Abstract (en)
The present invention provides a reamer 1 suitable for use in pipework 2 having at least two different internal diameters in a section thereof. The reamer 1 comprises an elongate body 4 formed and arranged for passing through a reduced diameter portion of said pipework 2 and has cutting member supports 6 with fixed pivotal mountings for a cutting member 8 for pivotal movement thereof between a retracted position and a deployed position extending radially outwardly of the body 4. The body 4 also has cutting member drive means 10 which engages part 22 of the cutting member 8 for displacement of the cutting member 8 between its retracted and deployed positions and substantially securely supporting the cutting member 8 in its deployed condition against angular displacement in the plane of pivotal movement about the pivotal mounting means. <IMAGE>
