Tap (gwintownik) FANAR M9 NGMM/3 DIN-352 HSS 6H — metric M9 cutting tool

FANAR M9 NGMM/3 DIN-352 HSS is a machine tap designed for cutting internal metric M9 threads. Manufactured from high-speed steel (HSS) and produced to DIN‑352 dimensions, this cutting tool is intended for production threading in metalworking environments. The tap is ground and shaped for use in machine tapping operations, offering a 6H tolerance class suitable for standard metric fits in steel and similar materials.

Advantages

The HSS material provides good toughness and wear resistance for general-purpose threading tasks. Conformity with DIN‑352 ensures dimensional accuracy and interchangeability in machine applications. The 6H tolerance class makes the tap suitable for commonly required thread clearances and fits. Its design is adapted for machine tapping, enabling consistent thread quality and repeatable results in batch production or repair work.

Suitable for

• Production threading of internal metric M9 threads in steel and similar metals
• Machine tapping using tapping heads, tapping machines or die grinders adapted for machine taps
• Batch manufacturing and repair or maintenance operations requiring repeatable thread quality

Key specifications

• Thread size: metric M9
• Standard: DIN‑352 (machine tap)
• Material: high-speed steel (HSS)
• Tolerance class: 6H
• Intended use: internal threading (machine tap)

How to use

Secure the tap in an appropriate machine tapping holder or collet, ensuring correct alignment with the workpiece. Use suitable cutting fluid for the work material to reduce friction and improve tool life. Start tapping at low speed to establish the thread, then use the machine's recommended feed to produce the full thread depth. Retract the tap periodically if machining long holes to clear chips and avoid breakage. Inspect threaded holes for dimensional conformity after tapping.

Usage recommendations

Use cutting fluid recommended for steel, maintain correct machine alignment, and follow appropriate spindle speed and feed rates for the material being machined. Replace the tap when wear or damage affects thread quality to ensure consistent results.
