Abstract
Described herein is a reamer tool () having a body () with bays () in which cutter arms () are mounted for deployment between a stowed position and a deployed position. A deployment mechanism is provided for deploying the cutter arms from their stowed position to their deployed position that maintains each cutter arm in a position that is substantially parallel to a longitudinal axis of the body () whilst in its stowed position and in its deployed position as well as during its deployment from its stowed position to its deployed position. A control module () is also described for controlling the deployment of the cutter arms (). The control module () comprises a motor (), a gearing mechanism () and a moveable element () that closes a port () in a first position and opens the port () in a second position. Fluid flow enters a chamber () behind a piston () through the port () to allow pressure to build up before actuating the piston () and thereby the deployment mechanism for the cutter arms ().
