1. A device for performing a mechanical operation on a wireline, the device comprising:
a motor;
a gear train coupled to the motor, the gear train including a first rotational output and a second rotational output, the first rotational output and the second rotational output having different rotational speeds relative to each other;
a fluid pump coupled to both the first rotational output and the second rotational output of the gear train, the fluid pump comprising:
a pump housing coupled to the first rotational output of the gear train, and
a pump input coupled to the second rotational output of the gear train; and
a milling bailer coupled to the housing of the fluid pump and configured to rotate with the fluid pump housing, the milling bailer comprising:
a bailer portion shaped to intake fluid proximate a distal end of the bailer portion and allow the fluid to flow through a filter and through the fluid pump; and
a milling face proximate the distal end of the bailer portion, the milling face comprising at least one bit for milling and configured to perform a milling operation while the fluid is flowing through the bailer portion.
