LENOX 21012-TC13/4 Tubing Cutters will cut pipe diameters from 1/8" to 1-3/4". The four roller tracking systems keeps the tube from threading. The full-stop feed systems prevents the wheels and rolers from coming into contact. The wheels are quick and easy to change with only a screwdriver with extra cutting wheels stored in the handle. Cleanly and easily deburr pipes with the replaceable machinist's reamer. Ergonimically designed for a professional performance.
