Dolphin M2 6H HSS Straight Hand Tap (Size: M16x1.5 to 30x3.5) (Set of 2)

The Dolphin M2 6H HSS Straight Hand Tap (Size: M16x1.5 to 30x3.5) (Set of 2) is a specialized set of hand taps designed for cutting internal threads in a range of larger metric sizes, from M16x1.5 to M30x3.5 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), which is known for its toughness, wear resistance, and ability to maintain sharp cutting edges 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 Class: The taps conform to the standard metric thread specifications, covering a range of larger sizes from M16 to M30 with different thread pitches (1.5mm to 3.5mm). 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 (starting tap) and a plug tap (finishing tap). The taper tap is used to start the thread, while the plug tap continues and finishes it.

5. Application: The Dolphin M2 6H HSS Straight Hand Tap Set (Size: M16x1.5 to 30x3.5) (Set of 2) is ideal for threading larger metric sizes in various industrial applications such as machine shops, manufacturing facilities, automotive repair, and maintenance workshops.

6. Usage Recommendations: It's recommended to use cutting oil or lubricant when using these hand taps to reduce friction, dissipate heat, and prolong tool life. Proper lubrication also helps in chip evacuation and improves threading performance.

7. Versatility: This hand tap set covers a range of larger 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: M16x1.5 to 30x3.5) (Set of 2) 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, ensures reliable performance and durability in precision threading operations for larger diameter holes.
