Husky's 1/2 in. Automatic Tube Cutter makes cutting copper tubes easy and intuitive. The spring-loaded cutter wheel tightens while turning to maintain constant pressure, resulting in cleaner cuts. The hardened steel wheel and lightweight plastic body makes cutting smoother. The Automatic Tube Cutter has 1/2 in. maximum nominal pipe capacity (5/8 in. outer diameter). Husky's 5/8 in. Junior Tube Cutter can trim 1/8 in. to 5/8 in. outer diameter (1/4 in. to 1/2 in. NPS) tubing quickly and with little effort. The knob has a spoked design for added leverage and turning ease. It provides clean, square cuts on copper, brass, aluminum and thin-wall conduit, especially in tight spaces. This heavy-duty cutter is the perfect addition to your toolbox. Built to last and backed by the Husky lifetime warranty.
