Dolphin HSS M-2 Hand Tap, Size: 1/16 to 4 Inch, NPTF

The Dolphin HSS M-2 Hand Tap, available in sizes ranging from 1/16 inch to 4 inches, is specifically designed for tapping internal threads according to the National Pipe Taper Fuel (NPTF) standard. This type of hand tap is essential for creating precise tapered threads in pipes and fittings used in hydraulic and pneumatic systems, where a leak-resistant seal is critical.

Crafted from high-speed steel (HSS) grade M-2, the Dolphin HSS M-2 Hand Tap offers exceptional hardness, wear resistance, and heat tolerance, making it suitable for demanding threading operations in various materials including steel, stainless steel, brass, and other alloys commonly used in hydraulic and pneumatic applications.

The hand tap features a tapered design that matches the NPTF thread profile, which is similar to NPT but with modified thread dimensions to achieve a tighter seal. The tap's design ensures proper thread engagement and compression, minimizing the risk of leaks under pressure.

The flute geometry and cutting edges of the Dolphin HSS M-2 Hand Tap are optimized for efficient chip evacuation during the threading process. This helps prevent chip buildup and ensures smooth and consistent thread cutting without compromising thread integrity.

The comprehensive range of available sizes, from 1/16 inch to 4 inches, covers a wide range of pipe diameters commonly encountered in hydraulic and pneumatic systems. Each tap size is engineered with precision to deliver reliable performance and consistent thread profiles, maintaining compatibility with NPTF thread specifications.

To achieve optimal results and prolong tool life, it is recommended to use cutting fluids or lubricants during tapping operations. Proper lubrication helps reduce friction, dissipate heat, and improve chip evacuation, enhancing overall threading efficiency and extending the lifespan of the tap.

In summary, the Dolphin HSS M-2 Hand Tap in NPTF sizes from 1/16 inch to 4 inches is a durable and reliable tool for creating tapered internal threads in pipes and fittings used in hydraulic and pneumatic systems. Its high-speed steel construction, combined with efficient chip evacuation and compatibility with NPTF standards, makes it an essential component for thread tapping tasks in various industrial applications.
