Hertel K010456AS Thread Forming Tap M6x1 Plug Hss

Product Description

The HERTEL K010456AS is a metric thread forming tap designed for creating internal M6x1 threads in through-hole applications. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger threads with no chips to clear. This tap is manufactured from high-speed steel with a bright, uncoated finish. It features a plug chamfer with 3 to 5 chamfered threads for gradual thread engagement. The overall length is 2.5 inches and the thread length is 1 inch. It is suited for use in ductile metals and is installed by machinists, tool and die tradespeople, and maintenance technicians working with metric fastener standards.

This tap is intended for through-hole threading in metric applications where a plug chamfer start is appropriate. The plug chamfer provides a balance between the starting ease of a taper tap and the bottoming capability of a bottoming tap, making it a general-purpose choice for production and maintenance threading operations. The D8 thread limit designation indicates the tolerance class, which is relevant when matching thread fit to mating fastener specifications.

Key Features

• Thread forming design displaces material rather than cutting, producing stronger threads with no chip evacuation required
• M6x1 metric thread size with right-hand thread direction
• Plug chamfer with 3 to 5 chamfered threads for gradual thread engagement
• High-speed steel construction for durability in ductile metal applications
• D8 thread limit for controlled tolerance fit to mating fasteners
• No coolant-through feature; suited for conventional tapping with applied cutting fluid

Compatibility

Designed as a standard metric thread forming tap for through-hole M6x1 threading operations in ductile materials; consult tap drill charts for the correct forming tap hole diameter prior to use.

Installation Notes

Thread forming taps require a specific pre-drilled hole diameter that is larger than the equivalent cutting tap drill size; use the correct forming tap drill chart to avoid tap breakage or out-of-tolerance threads. Secure the workpiece and use a calibrated tap wrench or tapping head with appropriate tapping fluid for the workpiece material. Ensure the tap enters the hole perpendicular to the workpiece surface to maintain thread straightness. Follow applicable shop safety procedures and machine guarding requirements when power tapping.
