Hertel K008192AS25 Straight Flute Tap 8-32 Unc Hss Tin

Product Description

The HERTEL K008192AS25 is a straight flute tap designed to cut internal 8-32 UNC threads in a wide range of materials. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this tap delivers improved wear resistance and longer tool life compared to uncoated alternatives. The plug chamfer style provides a gradual thread lead-in, making it well suited for through-hole tapping applications. With 4 flutes and a right-hand thread direction, it is a standard configuration recognized by machinists and maintenance technicians across production and repair settings. Overall length is 2.125 inches with a thread length of 0.75 inches.

This tap is used in machine shops, MRO facilities, and field maintenance operations where 8-32 UNC threaded holes are required. It is appropriate for use in ferrous metals, aluminum, and similar machinable materials in both manual and CNC tapping setups. The TiN coating makes it a practical choice when running higher cycle counts or working with abrasive materials. It is sold individually and is suitable for use with standard tap wrenches or machine tap holders.

Key Features

• 8-32 UNC thread form with right-hand thread direction
• Plug chamfer for gradual thread engagement in through-hole applications
• High-speed steel construction for durability across a range of machinable materials
• Titanium nitride (TiN) coating for enhanced wear resistance and extended tool life
• 4-flute straight flute geometry for clean chip formation
• 2B class of fit and H3 thread limit for standard tolerance threading

Compatibility

Designed as an OEM-style replacement or direct-use tap for any application requiring 8-32 UNC internal threads at a 2B class of fit with H3 thread limit tolerance.

Installation Notes

This tap is installed by a machinist or maintenance technician using a standard tap wrench or machine tap holder. Always ensure the workpiece is securely clamped and the tap is properly aligned before beginning the threading operation. Apply appropriate cutting fluid to reduce heat and improve thread quality. Do not force the tap through the material — back off periodically to break chips and prevent tap breakage.
