Step-by-Step Thread Cutting Guide
  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 tap wrench.
  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 blind holes, do not exceed the bottom).
  7. Check the thread: Verify with a matching screw or thread gauge.
