The RIDGID 101 (40617) Close Quarters Tubing Cutter is specifically designed for use in restricted spaces on small diameter, hard and soft copper, aluminum, and brass tubing. The cutter features strong, lightweight slide and wheel housing, and a large knurled feed screw knob, which both combine to provide easy control of cutting pressure for clean cuts. In addition, the rollers include grooves for close-to-flare cuts, while the special knob allows for easier tightening of the feedscrew.
