Dolphin HSS M-2 Hand Tap, Size: 1/8 to 4 Inch, NPS

The Dolphin HSS M-2 Hand Tap, available in sizes ranging from 1/8 inch to 4 inches, is specifically designed for tapping internal threads according to the National Pipe Straight (NPS) standard. This type of hand tap is essential for creating precise threads in pipes and fittings used in plumbing, construction, and various industrial applications.

The Dolphin HSS M-2 Hand Tap is constructed from high-speed steel (HSS) grade M-2, renowned for its hardness, wear resistance, and ability to withstand high temperatures generated during threading operations. This ensures durability and longevity, making the tap suitable for continuous use in demanding environments.

The hand tap features a design optimized for efficient thread cutting. The flute geometry and cutting edges are carefully engineered to facilitate smooth chip evacuation during the tapping process. This helps prevent chip buildup and ensures consistent, accurate threading without compromising on thread quality.

The range of available sizes, from 1/8 inch to 4 inches, covers a wide spectrum of pipe diameters commonly encountered in industrial settings. Each tap size is crafted with precision to deliver reliable performance and consistent thread profiles, maintaining compatibility with NPS thread specifications.

The Dolphin HSS M-2 Hand Tap is suitable for use with various pipe materials, including steel, stainless steel, brass, and other alloys. Proper lubrication with cutting fluids or oils is recommended during tapping to optimize performance, reduce friction, and extend the tool's lifespan.

Overall, the Dolphin HSS M-2 Hand Tap in NPS sizes from 1/8 inch to 4 inches offers machinists and pipefitters a reliable and durable tool for creating accurate internal threads in pipes and fittings. Its high-speed steel construction, combined with efficient chip evacuation and compatibility with NPS standards, makes it an essential component in pipe threading operations across different industries.
