Dolphin M35 6H HSS SPPT Hand Tap

The Dolphin M35 6H HSS SPPT Hand Tap is a specialized hand tool designed for creating precision threads in various materials, particularly those that are tougher and more resistant to traditional cutting methods. Here's an overview of the key features and characteristics of this hand tap:

1. Material and Construction: The hand tap is crafted from M35 high-speed steel (HSS), which contains added cobalt for enhanced hardness, heat resistance, and wear resistance compared to standard M2 HSS. This makes the tap suitable for threading operations in challenging materials like stainless steel, alloy steels, and other hardened metals.

2. Thread Standard and Class: The tap conforms to the SPPT (Special Purpose Precision Thread) standard, indicating a specialized thread form designed for specific applications. The "6H" designation refers to the thread tolerance class, indicating that the tap produces threads with a close tolerance fit suitable for precision engineering and manufacturing.

3. Hand Tap Design: This hand tap is specifically designed for manual threading operations where precise and accurate threads need to be created. It features straight flutes that aid in chip evacuation and ensure smooth cutting during threading.

4. Application: The Dolphin M35 6H HSS SPPT Hand Tap is ideal for use in industries such as aerospace, automotive, and precision engineering, where high-quality and durable threads are essential for assembly and component manufacturing.

5. Usage Recommendations: When using this hand tap, it's important to use cutting oil or lubricant to reduce friction and heat generation, which helps prolong tool life and ensures clean and accurate threads. Proper lubrication also helps prevent chip buildup and improves overall threading performance.

6. Versatility: Despite its specialized design, the Dolphin M35 6H HSS SPPT Hand Tap is versatile and can be used in various applications requiring precise threading in tough materials.

In summary, the Dolphin M35 6H HSS SPPT Hand Tap is a premium-quality tool suited for creating precision threads in challenging materials. Its M35 HSS construction with cobalt additives, combined with the SPPT thread standard and 6H tolerance class, ensures superior performance, durability, and reliability in precision threading applications across different industries.
