Hertel K008007AS25 Spiral Point Tap 0-80 Unf Hss Tin

Product Description

The HERTEL K008007AS25 is a spiral point tap designed for cutting 0-80 UNF internal threads in a single pass. Spiral point taps push chips forward ahead of the cutting edge, making them well-suited for through-hole tapping operations where chip evacuation is critical. This tap is manufactured from high-speed steel (HSS) with a titanium nitride (TiN) coating that extends tool life by reducing friction and increasing surface hardness. It features a plug chamfer, 2 flutes, a right-hand thread direction, and a 2B class of fit. The H2 thread limit provides controlled tolerance for standard 2B fit applications in ferrous and non-ferrous materials.

This tap is used in machine shop, toolroom, and production environments where precision 0-80 UNF threaded holes are required. The 0-80 designation is among the finest machine screw threads in common use, appearing in instrument, optical, and electronics assembly work as well as precision mechanical components. The plug chamfer makes it appropriate for through-hole applications or blind holes with adequate thread runout. It is compatible with tapping heads, CNC machining centers, drill presses, and manual tapping operations using appropriate tap wrenches.

Key Features

• Spiral point geometry pushes chips forward for efficient through-hole tapping
• TiN coating increases surface hardness and reduces friction for extended tool life
• High-speed steel construction handles a wide range of workpiece materials
• H2 thread limit maintains tight tolerance control for 2B class of fit
• Plug chamfer provides gradual thread engagement suited to through-hole and most blind-hole applications
• Right-hand thread direction for standard tapping operations

Compatibility

Designed for cutting 0-80 UNF 2B class internal threads in through-hole applications across ferrous and non-ferrous materials. Suitable for use with standard tapping heads, CNC machining centers, and manual tapping equipment accepting the appropriate shank diameter.

Installation Notes

Use appropriate cutting fluid or tapping compound for the workpiece material to maximize tool life and thread quality. Ensure the tap is aligned perpendicular to the workpiece surface before engaging to prevent tap breakage, which is a significant risk at 0-80 sizing. When using power tapping equipment, verify that torque settings are appropriate for this thread size to avoid overload. Handle with care, as small-diameter taps are brittle and susceptible to breakage under lateral loading.
