Tap (gwintownik) FANAR M10x1.25 NGMM/2 DIN 2181 (6H) HSS - A1-220001-0104

FANAR threading tap M10x1.25 NGMM/2 produced to DIN 2181 with 6H tolerance in high-speed steel (HSS) is intended for cutting internal metric threads M10×1.25. The tool is suitable for use with hand tapping or machine tapping operations and is designed to deliver consistent thread form and dimensional accuracy where DIN 2181 geometry and 6H tolerance are specified. The HSS material provides wear resistance and hardness appropriate for machining a variety of ferrous and non-ferrous metals in repair, maintenance and light production tasks.

Advantages

The FANAR M10x1.25 tap offers a standardized DIN 2181 profile and 6H tolerance for interchangeability and predictable fit with mating parts. Manufactured from HSS, it combines cutting edge durability with good toughness for moderate cutting speeds. Its NGMM/2 geometry provides reliable chip evacuation and reduced risk of tap breakage when used with appropriate tapping technique and lubrication. The design supports both manual and machine applications, facilitating versatile use across workshops and maintenance environments.

Suitable for

• Cutting internal metric threads M10×1.25 in metals
• Repair and maintenance of threaded holes
• Machine and hand tapping operations
• Applications requiring DIN 2181 geometry and 6H tolerance

Key specifications

• Thread size: M10×1.25
• Thread form: Metric, DIN 2181 geometry
• Tolerance: 6H
• Material: High-speed steel (HSS)
• Geometry: NGMM/2 (general-purpose metric tap geometry)
• Use: Suitable for hand and machine tapping

How to use

Select the correct drill size for the M10×1.25 tapped hole and secure the workpiece to prevent movement. For hand tapping, use a suitable tap wrench; for machine tapping, mount the tap in an appropriate holder or chuck. Apply cutting fluid or lubricant suitable for the workpiece material to improve chip flow and reduce heat. Start the tap straight into the drilled hole, advance with steady pressure and maintain alignment. For through-holes, use continuous rotation; for blind holes, use a back-and-forth motion to break chips and avoid jamming. After completing the thread, reverse the tap to remove it and clean the thread to remove chips and lubricant.

Usage recommendations

Use appropriate cutting speeds and feed for the workpiece material, ensure correct drill size before tapping, and apply suitable tapping lubricant. Inspect taps regularly for wear or damage and replace when cutting performance degrades to avoid poor thread quality or tap failure.
