Dolphin M35 6H HSS Straight Hand Tap (Size: M16x15 to 24x3) (Set of 2)

The Dolphin M35 6H HSS Straight Hand Tap (Size: M16x1.5 to M24x3) (Set of 2) is a specialized set of hand taps designed for cutting internal metric threads in larger sizes, specifically ranging from M16x1.5 to M24x3 thread pitches. Here's a detailed overview of this specific hand tap set:

1. Material and Construction: The hand taps in this set are made from M35 high-speed steel (HSS) with added cobalt content. M35 HSS offers superior hardness, wear resistance, and heat resistance compared to standard M2 HSS, making it suitable for threading tough materials such as stainless steel, alloy steels, and hardened metals.

2. Thread Standard and Sizes: The taps conform to the standard metric thread specifications and cover a range of larger sizes from M16x1.5 to M24x3. These sizes are commonly used in heavy machinery, automotive components, construction equipment, and other 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.

5. Set of Two Taps: The set includes two hand taps—typically a taper tap (first tap) and a plug tap (finishing tap). Each tap serves a specific purpose in threading operations, with the taper tap starting the thread and the plug tap finishing it to the desired depth.

6. Application: The Dolphin M35 6H HSS Straight Hand Tap Set (Size: M16x1.5 to M24x3) (Set of 2) is ideal for threading larger metric sizes commonly found in heavy machinery, automotive components, and other industrial equipment.

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 specific range of larger metric thread sizes and pitches, providing versatility for threading operations in different industries and applications.

In summary, the Dolphin M35 6H HSS Straight Hand Tap (Size: M16x1.5 to M24x3) (Set of 2) is a high-quality tool set designed for creating precise metric threads in larger sizes. Its M35 HSS construction, combined with the 6H tolerance class and two-tap set, ensures reliable performance, durability, and precision in threading operations for heavy-duty industrial applications.
