Dolphin HSS Uncoated Metric Fine Hand Tap, Dia: 3-10 mm (Set of 2)

The Dolphin HSS Uncoated Metric Fine Hand Tap set, ranging from 3 mm to 10 mm in diameter, consists of two high-speed steel (HSS) hand taps specifically designed for tapping fine metric threads in various materials. Here are the key features and details of this tap set:

1. High-Speed Steel (HSS) Construction: The hand taps are made from high-speed steel (HSS), which provides excellent hardness, toughness, and wear resistance. HSS taps are suitable for tapping threads in ferrous and non-ferrous metals, as well as other materials like plastics and composites.

2. Metric Fine Thread Pitch: This tap set is designed for tapping fine metric threads, denoted as Metric Fine (MF). The tap sizes in the set cover a range from 3 mm to 10 mm in diameter, allowing for the creation of various fine threads commonly used in precision engineering applications.

3. Uncoated Finish: The taps feature an uncoated finish, which is typical for general-purpose tapping applications. While uncoated taps may require more frequent lubrication and are not as resistant to wear as coated taps, they provide good performance in many materials and can be easily resharpened.

4. Set of Two Taps: The set includes two hand taps per diameter—typically a taper (starter) tap and a plug (intermediate) tap. The taper tap has a more pronounced chamfer to assist in starting the thread, while the plug tap is used for continuing and finishing the threading process.

5. Versatile Applications: Dolphin HSS Uncoated Metric Fine Hand Taps are suitable for a wide range of applications, including automotive, aerospace, manufacturing, and general machining. They are commonly used to create precise threads in materials requiring fine thread pitches.

6. Hand Tapping Operations: These taps are designed for manual hand tapping operations, where the taps are turned by hand with a tap wrench. It is essential to use cutting fluid or lubricant during tapping to improve tool life and thread quality.

7. Precision Machining: The fine metric threads created by these taps are ideal for applications requiring high precision, such as instrumentation, toolmaking, and model engineering.

In summary, the Dolphin HSS Uncoated Metric Fine Hand Tap set offers a range of high-quality HSS taps for creating fine metric threads in various materials. The uncoated finish provides versatility, while the durable HSS construction ensures reliable performance in precision machining tasks. This tap set is a valuable addition to any workshop or machining facility requiring precise thread tapping capabilities in metric fine thread sizes.
