How to use

Select the correct tap or die for the target metric size and secure it in the appropriate holder. For internal threads, lubricate the tap and start cutting slowly, ensuring the tap is perpendicular to the workpiece and advancing with steady forward motion and occasional reverse turns to clear chips. For external threads, mount the workpiece or die in its holder, apply suitable cutting fluid, and rotate the die evenly while maintaining straight alignment. After cutting, remove chips and inspect the thread for correct pitch, fit and surface condition.

Usage recommendations

Use cutting lubricant appropriate for the workpiece material to extend tool life and improve thread finish. Apply light, consistent pressure; avoid forcing the tool to prevent breakage. Clean tools and store them in the case after use to maintain organization and protect edges.
