1. A device for a selectable hole trimmer, the device comprising:
a body having a central mud feed line configured to receive a drilling fluid at a bore pressure;
an intermediate sleeve sealingly affixed inside the body via a stop block, the intermediate sleeve having a first activation port in fluid communication with a cutter piston of a selectable hole cutter;
a sliding sleeve sealingly slidable inside the intermediate sleeve to form a pressurized volume there between, the sliding sleeve having a second activation port configured to selectively align with the first activation port;
a radial compartment disposed in the body and fluidly connected to the central mud feed line via a drill string inlet, the radial compartment configured to house an actuator;
the actuator fluidly connected to the pressurized volume via a port, wherein the actuator is configured to selectively align the first activation port and the second activation port to provide a pressure to the selectable hole cutter and actuate a cutter piston of the selectable hole cutter to move relative to the body, wherein the cutter piston comprises one or more cutters; and
a controller configured to operate the actuator in response to a change of a monitored operation condition.
