FANAR M25x1.5 NGMM/2 DIN-2181 (6H) HSS is a machine tap designed for cutting precise internal metric threads M25 with a 1.5 mm pitch. Manufactured according to DIN-2181 standards and made from high-speed steel (HSS), this tap provides the rigidity and wear resistance required for repeated machining operations. The NGMM/2 geometry and 6H tolerance ensure compatibility with standard metric fits and reliable thread form in suitable materials.
Advantages
The high-speed steel construction offers good hardness and edge retention for longer tool life under typical tapping conditions. Compliance with DIN-2181 and a 6H tolerance class deliver dimensional accuracy and interchangeability with mating parts. The NGMM/2 flute and chamfer geometry are optimized for conventional machine tapping, providing consistent chip formation and reduced risk of thread distortion when used in recommended materials and machining setups.

How to use
Secure the workpiece and align the tap with the pre-drilled hole matching the recommended drill size for M25×1.5. Use a rigid machine setup or appropriate tapping holder to maintain concentricity. Apply suitable cutting lubricant and feed the tap at a steady rate, reversing periodically to break chips if required by material or flute type. Follow machine manufacturer and tooling supplier guidance for spindle speed and feed to avoid overload and ensure proper thread form.
Использование и рекомендации
Для повышения срока службы и качества резьбы используйте рекомендованные режимы резания, подходящие смазочно-охлаждающие жидкости и стабильную фиксацию заготовки. При обработке вязких или пружинистых материалов выбирайте прерывистый режим прокрутки и регулярную эвакуацию стружки.
FANAR M25x1.5 NGMM/2 DIN-2181 (6H) HSS is intended for precision internal thread cutting with a metric M25×1.5 profile. The tool follows DIN-2181 dimensional requirements and is produced from HSS to balance toughness and wear resistance during tapping operations. NGMM/2 geometry supports effective chip flow in standard machining conditions, making it suitable for a range of industrial tapping applications.
Advantages
The HSS material provides reliable performance across common workpiece materials and allows regrinding if needed. DIN-2181 compliance and a 6H tolerance ensure the threads meet standard fits for assembly. NGMM/2 flute design improves chip control and reduces the likelihood of jamming when used with correct lubrication and machine parameters.
Suitable for
- Cutting internal metric threads M25×1.5 in metal components
- Machine tapping on lathes, milling machines, and dedicated tapping heads
- Production and maintenance operations requiring standardized thread accuracy
Key specifications
- Thread size: M25
- Pitch: 1.5 mm
- Tolerance class: 6H
- Standard: DIN-2181
- Material: high-speed steel (HSS)
- Geometry: NGMM/2 flute/chamfer type
How to use
Drill the appropriate pilot hole for M25×1.5 and ensure the hole is free of burrs. Mount the tap in a suitable holder or machine spindle with correct axial alignment. Use cutting fluid appropriate for the workpiece material, advance the tap at controlled feed, and retract periodically if needed to clear chips. Inspect the thread after tapping and deburr edges if necessary.
Usage recommendations
Use recommended drill sizes, cutting oils, and machine settings for M25×1.5 taps. Keep the tap clean and inspect for wear; regrind or replace the tool when cutting performance deteriorates to maintain thread quality and dimensional accuracy.
FANAR M25x1.5 NGMM/2 DIN-2181 (6H) HSS ir izstrādāts iekšējo metrisku M25×1,5 vītņu griešanai.

Kā lietot
Izurbjiet piemērotu iepriekšējo caurumu priekš M25×1,5 un pārbaudiet, vai tas ir bez burriem. Nostipriniet tapu turētājā vai spindelī ar pareizu asiālajiem izlīdzinājumu. Lietojiet atbilstošu eļļošanu, rīkojieties ar vienmērīgu padevi un pēc vajadzības periodiski izvelciet tapu, lai izvadītu skaidu. Pārbaudiet vītni pēc operācijas un veiciet nepieciešamo noslīpēšanu vai noapaļošanu.
Lietošanas ieteikumi
Izmantojiet ieteiktos urbju izmērus, griešanas šķidrumus un tehniskos režīmus M25×1,5 tapām. Regulāri pārbaudiet instrumentu nolietojumu un, ja nepieciešams, pārgrieziet vai nomainiet tapu, lai saglabātu vītņu kvalitāti un izmēru precizitāti.
