The 4-roller tracking system keeps the cutter from walking across the tube surface so it cuts cleanly instead of threading. Cleanly and easily deburr pipes with the replaceable machinist's reamer. A full-stop feed system prevents wheels and rollers from coming into contact, so rollers don't damage wheels. Change out wheels quickly & easily. Store an extra cutting wheel in the handle. LENOX Tools Tubing Cutter, 1/8- to 5/8-inch (21008TC58).
