The 12 HSS hand tap is made from high-speed steel with high hardness and excellent resistance to wear and heat. Its length typically ranges from 60 to 90 millimeters, and its nominal diameter varies according to size number 12 in different standard systems. The square shank allows easy and secure fitting into a tap wrench. Precise flutes and thread geometry improve chip removal quality and reduce the required force during threading. The surface hardness usually ranges between 62 to 65 HRC, ensuring high tool durability.
This hand tap is suitable for creating high-precision internal threads in both soft and hard metal parts. The recommended manual operating speed is between 10 to 18 revolutions per minute to prevent overheating and tool damage. The pilot drill size is typically about 85 to 90 percent of the tap diameter. The 12 HSS tap is widely used in machining, industrial repair, and precision equipment manufacturing, delivering excellent thread quality.
