Dolphin HSS Uncoated Helicoil Tap, Dia: 2 to 18 mm

The Dolphin HSS Uncoated Helicoil Tap, with diameters ranging from 2 to 18 mm, is a specialized cutting tool designed for preparing holes to accept helical wire inserts (helicoils) in various materials. This helicoil tap is crafted from high-speed steel (HSS), which offers excellent hardness and durability for threading operations in metals such as steel, stainless steel, aluminum, and other alloys.

The primary purpose of the Dolphin HSS Uncoated Helicoil Tap is to create precise threads in preparation for helicoil installation. Helicoil inserts are used to reinforce or repair damaged threads, providing a strong and reliable threaded connection.

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

The range of diameters, from 2 to 18 mm, covers a variety of hole sizes commonly encountered in helicoil applications across different industries. Each tap size is engineered with precision to deliver reliable performance and consistent thread profiles compatible with helicoil insert specifications.

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

In summary, the Dolphin HSS Uncoated Helicoil Tap in diameters ranging from 2 to 18 mm offers durability and precision for preparing holes to accept helicoil wire inserts in various materials. Whether used in automotive, aerospace, or general manufacturing applications, this helicoil tap provides a reliable solution for thread preparation and repair tasks, contributing to strong and secure threaded connections.
