The tools are precision machined to produce accurate threads, ensuring a tight and secure fit when used to tap holes. Hand taps are mainly used with tap wrenches and are suitable for re-tapping damaged or stuck threads, or to create new threads. Used for tapping through or shallow holes in mild steels, aluminum, iron, copper, hard plastic. The straight groove design of the hand tap efficiently removes chips downward, reducing operational resistance and ensuring clear, burr-free threads for precise tapping. 6542 (M2) high speed steel tap set offers high hardness and excellent wear resistance for durability and longevity, and good cutting performance for clean, precise holes. Designed with basic structure without any coating, suitable for a wide range of applications. Tapping oil provides lubrication, cooling, and anti-sticking effects, enhancing the quality of internal threads and the durability of taps. After use, apply anti-rust oil for maintenance to extend the service life. Ensure proper alignment, use the correct tapping technique, and maintain consistent pressure for clean, precise threads. Periodically reverse the tap to break chips and clear debris.
