The lightweight, compact design and small diameter cutting heads of the Model 201BA BEVELMASTER permit rapid, accurate machining in tight spaces, making it perfect for boiler use. The OD mounting, (no mandrel) design clamps to the outside of tube or pipe allowing this machine to successfully work on boiler tubes with inside diameters under 1" with less damage than mandrel mounting systems. The machine features rapid clamping saddle adjustments and a right angle feed knob, with all controls (feed, clamp, motor) on the outside of the tube panel opening for safe and easy operation. The narrow width, of only 1.45" permits use on waterwall cutout windows and operate between boiler panels. The Model 201BA's adjustable saddles cover the full cutting size range.
