SNAP RING PLIERS - HP TRU-99

Also known as snap rings, retaining rings or circlips, Truarc Rings are found on lock cylinders and other mechanical assemblies and are available in two formats, internal and external. To remove or install these rings you need a compressing tool to reduce the diameter of internal rings and a spreading tool to enlarge the diameter of external rings. Whether the ring is an internal or external, as well as the size of the ring and the size of the holes will depend on the application. The best pliers will accommodate both internal and external rings in a wide range of sizes and have multiple tips for the various hole diameters.
