Dolphin M2 6H HSS Straight Hand Tap (Size: M3x0.5 to 14x2) (Set of 3)

The Dolphin M2 6H HSS Straight Hand Tap (Size: M3x0.5 to M14x2) (Set of 3) is a specialized set of hand taps designed for cutting internal threads in a range of metric sizes, from M3x0.5 to M14x2 thread pitches. Here's a detailed overview of this specific hand tap set:

1. Material and Construction: The hand taps are made from M2 high-speed steel (HSS), known for its toughness, wear resistance, and ability to maintain cutting edge sharpness even at high temperatures. This material is suitable for threading operations in various materials including steel, stainless steel, aluminum, and alloys.

2. Thread Standard and Sizes: The taps conform to the standard metric thread specifications and cover a range of sizes from M3x0.5 to M14x2. This range includes different thread pitches suitable for various applications requiring metric threads.

3. 6H Tolerance Class: The "6H" designation refers to the thread tolerance class, indicating that the taps produce threads with a close tolerance fit suitable for precision applications. This ensures high-quality threads with consistent dimensions.

4. Straight Flute Design: The taps feature straight flutes, which aid in chip evacuation during the threading process and help ensure smooth and efficient cutting of threads.

5. Set of Three Taps: The set includes three hand taps—typically a taper tap (also known as a "first" tap), a second tap (intermediate tap), and a plug tap (finishing tap). Each tap serves a specific purpose in threading operations, with the taper tap starting the thread, the second tap continuing it, and the plug tap finishing it.

6. Application: The Dolphin M2 6H HSS Straight Hand Tap Set (Size: M3x0.5 to M14x2) (Set of 3) is ideal for threading a range of metric sizes in various materials used in industries such as manufacturing, automotive, aerospace, and general engineering.

7. Usage Recommendations: When using these hand taps, it's recommended to use cutting oil or lubricant to reduce friction, dissipate heat, and prolong tool life. Proper lubrication also aids in chip evacuation and improves overall threading performance.

8. Versatility: This hand tap set covers a comprehensive range of metric thread sizes and pitches, providing versatility for threading operations across different industries and applications.

In summary, the Dolphin M2 6H HSS Straight Hand Tap (Size: M3x0.5 to M14x2) (Set of 3) is a high-quality tool set designed for creating precise metric threads in various materials. Its M2 HSS construction, combined with the 6H tolerance class and three-tap set, ensures reliable performance, durability, and precision in threading operations for a wide range of applications.
