Dolphin HSS M-2 Hand Tap, Size 1 to 2 Inch, UNEF/ NS

The Dolphin HSS M-2 Hand Tap, available in sizes ranging from 1 inch to 2 inches, is designed for tapping internal threads according to the Unified National Extra Fine (UNEF) and National Special (NS) standards. This hand tap is crafted from high-speed steel (HSS) grade M-2, which offers exceptional hardness, wear resistance, and heat tolerance, making it ideal for precision threading operations in a variety of materials.

The Dolphin HSS M-2 Hand Tap features a specialized design optimized for creating fine threads with the UNEF and NS specifications. These thread standards are commonly used in industries requiring high precision and thread strength, such as aerospace, automotive, and instrumentation.

The flute geometry and cutting edges of the Dolphin HSS M-2 Hand Tap are engineered to ensure efficient chip evacuation during the threading process. This helps maintain smooth and consistent cutting of threads while minimizing the risk of chip buildup, which can affect thread quality and tap performance.

The range of available sizes, from 1 inch to 2 inches, covers a spectrum of thread diameters commonly encountered in precision machining and manufacturing applications. Each tap size is crafted with precision to deliver reliable performance and consistent thread profiles that adhere to UNEF and NS thread specifications.

To achieve optimal results and extend 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.

In summary, the Dolphin HSS M-2 Hand Tap in UNEF/NS sizes from 1 inch to 2 inches offers durability, precision, and efficiency for creating fine internal threads in materials used in high-precision applications. Whether used in aerospace, automotive, or other industries requiring precise threading solutions, these hand taps provide reliable performance and thread quality for machinists and engineers seeking top-quality tools.
