Hertel K008005AS Spiral Point Tap 0-80 Unf 2 Flutes Hss

Product Description

The HERTEL K008005AS is a spiral point tap designed for cutting 0-80 UNF internal threads in through-hole applications. This high speed steel tap uses a plug chamfer and a two-flute spiral point geometry to push chips forward ahead of the cutting zone, keeping flutes clear during the threading operation. The H1 thread limit holds tight tolerances appropriate for 3B class fits. The bright finish leaves the base HSS surface exposed, making it a dependable choice for general-purpose threading in ferrous and non-ferrous materials. Licensed machinists and maintenance technicians reach for this tap when fine-pitch 0-80 threads are required in production or repair work.

The K008005AS is suited for through-hole tapping in light-duty machining, fixture work, and precision assembly where 0-80 UNF threads are specified. Its compact size and right-hand thread direction make it appropriate for use in drill presses, CNC machining centers, and tapping fixtures. Typical applications include threading small bores in instrument housings, electronics hardware, and mechanical components where fine-pitch engagement is critical.

Key Features

• Spiral point geometry pushes chips forward for clean through-hole tapping
• High speed steel construction provides durability across a range of workpiece materials
• Plug chamfer allows gradual thread engagement and reduced starting torque
• H1 thread limit delivers consistent 3B class fit tolerances
• Bright finish with no coating for straightforward performance in general-purpose threading
• Right-hand thread direction, standard for 0-80 UNF applications

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for applications requiring 0-80 UNF right-hand internal threads in through-hole configurations with a 3B class of fit.

Installation Notes

This tap is installed by machinists and tool-and-die professionals using a tapping handle, drill press, or CNC tapping cycle with appropriate speed and feed for the workpiece material. Always ensure the pilot hole is drilled to the correct tap drill size for a 0-80 UNF thread before tapping. Apply cutting fluid compatible with the workpiece material to extend tool life and improve thread finish. Do not reverse the tap under power without confirming the machine setup supports reversing cycles, as breakage risk is elevated in small-diameter taps.
