Lenox recently came out with a new tight spaces tubing cutter design. These compact c-shaped cutters feature stainless steel rollers and an optimized shock-resistant blade geometry for less burrs and more cuts.
These new cutters can be used on copper, brass, and aluminum tubes, and are available in individual 1/2″, 3/4″, and 1″ sizes, or as part of a 3 piece kit. The cutting blades are user-replaceable.
