Hertel K008155AS Spiral Point Tap 6-32 Unc Hss

Product Description

The HERTEL K008155AS is a spiral point tap designed for cutting 6-32 UNC internal threads in through-hole applications. Built from high-speed steel with a bright uncoated finish, it delivers reliable performance across a range of workpiece materials. The spiral point design pushes chips ahead of the tap and out through the bottom of the hole, reducing the risk of chip packing in through-hole drilling operations. With an H1 thread limit, this tap holds close tolerances suitable for standard UNC thread fits. It has a 2-flute configuration, an overall length of 2 inches, and a thread length of 0.6875 inches. Machinists and tool-and-die professionals rely on this tap for production tapping in vertical drill presses, CNC machining centers, and tapping machines.

This tap is suited for through-hole tapping in light-duty to medium-duty applications, including sheet metal fabrication, machine assembly, and fixture building. The 6-32 UNC thread size is common in small fastener and electronics assembly applications. The right-hand cut and plug chamfer make it a standard choice for powered tapping setups where axial thrust assists chip evacuation. It is not designed for blind-hole applications where chip packing would be a concern.

Key Features

• 6-32 UNC thread form with plug chamfer for through-hole tapping
• High-speed steel construction for durability across a broad range of materials
• Spiral point geometry pushes chips forward, reducing packing in through-hole operations
• H1 thread limit for consistent, close-tolerance UNC thread production
• Bright uncoated finish — suitable for use with cutting fluid on ferrous and non-ferrous materials
• Right-hand cut compatible with standard tapping heads and CNC rigid tapping cycles

Compatibility

Designed as an OEM-style replacement or production tap for use in standard machine tool setups requiring 6-32 UNC through-hole threading.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Always use an appropriate cutting fluid or tapping compound matched to the workpiece material to extend tap life and improve thread quality. Secure the workpiece firmly before tapping and ensure the drill press or tapping machine spindle is properly aligned to avoid tap breakage. Replace worn taps before thread quality degrades to prevent scrap parts.
