A rotary pipe cutter severs copper tube by progressive circumferential deformation rather than by material removal: a hardened wheel is pressed radially against the tube wall and orbited around it, so each revolution deepens the score until the wall parts, yielding a cut square to the tube axis. Spring-loaded cutters apply that radial force automatically and maintain it as the kerf deepens, removing the manual re-tightening step and reducing the swept envelope, which is what makes them usable in confined access. The operation belongs to plumbing and pipefitting within building services, and its necessary complement is deburring — the same rolling action work-hardens and displaces metal into an internal burr and raised external edge, which must be removed so bore diameter, flow, and joint sealing surfaces are not compromised.
