ABSTRACT:
A tube cutter mechanism supports an arm from which a tube supporting anvil extends, the anvil being aligned with the tube cutter mechanism for cutting the supoorted tube. During cutting, an axial force is imposed on the tube and anvil. The arm is formed such that it bends in response to the force, storing energy such that rotation of the tube occurs for more than one revolution of the tube without advancing the cutter wheel. The device is formed of molded glass fiber reinforce nylon, preferably ZYTEL. In a second embodiment, the arm does not bend and the anvil is constructed so as to bend relative to the arm in response to the axial cutting force permitting rotation of the tube during cutting beyond a single revolution without advancing the cutter wheel. The anvil advantageously does not have a cutter wheel for burnishing the tube to remove oxides during cutting. In the alternative, the anvil may also have a pair of cutting wheels
