Thread Tap FANAR M27x2 NGMM/2 DIN-2181 (6H) HSS

FANAR M27x2 NGMM/2 DIN-2181 (6H) HSS is a solid high-speed steel thread tap designed for cutting internal metric threads with a nominal size of M27 and a 2.0 mm pitch. Manufactured to DIN‑2181 tolerance 6H, this tap is suitable for standard industrial and workshop threading tasks. The NGMM/2 geometry provides reliable flute form and chip evacuation for a range of ferrous and non-ferrous materials when used with appropriate cutting fluid and machining parameters.

Advantages

This HSS tap offers consistent thread form accuracy thanks to DIN‑2181 tolerance 6H manufacturing, ensuring interchangeability and correct fit for mating threaded parts. Solid high-speed steel construction provides good wear resistance and toughness for general-purpose threading operations. The NGMM/2 flute geometry balances cutting performance and chip clearance, reducing the risk of clogging in through and blind holes when applied correctly.

Suitable for

• Machining internal metric threads M27 x 2 in steel and cast materials
• Workshop and industrial handheld or machine tapping operations
• Through-hole and blind-hole threading depending on setup and clearance
• Repair and maintenance tasks requiring replacement or re-cutting of worn threads

When it may not be suitable

This tap is made of high-speed steel and is intended for general-purpose threading; it may not be optimal for very hard or abrasive materials where carbide or coated taps are recommended. For production applications with extremely high cycle counts or where maximum tool life is required, a coated or carbide tool may offer better performance.

Key specifications

• Thread size: M27
• Pitch: 2.0 mm
• Material: high-speed steel (HSS), solid
• Tolerance: DIN‑2181 6H
• Flute/geometry: NGMM/2
• Application: internal metric threading, suitable for through and blind holes depending on tap style

How to use

Secure the workpiece and select appropriate tapping equipment (hand tap wrench or machine tapping holder). Use correct alignment to avoid cross-threading and apply a suitable cutting fluid for the work material to improve chip evacuation and reduce friction. Start the cut with light pressure, advance steadily, and periodically reverse the tap to break chips if tapping blind holes. Follow standard safety and machine operating procedures while performing tapping operations.

What to consider before purchase

• Verify required thread size and pitch (M27 x 2) and compatibility with mating parts
• Confirm material to be machined and whether HSS is suitable for that material
• Check whether a through‑hole or blind‑hole tap is required for your application
• Ensure the chosen tap shank and drive style match your tapping equipment

Usage recommendations

For best results, use cutting fluid appropriate to the work material, maintain proper tool alignment, and select correct spindle speed and feed when machine tapping. Replace the tap if signs of wear or chipping appear to maintain thread quality and part fit.
