1. Drill the core hole: Use the correct tapping drill size from the UNC table. Ensure sufficient depth for the thread.
2. Deburr the hole: A slight chamfer improves tool alignment and thread start quality.
3. Clamp the tool: Insert the tap securely into a Tay quay taro.
4. Cut the thread: Apply steady pressure and rotate clockwise with clean alignment.
5. Use cutting oil: Proper lubrication improves cutting quality and tool life.
6. Finish the thread: Tap to full depth (for lỗ bít, do not exceed the bottom).
7. Check the thread: Verify with a matching screw or thread gauge.
