Dolphin HSS Straight Flute Short Hand Tap, Size 1-1/2 Inch, UNC

The Dolphin HSS Straight Flute Short Hand Tap, available in sizes ranging from 1 inch to 4 inches for Unified National Coarse (UNC) threads, is a robust cutting tool designed for creating internal threads in a variety of materials. This hand tap is crafted from high-speed steel (HSS), renowned for its hardness, wear resistance, and heat tolerance, making it suitable for demanding threading operations in metals such as steel, stainless steel, aluminum, brass, and other alloys.

The straight flute design of the Dolphin HSS Short Hand Tap allows for efficient chip evacuation during the threading process. This design feature helps prevent chip buildup in the flutes, ensuring smooth and uninterrupted cutting of threads while reducing the risk of tool breakage or damage. Effective chip removal is crucial for maintaining thread accuracy and extending the tap's lifespan.

These short hand taps are ideal for manual threading operations where precision and control are essential. The compact size and straight flute configuration make them easy to handle and maneuver, particularly in tight or confined spaces where larger machinery may not be practical. They can be used for creating both through-holes and blind holes, depending on the threading requirements of the application.

The comprehensive range of available sizes, from 1 inch to 4 inches, covers a wide range of thread diameters commonly used in industrial settings. Each tap size is engineered with precision to deliver reliable performance and consistent thread profiles compatible with UNC thread specifications.

To optimize performance and tool life, it is recommended to use cutting fluids or lubricants during tapping operations. Proper lubrication helps reduce friction, dissipate heat, and improve chip evacuation, enhancing overall threading efficiency and extending the lifespan of the tap.

In summary, the Dolphin HSS Straight Flute Short Hand Tap in UNC sizes from 1 inch to 4 inches offers durability, precision, and ease of use for creating accurate internal threads in a variety of materials. Whether used in manufacturing, construction, automotive, or general metalworking applications, these hand taps provide reliable threading solutions for machinists and fabricators seeking high-quality tools.
