• Select the Correct Tool — Choose the tap or die that matches the desired thread size (SAE or Metric) and pitch. Use the included screw pitch gauge to confirm the thread specifications if unsure. Ensure the tool is clean and free of debris.
• Prepare the Workpiece — For cutting new threads, drill a pilot hole of the appropriate size. For chasing or repairing existing threads, clean the damaged area. Apply cutting oil to the tap or die to lubricate and cool the metal during the process.
• Apply Torque and Thread — Secure the tap or die in the appropriate wrench handle (tap wrench for taps, die handle for dies). Apply steady, even pressure and turn clockwise to cut threads. For taps, turn a full rotation, then back off a half-turn to clear chips. For dies, maintain consistent pressure.
• Clean and Maintain — After use, clean all tools thoroughly to remove metal filings and cutting oil. Dry them completely and apply a light coat of oil to prevent rust, especially in India's humid climate. Store them back in the tray case to keep them organized and protected.
