Tap (threading tool) FANAR M2 NGMM/3-P DIN 352 (6HX) HSS-E TiN for stainless steel

FANAR M2 NGMM/3-P DIN 352 (6HX) HSS-E TiN for stainless steel is a machine tap engineered for producing M2 metric threads in stainless steel and similar materials. Made from high-speed steel with cobalt (HSS‑E) and finished with a titanium nitride (TiN) coating, this tap follows DIN 352 standards and uses a 3‑piece cutting geometry (NGMM) with 6HX tolerance to support consistent, production-oriented threading and routine maintenance work.

Advantages

The HSS‑E material provides enhanced heat resistance and toughness compared with standard high-speed steel, while the TiN coating reduces friction and extends tool life when cutting stainless steel. The NGMM 3‑piece cutting geometry promotes efficient chip formation and evacuation, and the 6HX tolerance ensures reliable thread fit in assembly applications. Manufactured according to DIN 352, the tap offers repeatable dimensional accuracy suitable for production environments.

Suitable for

• Producing internal M2 metric threads in stainless steel and austenitic alloys
• Workshop and maintenance threading operations on metal components
• Small‑part production runs and batch manufacturing requiring consistent thread quality

When it may not be suitable

This tap is designed specifically for M2 metric threads; it is not suitable for other thread sizes or for producing external threads. For non‑ferrous soft materials or plastics, a tap with a geometry and coating optimized for those materials may perform better. Extremely interrupted cuts or heavily built‑up edge conditions may require specialized coatings or ground geometries beyond the NGMM design.

Key specifications

• Thread size: M2 metric
• Material: high‑speed steel with cobalt (HSS‑E)
• Coating: titanium nitride (TiN)
• Standard: DIN 352
• Cutting geometry: NGMM 3‑piece
• Tolerance class: 6HX
• Intended workpiece material: stainless steel and similar alloys

How to use

Select the correct drill size and prepare the hole according to recommended drilling practice for M2 threads in stainless steel. Secure the workpiece and align the tap in the spindle or tap holder. Use appropriate cutting fluid for stainless steel and apply steady feed while maintaining correct rotational direction. Withdraw the tap periodically to clear chips and prevent clogging; reverse slightly if tap binds. Follow machine and tooling manufacturer recommendations for speeds and feeds to avoid premature wear.

What to consider before purchase

• Confirm you require an M2 internal metric tap and that M2 is the correct thread size for your assembly
• Ensure your application involves stainless steel or similar alloys suited to HSS‑E with TiN coating
• Verify compatibility with your tapping holder or machine spindle and the required tap shank or mounting
• Consider the production volume to decide if a coated HSS‑E tap meets durability needs or if other materials/coatings are preferable

Usage recommendations

Use cutting fluid formulated for stainless steel, moderate spindle speeds, and controlled feed to maximize tool life. Regularly inspect the tap for wear and replace when thread quality degrades to maintain consistent M2 thread performance.
