1. A hydraulic tool for working on a workpiece, the hydraulic tool comprising:
a housing configured to be held by an operator;
a motor positioned in the housing;
a battery supported by the housing and operable to supply power to the motor;
a drive mechanism supported by the housing, the drive mechanisms comprising a cylinder, a piston moveably supported in the cylinder, and a pump powered by the motor and operable to supply hydraulic fluid to the cylinder to move the piston relative to the cylinder;
a jaw member supported by the housing and configured to engage with the workpiece; and
a spindle operatively coupled to the drive mechanism such that operating the drive mechanism moves the spindle in an axial direction to move part of the workpiece in the axial direction relative to the jaw member to work on the workpiece.
