The Ratch-Cut Ratcheting Tube Cutters, from Anglo American Tools, cut quickly and precisely through copper, brass, stainless steel, aluminum, plastic tubing, thinwall PVC and CPVC. Made from a aluminum-zinc alloy, rynite 530 and 545. The tool's small size, light weight and thin profile of the RATCH-CUT, coupled with its ratcheting mechanism, allows for working in very tight places. Durable replacement cutting wheels available.
