Hertel K010457AS Thread Forming Tap M6x1 Bottoming Hss

Product Description

The HERTEL K010457AS is a metric thread forming tap designed for bottoming applications in blind hole threading operations. Made from high-speed steel with a bright uncoated finish, this tap cold-forms internal threads without cutting, producing stronger threads with less material removal. It carries a D8 thread limit and a right-hand thread direction, sized for M6x1 thread profiles. With an overall length of 2.5 inches and a thread length of 1 inch, it fits standard tap holders used by machinists and maintenance technicians working on precision assemblies and mechanical components.

This tap is suited for blind hole applications in metalworking and manufacturing environments where bottoming reach is required. The 1-2P chamfer length allows the tap to form threads close to the bottom of a blind hole, making it a practical choice for close-tolerance work in production shops, maintenance facilities, and job shops. It is installed using standard tap wrenches or machine holders compatible with the 0.255-inch shank diameter.

Key Features

• Thread forming design cold-forms threads without cutting chips, reducing tap breakage risk in blind holes
• M6x1 metric thread size with right-hand thread direction
• Bottoming chamfer (1-2P) for threading close to the bottom of blind holes
• High-speed steel construction provides durability across a range of workpiece materials
• D8 thread limit for consistent thread tolerance control
• Bright uncoated finish suitable for general-purpose metalworking applications

Compatibility

Designed for use in blind hole threading applications requiring M6x1 metric thread profiles. Compatible with standard tap holders and tap wrenches accepting a 0.255-inch shank diameter.

Installation Notes

Thread forming taps require a specific tap drill size larger than standard cut tap drill sizes — consult a thread forming drill chart for the correct pre-drill diameter for M6x1 before use. Lubrication is recommended during forming to reduce heat and extend tap life. Secure the workpiece and ensure proper alignment before driving the tap to avoid galling or tap breakage. This tap is intended for use by qualified machinists or maintenance technicians familiar with threading operations.
