How to use
- Secure the die in a die stock or holder designed for external threading; ensure it is oriented straight to avoid cross-threading.
- Lubricate the workpiece with an appropriate cutting fluid to reduce heat and extend die life.
- Position the die squarely on the rod or bolt and turn clockwise with steady, even pressure. Back off occasionally to clear chips and reapply lubricant.
- Continue until you’ve achieved the full thread length you need, then deburr the edge of the workpiece for safe handling.
Tips for best results: keep the workpiece well-lubricated, maintain a light to moderate cutting pace, and verify progress frequently to prevent misalignment. After use, clean any residue from the die and store in a dry place to maintain performance for future projects.
