Tap FANAR M7 NGMM/1 DIN-352D (6H) HSS for threading

FANAR M7 NGMM/1 DIN-352D (6H) HSS tap is a precision tool for cutting internal metric threads with nominal size M7. Manufactured to DIN 352D dimensions and tolerances, this HSS tap is suitable for both hand and machine tapping operations. The tool is intended for creating accurate M7 threads in compatible materials and is designed for workshop and industrial environments where repeatable, standard-compliant thread quality is required.

Advantages

The HSS construction provides wear resistance and toughness appropriate for general-purpose threading in a range of materials. Compliance with DIN 352D ensures dimensional accuracy and interchangeability with standard metric fasteners. The NGMM/1 geometry and 6H tolerance class deliver consistent thread fit and reliable engagement with mating bolts or screws. The tool is suitable for use in both manual tapping and machine tapping setups, offering versatility for different production contexts.

Suitable for

• Cutting internal metric M7 threads in metalworking and mechanical assemblies
• Workshop repairs and maintenance requiring standard-compliant threads
• Small-batch and production tapping operations using hand or machine taps

Key specifications

• Thread size: M7 (metric)
• Standard: DIN 352D
• Tolerance class: 6H
• Material: high-speed steel (HSS)
• Geometry/type: NGMM/1 (general-purpose taper/second/plug style according to DIN designation)
• Intended use: hand and machine tapping

How to use

Select an appropriate pilot hole diameter for M7 threads according to standard drill-tap charts, secure the workpiece, and align the tap square to the hole axis. For manual tapping, use a tap wrench and apply steady, even pressure while turning; reverse the tap periodically to break chips. For machine tapping, set correct spindle speed and feed compatible with the workpiece material and use appropriate tapping lubrication. Inspect formed threads for correct fit with metric M7 fasteners.

Usage recommendations

Use suitable cutting fluid for the workpiece material to extend tool life and improve surface finish. Start with a proper drill size for the M7 tap, maintain alignment to avoid premature tool wear or thread distortion, and apply periodic chip clearing when tapping ductile materials. Store the tap in a protective holder to prevent damage to the cutting edges.
