Dolphin M35 6H HSS Straight Hand Tap (Size: M16x15 to 24x3) (Set of 3)

The Dolphin M35 6H HSS Straight Hand Tap (Size: M16x1.5 to M24x3) (Set of 3) is a specialized set of hand taps designed for cutting internal threads in a range of metric sizes, specifically from M16x1.5 to M24x3 thread pitches. Here are the key details about this specific hand tap set:

1. Material and Construction: The hand taps are made from M35 high-speed steel (HSS), which contains added cobalt for enhanced hardness, heat resistance, and wear resistance compared to standard M2 HSS. This material is well-suited for threading operations in tough materials such as stainless steel, alloy steels, and other hardened metals.

2. Thread Standard and Class: The taps conform to the standard metric thread specifications, covering a range of sizes from M16 to M24 with different thread pitches (1.5mm to 3mm). 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 Three Taps: The set includes three hand taps—typically a taper tap (starting tap), a second tap (intermediate tap), and a bottoming tap (finishing tap). Each tap serves a specific purpose in threading operations, with the taper tap initiating the thread, the second tap continuing it, and the bottoming tap finishing the thread near the bottom of a blind hole.

5. Application: The Dolphin M35 6H HSS Straight Hand Tap Set (Size: M16x1.5 to M24x3) (Set of 3) is ideal for threading a range of metric sizes in tough materials, commonly used in industries such as manufacturing, automotive, aerospace, and general engineering.

6. Usage Recommendations: It's recommended to use cutting oil or lubricant during threading operations to reduce friction, dissipate heat, and prolong the tool life. Proper lubrication also helps in chip evacuation and improves threading performance, especially in tougher materials.

7. Versatility: This hand tap set covers a range of metric thread sizes and pitches, providing versatility for threading operations across different industries and applications where precise and durable threads are required.

In summary, the Dolphin M35 6H HSS Straight Hand Tap (Size: M16x1.5 to M24x3) (Set of 3) is a high-quality tool set designed for creating precise metric threads in tough materials. Its M35 HSS construction, combined with the 6H tolerance class, ensures reliable performance, durability, and precision in threading operations across various industrial applications.
