The Model 301 Tube Squaring Tool is designed specifically to prepare tubes for autogenous welding. The 301 will face (square) .125” (3.2mm) to 1.102” (28.0mm) outside diameter tubing with a wall thickness up to .125” (3.2mm). Speed control is provided with a variable speed electric drive, or a pneumatic drive motor. Feed is provided by a cam actuated feed handle at right angles to the cutter head. The 301 uses OD clamping Collets which hold and round the tubing and provide torque acceptance of the Tool. The clamping collets on the standard system are retained by a collet nut assy w/guard. A Quick Lock clamping system is available for increased productivity with the 301 Tube Squaring Tool.
