Dolphin HSS Uncoated Metric Fine Hand Tap, Dia: 110-140 mm (Set of 2)

The Dolphin HSS Uncoated Metric Fine Hand Tap set, with a diameter range of 110-140 mm, represents a specialized tool designed for cutting metric fine threads in large diameter holes or workpieces. These hand taps are constructed from high-speed steel (HSS), which is chosen for its durability and ability to maintain sharp cutting edges under demanding threading conditions.

Key features and considerations for the Dolphin HSS Uncoated Metric Fine Hand Tap set (110-140 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 workpieces.

2. Diameter Range: The set includes hand taps with diameters ranging from 110 mm to 140 mm, providing versatility to accommodate different threading requirements within this specific size range.

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

4. High-Speed Steel (HSS) Construction: The use of HSS material ensures that the hand taps can withstand the high stresses and temperatures encountered during threading tasks in large workpieces, providing extended tool life and durability.

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 Uncoated Metric Fine Hand Tap set is suitable for use in heavy-duty industries such as manufacturing, construction, shipbuilding, and engineering, where metric fine threads are required for specific applications in large-scale components and structures.

7. 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 and workpieces.
