Hertel K011205AS Spiral Point Tap 8-32 Unc 2 Flutes

Product Description

The HERTEL K011205AS is a spiral point plug tap designed for cutting 8-32 UNC right-hand threads in through-hole applications. Made from high-speed steel with a bright uncoated finish, it features 2 flutes and a plug chamfer that pushes chips ahead of the tap and out through the exit side of the hole. The H4 thread limit provides a controlled fit tolerance suitable for standard UNC fastener assemblies. With a 0.168 inch shank diameter and a 0.75 inch thread length, this tap is suited for light to medium workpiece thicknesses commonly encountered in machine shop, maintenance, and repair operations.

This tap is used for tapping 8-32 UNC threaded holes in through-hole configurations in materials including steel, aluminum, brass, and similar machinable metals. It is a common tool in production machining, job shops, maintenance facilities, and field repair environments where 8-32 machine screw threads are required. The spiral point geometry makes it particularly effective in CNC tapping operations and drill press setups where chip control is a priority.

Key Features

• 8-32 UNC thread form for standard machine screw applications
• Spiral point geometry pushes chips forward, ideal for through-hole tapping
• High-speed steel construction provides durability across a range of machinable metals
• H4 thread limit for controlled tolerance fit with standard UNC fasteners
• Plug chamfer for easy thread entry and smooth cutting action
• Bright uncoated finish suitable for general-purpose use with cutting fluid

Compatibility

Designed as a general-purpose replacement or standard-stock spiral point tap for through-hole 8-32 UNC threading operations across production and maintenance applications.

Installation Notes

This tap is installed and operated by machinists, maintenance technicians, and toolroom professionals using a tap wrench, tapping head, or CNC tapping cycle. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Ensure the tap is properly aligned with the drilled hole before applying torque to prevent tap breakage. Use the correct tap drill size for 8-32 UNC as specified in standard machining references before tapping.
