    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

    Abstract: An improved flaring tool includes the usual plurality of expandable die blocks retained by a U-shaped frame. A clamping screw is treaded through a clamp block which is rotatably mounted between the legs of the frame at its open end. The screw is movable toward and away from the die blocks to clamp or unclamp tubing between adjacent die blocks. A conical flaring tip is movable against the end of a clamped tubing for flaring same. The clamp block's axis of rotation is perpendicular to the direction of movement of the die blocks and the screw. The improvement comprises a facility which locks the clamp block against rotation when the screw is aligned with the die block and their direction of movement. The locking facility prevents unintentional rotation of the clamp block as the screw is rotated to clamp or unclamp the tubing, but may be manually overcome to intentionally rotate the clamp block.
