Dolphin M2 6H HSS Straight Hand Tap (Size: M3x0.5 to 14x2) (Set of 2)

The Dolphin M2 6H HSS Straight Hand Tap (Size: M3x0.5 to 14x2) (Set of 2) is a set of precision hand taps designed for cutting internal threads in a range of metric sizes, from M3x0.5 to 14x2 thread pitches. Here are the key details about 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 cutting threads in a wide range of materials including steel, stainless steel, aluminum, and various alloys.

2. Thread Standard and Class: The taps conform to the standard metric thread specifications, covering a range of sizes from M3 to M14 with different thread pitches (0.5mm to 2mm). The "6H" designation refers to the thread tolerance class, indicating that the taps produce threads with a close tolerance fit suitable for precision applications.

3. 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.

4. Set of Two Taps: The set includes two hand taps—typically a taper tap (also known as a "first" tap) and a plug tap (also known as a "second" tap). These taps are used sequentially for threading operations, with the taper tap starting the thread and the plug tap continuing and finishing it.

5. Application: The Dolphin M2 6H HSS Straight Hand Tap Set is suitable for various industrial applications where precision threading is required, such as machine shops, manufacturing facilities, automotive repair, and maintenance workshops.

6. Usage Recommendations: When using these hand taps, it's recommended to use cutting oil or lubricant to reduce friction and heat generation, which helps prolong the tool life and ensures clean and accurate threads. Proper lubrication also aids in chip evacuation and improves overall threading performance.

7. Versatility: The hand tap set covers a wide range of metric thread sizes and pitches, making it versatile for use in different threading applications across industries.

In summary, the Dolphin M2 6H HSS Straight Hand Tap (Size: M3x0.5 to 14x2) (Set of 2) 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, ensures reliable performance and durability in precision threading operations.
