Hertel K008196AS Straight Flute Tap 8-32 Unc Hss Bright

Product Description

The HERTEL K008196AS is a straight flute tap designed to cut 8-32 UNC internal threads in a wide range of materials. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-forming performance in ferrous and non-ferrous metals, plastics, and similar workpiece materials. The plug chamfer provides 3 to 5 lead threads, making it well suited for through-hole tapping applications where a gradual thread entry is preferred. With an overall length of 2.125 inches and a 2-flute straight-flute geometry, it is compatible with standard tap drivers, T-handle wrenches, and CNC tapping centers operating at appropriate feeds and speeds.

This tap is used in machine shops, maintenance and repair operations, and production environments where 8-32 UNC threaded holes are required. The 2B class of fit produces a standard commercial-tolerance thread appropriate for most fastener and assembly applications. The H3 thread limit designates a specific oversize tolerance above basic pitch diameter, which accommodates typical tool wear and plating allowances. This tap is appropriate for manual tapping as well as light-duty machine tapping setups where coolant-through capability is not required.

Key Features

• 8-32 UNC thread form with right-hand cutting direction
• Plug chamfer with 3 to 5 lead threads for gradual thread entry in through holes
• High-speed steel construction for durability across a range of workpiece materials
• H3 thread limit for consistent oversize tolerance control
• 2B class of fit meeting standard commercial thread tolerance requirements
• Bright uncoated finish suitable for general-purpose tapping without specialized lubricant requirements

Compatibility

Designed as a standard straight flute tap for use in through-hole applications requiring 8-32 UNC internal threads. Fits standard tap holders, T-handle wrenches, and machine tap chucks sized for this tap diameter and shank.

Installation Notes

Secure the workpiece firmly before tapping and ensure the tap is properly aligned perpendicular to the hole to prevent tap breakage and thread misalignment. Apply an appropriate cutting fluid or tapping oil for the workpiece material to extend tool life and improve thread quality. Use a calibrated torque-limiting tap driver when tapping by hand in harder materials to reduce the risk of breakage. Inspect the tap for chipping or wear before each use and replace when cutting torque increases noticeably or thread quality degrades.
