Abstract
A cutting tool includes an elongate main body having inlet and outlet ends with a fluid flow path defined therebetween. A piston is mounted within the main body and longitudinally movable with respect to the main body. One or more cutters are moveable between retracted and deployed positions. The piston and each cutter engage one another so that longitudinal movement of the piston with respect to the main body moves each cutter between the deployed position and the retracted position. A flow regulator is operable to divert fluid flowing into the inlet end of the tool selectively along a first path, which passes the through the piston to the outlet end of the tool, and a second path, in which the fluid tends to drive the piston longitudinally with respect to the main body.
