Reed's TC50SLR is a C Cutter. It has a 1/2" capacity. This easy-to-grip cutter easily snaps on to copper tubing for a quick, clean cut. You simply turn the cutter in the direction of the arrow and the cut will be complete in seconds. The spring-loaded cutter wheel self-feeds on Type K, L, and M copper and CTS CPVC with consistent pressure as the tool is turned around the tubing. Each cutter fits just one popular size of copper tubing.
