A positive feed tool having a retract valve. The retract valve is manually actuatable so as to cause an advancing spindle of the tool to retract away from a workpiece. The retract valve is configured to automatically return its unactuated position after the retract valve is manually actuated so as to cause the spindle to once again advance toward the workpiece.
