Give this a try:
1. Run your finish chamfer/turning tool.
2. Run the threading cycle, no spring passes required.
3. Call the finish chamfer/turning tool back up and run it again. This will remove the burrs from the o.d.
4. Last, run the threading cycle again. You can increase the depth of cut so that it those not take as many passes. This will remove the burrs that were kicked in from the turning tool.
This process may seem long, but it those not add much cycle time when done correctly. You will get a burr free thread every time.
