    THREAD CUTTING CAUTION： ： ： ： DO NOT RUN SPINDLE IN REVERSE WHEN THREADING. The SHARP 1118H is designed for rapid and accurate thread cutting. The quick-change gearbox permits instant selection of 36 different inch and metric threads. Threads can be cut to a shoulder without running into the shoulder since the automatic stop will limit carriage travel at a predetermined point in either direction.
