Practical tips for best results:
- Lubricate with appropriate cutting oil to reduce heat and extend die life.

- Begin with a light pass to establish the thread, then increase pressure gradually until the desired depth is reached.
- Withdraw and clean chips regularly to prevent binding and ensure a smooth cut.
