Dolphin M1.2 to M1.4 mm HSS Straight Flute Short Hand Tap

The Dolphin HSS Straight Flute Short Hand Tap for sizes M1.2 to M1.4 mm is a precision cutting tool designed for tapping small metric threads. Here's an overview of this specific hand tap:

1. Material and Construction: The hand tap is typically made from high-speed steel (HSS), a durable and tough material suitable for cutting threads in metal. HSS provides good wear resistance and maintains sharp cutting edges, making it ideal for tapping operations.

2. Thread Sizes: The tap is designed to cut metric threads with sizes ranging from M1.2 to M1.4 mm. These are very small thread sizes commonly used in precision engineering and electronics applications.

3. Straight Flute Design: The tap features straight flutes, which aid in chip evacuation during the threading process. The straight flute design helps ensure efficient cutting and smooth thread production, especially in small-diameter holes.

4. Hand Tap: This is a manual threading tool meant to be operated by hand using a tap wrench. It is used for creating internal threads in pre-drilled holes or existing openings.

5. Short Flute Length: The "short flute" designation indicates that the tap has a shorter flute length compared to standard taps. This feature is beneficial for threading in confined spaces or shallow holes.

6. Application: The Dolphin HSS Straight Flute Short Hand Tap (M1.2 to M1.4 mm) is commonly used in precision machining, electronics manufacturing, model making, and other applications requiring small, accurate threads.

7. Usage Recommendations: When using this hand tap, it's important to use cutting oil or lubricant to reduce friction and heat buildup. Lubrication helps prolong the tool life and ensures smoother thread cutting.

8. Precision Tooling: Due to the small thread sizes, this tap requires careful handling and precision during operation to avoid breakage and ensure accurate thread formation.

In summary, the Dolphin HSS Straight Flute Short Hand Tap for sizes M1.2 to M1.4 mm is a specialized tool designed for tapping small metric threads with precision and efficiency. Its high-speed steel construction and straight flute design make it suitable for creating accurate internal threads in various materials, making it an essential tool for applications requiring fine-threaded components.
