A tap and die set is designed for processing, correcting or cleaning external and internal threads, providing smooth and precise thread cutting operations. The threading tool sets are made from high hardness alloy steel, providing strong strength in re-threading hard materials like metal and creating new threads in soft materials such as plastic. The cutting teeth of the tap & die set are manufactured with precision CNC machining techniques and heat treated, ensuring precise dimensions and increasing hardness and sharpness, resulting in clean and accurate threads. The coating surface of metric tap and die set is wear resistant and rust resistant which can help to extend the service life. Tap and die kit comes with a storage case that keeps the tools organized and protected when not in use, and allows for easy access to the required tap or die. Note: Add suitable lubricating oil to the cutting edge of the die when tapping the thread.
