The present disclosure provides a power tool including a housing and a hydraulic drive assembly at least partially supported in the housing. The housing includes a handle that supports a switch that activates the tool. The hydraulic drive assembly includes a pump assembly operably coupled to the motor assembly, a reservoir configured to contain hydraulic fluid in fluid communication with the pump assembly and in which a baffle is supported, a cylinder in fluid communication with the pump assembly which supports an auto-return valve therein, and a piston disposed in the cylinder and biased to a first position by a piston spring. The pump assembly includes a manifold housing that at least partially defines an inlet passageway that fluidly communicates the pump assembly and the cylinder and supports an inlet check valve.

A cable cutter includes stationary and moveable clamps, each comprising a respective pivot opening and a cutting edge spaced from the pivot opening. A pivot joint connects the clamps to allow the movable clamp to pivot about a pivot axis relative to the stationary clamp. The pivot joint includes a threaded connector having a head and a shank extending from the head along the pivot axis through the pivot openings in the clamps. A collar has opposing faces and an opening extending through the collar. A nut is threaded on the shank and the clamps are sandwiched between the head and the collar with the head adjacent one of the clamps. The collar is engaged to rotate with the shank the about the pivot axis.

A cutting tool includes a housing, a head assembly disposed on the housing and carrying a first blade. A cam drive mechanism is disposed within the housing. The cam drive mechanism carries a second blade opposed to the first blade. A motor drives the cam drive mechanism. A battery pack is electrically connected to the motor. The cam drive mechanism moves the second blade towards the first blade, so that a wire disposed between the first and second blades receives a cutting force of less than 12 kiloNewton. The cam drive mechanism may include a spindle driven by the motor, a radial cam fixed to the spindle, a roller assembly contacting the radial cam, and a shuttle connected to the roller assembly, the shuttle being movable in a reciprocating motion and carrying the second blade.
