Hertel K008203AS Spiral Point Tap 8-32 Unc 2 Flute Hss

Product Description

The HERTEL K008203AS is a spiral point tap designed to cut internal threads in through-hole applications. It features a plug chamfer and a two-flute spiral point geometry that pushes chips ahead of the tap and out of the hole, reducing clogging and improving thread quality. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, the tap is ground to an H2 thread limit, which provides a close tolerance fit suitable for most standard threaded fastener assemblies. It produces 8-32 UNC threads with a 3B class of fit, meeting standard internal thread tolerance requirements for inch-series unified coarse thread applications.

This tap is used in machine shops, maintenance facilities, and production environments where 8-32 UNC through-hole threading is required. The plug chamfer style makes it appropriate for general-purpose threading in materials such as mild steel, aluminum, and similar machinable metals. It is suited for use in drill presses, CNC machining centers, tapping heads, and hand tapping operations. The spiral point design performs best in through-holes where chips can advance freely through the workpiece.

Key Features

• Spiral point geometry pushes chips forward through the hole for cleaner cutting action
• 8-32 UNC thread form with 3B class of fit for standard inch-series through-hole applications
• H2 thread limit for controlled tolerance and consistent fit with mating fasteners
• High-speed steel construction provides durability across a range of machinable metals
• Plug chamfer with right-hand thread direction for conventional tapping operations
• Bright uncoated finish suitable for use with cutting fluids or tapping compounds

Compatibility

Designed as a standard replacement or production spiral point tap for applications requiring 8-32 UNC internal threads in through-hole configurations.

Installation Notes

Installation is performed by licensed machinists or qualified maintenance technicians. Always secure the workpiece before tapping and use an appropriate tapping fluid or cutting compound to extend tap life and improve thread finish. Back the tap out periodically to clear chips when tapping manually. Do not force the tap if resistance increases suddenly, as this may indicate chip buildup or incorrect drill hole size for the specified thread.
