Dolphin HSS Uncoated Metric Fine Hand Tap, Dia: 85-100 mm

The Dolphin HSS Uncoated Metric Fine Hand Tap set, with diameters ranging from 85 mm to 100 mm, represents a specialized tool designed for creating metric fine threads in very large diameter holes and workpieces. These hand taps are constructed from high-speed steel (HSS), chosen for its durability and capability to maintain sharp cutting edges in demanding threading applications.

Key Features:

1. Metric Fine Thread Pitch: These hand taps are engineered specifically to cut metric fine threads, which have a tighter pitch compared to standard metric threads. This feature ensures strong and precise thread engagement suitable for very large diameter holes.

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

3. High-Speed Steel (HSS) Construction: The use of HSS material ensures durability and longevity, allowing the hand taps to withstand 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 very large diameter workpieces.

5. Versatility: The Dolphin HSS Uncoated Metric Fine Hand Tap set is suitable for use in heavy-duty industries such as manufacturing, construction, shipbuilding, and infrastructure, where metric fine threads are required for specific applications in very 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, facilitating easy and controlled manual threading operations even in very large 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 industrial applications requiring metric fine threads.

Proper lubrication and careful handling are crucial when using the Dolphin HSS Uncoated Metric Fine Hand Tap set (85-100 mm diameter) to optimize tool performance and extend tool life. With their robust construction and precision cutting capabilities, these hand taps are essential tools for achieving high-quality metric fine threads in very large diameter applications.
