Quickly enlarge wax ring models and tubes with this tool.
Slide a wax ring model or ring tube onto this mandrel and rotate it against the steel blade. First enlarge one side, then turn the pattern or tube over to trim the other side. The blade shaves the inner circumference, enlarging wax rings and leaving an even, smooth finish. A size guide is printed on it but a proper sizing stick should be used to gauge the exact size once finished.
