Dolphin HSS M-2 Tin Coated SPPT Taps, UNC, 6H

The Dolphin HSS M-2 Tin Coated SPPT Taps with UNC (Unified National Coarse) threading and 6H tolerance are precision tools designed for tapping threads in various materials, offering durability and efficiency in machining operations.

Key features and details of the Dolphin HSS M-2 Tin Coated SPPT Taps (UNC, 6H) include:

1. High-Speed Steel (HSS) M-2 Construction: The taps are made from high-speed steel (HSS) M-2, a robust material known for its hardness, wear resistance, and toughness. HSS M-2 taps are capable of withstanding the rigors of tapping operations.

2. Tin Coating: The taps feature a Titanium Nitride (TiN) coating, which enhances their surface hardness, reduces friction, and improves chip evacuation during tapping. The TiN coating extends tool life and enhances performance, particularly in challenging materials.

3. SPPT (Spiral Point Plug Taps) Design: The taps have a spiral point design, also known as gun taps, which are used for through-hole tapping applications. The spiral point helps push chips forward and out of the hole during tapping, improving efficiency and reducing the risk of chip buildup.

4. UNC (Unified National Coarse) Thread: The taps are designed for creating threads according to the Unified National Coarse (UNC) thread specification. UNC threads have a coarse pitch and are commonly used in general-purpose applications for fastening and assembly.

5. 6H Tolerance: The taps have a 6H tolerance class, indicating a standard tolerance level for thread tapping tools. This tolerance ensures consistent and accurate thread dimensions, meeting industry standards and specifications.

6. Application: Dolphin HSS M-2 Tin Coated SPPT Taps (UNC, 6H) are suitable for tapping UNC threads in materials such as steel, aluminum, brass, and other alloys. They are ideal for use in manual or CNC tapping operations in various industrial and manufacturing settings.

In summary, Dolphin HSS M-2 Tin Coated SPPT Taps with UNC threading and 6H tolerance are reliable cutting tools designed for producing high-quality UNC threads in metals. The combination of high-speed steel construction, TiN coating, spiral point design, and precise tolerance class ensures efficient and accurate tapping operations, contributing to enhanced productivity and thread quality. These taps are essential tools for creating strong and durable threads for fastening and assembly applications.
