Dolphin HSS Uncoated Helicoil Tap, Size: 3/16 to 1 Inch, UNC

The Dolphin HSS Uncoated Helicoil Tap, available in sizes ranging from 3/16 to 1 Inch, is specifically designed for creating internal threads compatible with the Unified National Coarse (UNC) standard. This type of helicoil tap is essential for preparing holes to accept helical wire inserts (helicoils) used to reinforce and repair threaded connections in a wide range of materials.

Crafted from high-speed steel (HSS), the Dolphin HSS Uncoated Helicoil Tap offers excellent hardness and durability, making it suitable for tapping holes in materials such as steel, stainless steel, aluminum, and other alloys commonly encountered in manufacturing and maintenance applications.

The helicoil tap features a straight flute design optimized for effective chip evacuation during the tapping process. This design helps prevent chip buildup in the flutes, ensuring smooth and uninterrupted cutting of threads necessary for accommodating helicoil inserts.

The range of available sizes, from 3/16 to 1 Inch Inch, covers a variety of hole diameters commonly used for helicoil installations. Each tap size is engineered with precision to deliver reliable performance and consistent thread profiles compatible with UNC thread specifications.

The Dolphin HSS Uncoated Helicoil Tap is suitable for use in manual or machine tapping operations, providing versatility for different threading applications. Proper lubrication with cutting fluids or oils is recommended during tapping to optimize performance, reduce friction, and extend the tool's lifespan.

Helicoil taps play a crucial role in the repair and reinforcement of damaged or worn threads, allowing for efficient restoration of threaded connections without the need for more extensive repairs or replacements.

In summary, the Dolphin HSS Uncoated Helicoil Tap in UNC sizes from 3/16 to 1 Inch Inch is a durable and reliable tool for preparing holes to accept helicoil wire inserts in a variety of materials. Its high-speed steel construction, combined with efficient chip evacuation and compatibility with UNC standards, makes it an essential component for helicoil installation and thread repair tasks in manufacturing, automotive, and maintenance industries.
