Pipe grooving tools form slots in pipe so it can be clamped together instead of welded. Roll groovers press their rollers around the edge of pipe to create a slot for connecting two lengths with a grooved coupling. Roll sets, diameter tape, and tool boxes replace worn rollers that no longer form grooves or change rollers to groove different pipe sizes and materials, measure grooves to check for a proper fit with grooved couplings, or store and transport extra roller sets and replacement parts for roll groovers.
