Dolphin HSS Straight Flute Short Hand Tap, BSW, Size: 1/16 to 7/8 Inch (Set of 3)

The Dolphin HSS Straight Flute Short Hand Tap set for British Standard Whitworth (BSW) threads, ranging from 1/16 inch to 7/8 inch in size, consists of three high-speed steel (HSS) hand taps designed for tapping coarse 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), known for its hardness, toughness, and wear resistance. HSS taps are suitable for tapping threads in metals, including steel, aluminum, brass, and other alloys.

2. Straight Flute Design: These hand taps feature a straight flute design, characterized by straight grooves along the tap body. The straight flute design helps in efficient chip evacuation during the tapping process.

3. British Standard Whitworth (BSW) Thread Pitch: This tap set is designed for tapping British Standard Whitworth (BSW) threads, which are coarse threads commonly used in various applications, including automotive, construction, and general engineering.

4. Range of Sizes: The tap sizes in the set cover a range from 1/16 inch to 7/8 inch, allowing for the creation of BSW threads in various diameters commonly encountered in industrial applications.

5. Set of Three Taps: The set includes three hand taps per size—typically a taper (starter) tap, a plug (intermediate) tap, and a bottoming (finishing) tap. The taper tap has a more pronounced chamfer to assist in starting the thread, the plug tap is used for continuing the threading process, and the bottoming tap is used for finishing threads close to the bottom of blind holes.

6. Versatile Applications: Dolphin HSS Straight Flute Short Hand Taps for BSW threads are suitable for various industrial applications requiring coarse threads with good strength and durability. They are commonly used in construction, machinery, and repair applications.

7. 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 important to use cutting fluid or lubricant during tapping to improve tool life and thread quality, especially when working with harder materials.
