Dolphin HSS Uncoated Helicoil Tap, Dia: 20 to 48 mm

The Dolphin HSS Uncoated Helicoil Tap, with diameters ranging from 20 to 48 mm, is a specialized cutting tool designed for preparing large 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 and durable threads suitable for helicoil installation in larger diameter holes. Helicoil inserts are used to reinforce or repair damaged threads, providing a strong and reliable threaded connection in industrial and maintenance applications.

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 20 to 48 mm, covers a variety of large hole sizes commonly encountered in heavy-duty 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 use with manual or machine tapping operations, providing versatility for threading tasks requiring larger diameter helicoil inserts. 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 20 to 48 mm offers durability and precision for preparing large holes to accept helicoil wire inserts in a variety of materials. Whether used in heavy machinery, construction, or maintenance applications, this helicoil tap provides a reliable solution for thread preparation and repair tasks, contributing to strong and secure threaded connections.
