Dolphin HSS Uncoated Metric Fine Hand Tap, Dia: 64-80 mm (Set of 2)

The Dolphin HSS Uncoated Metric Fine Hand Tap set, with a diameter range of 64-80 mm, is a specialized tool designed for creating metric fine threads in larger diameter holes and workpieces. These hand taps are manufactured from high-speed steel (HSS), renowned for its durability, toughness, and ability to maintain sharp cutting edges in challenging threading applications.

Key features of the Dolphin HSS Uncoated Metric Fine Hand Tap set (64-80 mm diameter) include:

1. Metric Fine Thread Pitch: The hand taps are engineered to cut metric fine threads, which have a tighter pitch compared to standard metric threads. This makes them suitable for applications requiring strong and precise thread engagement, especially in larger diameter holes.

2. Diameter Range: The set includes hand taps with diameters ranging from 64 mm to 80 mm, providing versatility to accommodate different threading requirements within this specific size range.

3. Uncoated Surface: The hand taps feature an uncoated surface, which facilitates efficient chip evacuation during threading operations. This helps prevent tool clogging and ensures smooth cutting performance even in larger diameter holes and thicker materials.

4. High-Speed Steel (HSS) Construction: The use of HSS material ensures that the hand taps maintain their hardness and toughness, allowing them to withstand the high stresses and temperatures encountered during threading tasks in larger workpieces.

5. Precision Cutting: Each hand tap in the set is precision ground to produce clean and accurate metric fine threads, ensuring reliable thread fit and functionality, particularly in larger diameter applications.

6. Versatility: The Dolphin HSS Metric Fine Hand Tap set is suitable for use in heavy-duty industries such as manufacturing, metalworking, shipbuilding, and construction, where metric fine threads are required for specific applications in large-scale components and structures.

7. Ease of Use: The hand taps feature a tapered end and a square drive interface compatible with standard tap wrenches, allowing for easy and controlled manual threading operations even in larger diameter holes and workpieces.

Proper lubrication and careful handling are crucial when using the Dolphin HSS Uncoated Metric Fine Hand Tap set (64-80 mm diameter) to optimize tool performance and lifespan. With their robust construction and precision cutting capabilities, these hand taps are indispensable tools for achieving high-quality metric fine threads in large-scale machining and fabrication projects.
