1. An Apparatus comprising:
a low-power cutting tool for insertion into a pipe and configured to remove material from an internal surface of the pipe, the cutting tool comprising:
a housing for insertion within the pipe;
a cutting head extending from the housing and comprising a cutting tip for machining the internal surface of the pipe in a machining operation when the cutting tool is inserted into the pipe; and
one or more actuators for driving the cutting tip during the machining operation;
one or more processors; and
a computer-readable memory storing instructions which, when executed by the one or more processors:
control the one or more actuators to cause the cutting tip to machine the internal surface of the pipe to remove material therefrom in the machining operation, such that the cutting tool is maintained in a low-power configuration,
the low-power configuration being wherein an electrical power requirement is controlled not to exceed a predetermined electrical power threshold,
wherein, in the low-power configuration, an operational parameter of the one or more actuators is controlled to maintain the cutting tool in the low-power configuration, and
wherein the operational parameter being indicative of a movement of the cutting tip.
