Hertel K010340AS Thread Forming Tap 8-32 Unc Plug Hss

Product Description

The HERTEL K010340AS is a thread forming tap designed for creating internal threads in through-hole applications without cutting. Instead of removing material, it cold-forms threads by displacing metal, producing stronger threads with no chips. Built from high-speed steel with a bright, uncoated finish, this tap handles a wide range of ductile metals and softer alloys. The plug chamfer with 3 to 5 chamfered threads makes it suitable for through-hole threading where the tap can pass completely through the workpiece. Overall length is 2.125 inches, thread length is 0.75 inches, and the thread limit is H3.

This tap is used in machine shops, maintenance facilities, and light manufacturing environments where 8-32 UNC internal threads are required. The 2B class of fit is the standard commercial tolerance for most inch-series threaded fastener applications. It is well suited for production tapping in drill presses, CNC machining centers, and tapping heads. Right-hand thread direction applies. Machinists, tool and die makers, and maintenance technicians are the primary users.

Key Features

• Thread forming design displaces material instead of cutting, producing chip-free threads
• 8-32 UNC thread form with 2B class of fit for standard commercial tolerance
• Plug chamfer with 3 to 5 chamfered threads for through-hole applications
• High-speed steel construction for durability across ductile workpiece materials
• H3 thread limit for controlled thread tolerance output
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed for through-hole threading operations requiring 8-32 UNC internal threads at 2B class of fit. Compatible with standard tapping chucks and holders sized for a 0.168-inch shank diameter.

Installation Notes

Thread forming taps require a properly sized forming tap drill hole, which is larger than a standard cut tap drill - consult a thread forming drill chart for the correct hole size before use. Secure the workpiece and use appropriate tapping fluid or cutting oil rated for the workpiece material. Always ensure the tap is aligned perpendicular to the workpiece surface before engaging. This tool should be installed and operated by qualified machinists or maintenance technicians following standard shop safety procedures.
