Tap (threading tool) FANAR TAP M 8 NGMM DIN-352 INOX

FANAR TAP M 8 NGMM DIN-352 INOX is a threading tap intended for cutting M8 metric internal threads to DIN 352 specifications. Designed with NGMM geometry and produced for use in stainless steel (INOX), this tap is suitable for both hand and machine tapping in repair, fabrication and general metalworking where accurate, durable M8 threads are required.

Advantages

The NGMM geometry provides improved chip control and reduced cutting forces when working with stainless steel, while the DIN-352 form ensures consistent thread profile and pitch. The tool material and coating are selected to resist galling and wear in demanding INOX applications, supporting longer tool life and repeatable thread quality. Its size and design allow for compatibility with common tapping machines as well as manual tap holders.

Suitable for

• Cutting M8 internal metric threads in stainless steel (INOX)
• Machine tapping and manual tapping operations
• Maintenance, repair and overhaul (MRO) work
• Metal fabrication and assembly where DIN-compliant threads are required

When it may not be suitable

This tap is specifically intended for M8 threads and stainless steel applications; it is not appropriate for creating threads of other diameters or for use in highly abrasive or non-metal materials where a different geometry or material would be preferable. For soft materials or thin-walled parts, a tap designed for reduced cutting forces or forming taps may give better results.

Key specifications

• Thread size: M8 metric
• Geometry: NGMM
• Standard: DIN 352 thread form
• Material suitability: stainless steel (INOX)
• Application: manual and machine tapping

How to use

Select the appropriate pilot hole diameter for M8 threads and secure the workpiece to prevent movement. For machine tapping, set appropriate spindle speed and feed to match stainless steel cutting conditions; for manual tapping, use suitable tap wrench or holder and apply steady, even pressure while turning. Use cutting fluid compatible with INOX to improve chip evacuation and reduce heat and galling. Back the tap periodically to break chips and clear the flutes.

What to consider before purchase

• Confirm that M8 thread size and ISO/DIN thread form meet the assembly requirements
• Ensure suitability for stainless steel workpieces and intended tapping method (manual or machine)
• Verify machine compatibility and required pilot hole diameter
• Consider availability of appropriate cutting fluids and tap holders for INOX tapping

Usage recommendations

Use a correct pilot hole, steady feed and proper cutting fluid when tapping stainless steel to minimize galling and extend tool life. For production runs, monitor thread quality and replace the tap at first signs of wear to maintain consistent M8 thread accuracy.
