Abstract
An apparatus for performing a milling operation includes a mill having an internal fluid conduit and a fluid port configured to connect the internal fluid conduit to an exterior of the mill. A moveable flow diversion component is configured to move axially in the internal conduit from a first axial position in which fluid is prevented from flowing between the internal fluid conduit and the fluid port, to a second axial position in which the internal fluid conduit is in fluid communication with the fluid port. The apparatus also includes one or more slots configured to engage one or more pins extending into the internal fluid conduit, the one or more slots defining a path that directs movement of the flow diversion component. The flow diversion component is configured to be moved from the first to the second axial position by changing fluid pressure in the internal fluid conduit.
