A tool feed module (10) for a portable lathe machine tool includes a tool block (32) carrying a cutting tool (38) driven by a feed screw (50) incrementally advanced during a cutting procedure by an actuator arm (26) contacting a striker device (20) located on the tool housing. The actuator arm drives the feed screw through an actuator shaft (60) and a one-way drive device (46) permits the actuator arm to pivot in opposite directions while driving the feed screw in increments during pivotal motion in a single direction. |
