Dolphin HSS Uncoated Metric Fine Hand Tap, Dia: 64-80 mm

The Dolphin HSS Uncoated Metric Fine Hand Tap set, with diameters ranging from 64 mm to 80 mm, is a specialized tool designed for creating metric fine threads in large diameter holes and workpieces. These hand taps are crafted from high-speed steel (HSS), known for its durability and ability to maintain sharp cutting edges in demanding 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 specifically designed to cut metric fine threads with a tighter pitch, ensuring strong and precise thread engagement suitable for larger diameter holes.

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

3. High-Speed Steel (HSS) Construction: The use of HSS material ensures durability and longevity, making the hand taps capable of withstanding the high stresses and temperatures encountered during threading tasks in large workpieces.

4. 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 in large diameter workpieces.

5. Versatility: The Dolphin HSS Uncoated Metric Fine Hand Tap set is suitable for use in various industries, including heavy machinery, construction, shipbuilding, and manufacturing, where metric fine threads are required for specific applications in large components.

6. Ease of Use: The hand taps are designed with 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.

7. Applications: This hand tap set is ideal for threading holes in materials such as steel, stainless steel, cast iron, and other metals commonly used in heavy-duty applications.

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