Dolphin M2 6H HSS Straight Hand Tap (Size: M16x1.5 to 30x3.5) (Set of 3)

The Dolphin M2 6H HSS Straight Hand Tap (Size: M16x1.5 to M30x3.5) (Set of 3) is a specialized set of hand taps designed for cutting internal metric threads in larger sizes, from M16x1.5 to M30x3.5 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), which is renowned for its toughness, wear resistance, and ability to maintain cutting edge sharpness at high temperatures. This material is suitable for threading operations in various metals including steel, stainless steel, aluminum, and alloys.

2. Thread Standard and Sizes: The taps conform to the metric thread specifications and cover a range of larger sizes from M16x1.5 to M30x3.5. These sizes are commonly used in industrial applications requiring larger metric threads.

3. 6H Tolerance Class: The "6H" designation indicates the thread tolerance class, ensuring that the taps produce threads with a close tolerance fit suitable for precision applications. This results in 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 contribute to smooth and efficient cutting of threads, particularly in larger sizes.

5. Set of Three Taps: The set includes three hand taps—typically a taper tap (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 to the desired depth.

6. Application: The Dolphin M2 6H HSS Straight Hand Tap Set (Size: M16x1.5 to M30x3.5) (Set of 3) is ideal for threading larger metric sizes commonly found in heavy machinery, automotive components, construction equipment, and other industrial applications.

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, especially in larger sizes and tougher materials.

8. Versatility: This hand tap set covers a comprehensive range of larger metric thread sizes and pitches, providing versatility for threading operations in various industrial settings.

In summary, the Dolphin M2 6H HSS Straight Hand Tap (Size: M16x1.5 to M30x3.5) (Set of 3) is a high-quality tool set designed for creating precise metric threads in larger sizes. 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 industrial applications.
