pulley, a pull cord wrapped around the pulley, and a retractor spring to rotate the pulley in an opposite direction after it has been rotated in a first direction by pulling on the cord to thus rotate the cutting head to sever a length of tubing. The clamping handle includes a pair of opposed semi-cylindrically-shaped shells which are pivotable apart to receive a length of tubing to be cut, and pivotable to a closed position and compressed by hand pressure to grip the tubing being cut.

Abstract: A tubing cutter apparatus including a rotary cutting mechanism having an open area for receiving a length of tubing and a cutting blade for engaging the tubing may be driven by a rotary power source such as a handheld power tool or a self-contained drive motor. The apparatus includes a gear system for rotating the cutting mechanism about the tubing and a coupling mechanism for coupling the rotary power source to the gear system. A clamp comprising a slotted tubular plate spring protruding from a handle case of the apparatus in longitudinal alignment with the open area of the cutting mechanism enables the apparatus to clampingly engage a length of tubing to be cut by pushing flanged edge walls of the slot against the length of tubing, which may be in a location with limited accessability, such as within the wall of a structure.

Abstract: There is disclosed an improved tubing cutter apparatus which provides easier and faster modes of operation. It includes a rotary cutting mechanism having an open area for receiving a length of tubing and a cutting blade for engaging the tubing. It is suitable for use with a handheld power tool or may have a self contained driving element. A gear system is provided for causing rotation of the cutting mechanism about the tubing and included is a coupling mechanism for coupling the rotary driving element to the gear system for rotating the cutting mechanism.
