Dolphin UNC Type M-2 HSS Taps (Set of 3)

The Dolphin UNC Type M-2 HSS Taps (Set of 3) are high-quality taps designed for cutting internal threads according to the Unified National Coarse (UNC) thread standard. Crafted from M-2 high-speed steel (HSS), these taps offer excellent hardness, wear resistance, and durability, making them suitable for threading operations in various materials including steel, stainless steel, aluminum, brass, and other alloys.

Key features and characteristics of the Dolphin UNC Type M-2 HSS Taps include:

1. Unified National Coarse (UNC) Threads: The taps are specifically designed to cut threads conforming to the UNC standard, which is widely used in general-purpose threading applications.

2. M-2 High-Speed Steel Construction: The use of M-2 HSS ensures superior hardness and wear resistance, allowing the taps to maintain sharp cutting edges and withstand the demands of threading operations.

3. Three-Tap Set: The set typically includes three taps: a taper tap (also known as a "first" tap), an intermediate tap, and a bottoming tap. This three-tap approach allows for progressive cutting of threads, starting with the taper tap and advancing to the bottoming tap to reach full thread depth.

4. Precision Thread Design: The taps feature precise thread profiles that conform to UNC standards, ensuring compatibility with UNC nuts, bolts, and fittings.

5. Efficient Chip Evacuation: The taps are designed with optimized flute geometry to facilitate chip removal during threading, minimizing the risk of chip buildup and ensuring smooth cutting of threads.

6. Versatility: The Dolphin UNC Type M-2 HSS Taps are suitable for use in manual or machine threading operations, providing versatility for various applications in manufacturing, construction, automotive, and other industries requiring UNC threads.

7. Usage Recommendations: It is recommended to use cutting fluids or lubricants during tapping to optimize performance, reduce friction, and extend the lifespan of the taps. Proper lubrication helps maintain thread quality and prevents overheating during threading operations.

In summary, the Dolphin UNC Type M-2 HSS Taps (Set of 3) are essential tools for professionals and enthusiasts working with UNC threads in various materials. Their M-2 HSS construction, precision design, and efficient chip evacuation make them reliable for achieving accurate and durable threads in a wide range of general-purpose threading applications.
