Gene, I frequently use a boring bar with a threading insert to thread mill threads. It is a one flute thread mill but it does a wonderful job and is not expensive. You can cut OD and ID threads. Works a treat. If your mill doesn't have a spiral code then maybe your CAM package can output the motion in plain gcode. thanks Stuart
