Tap FANAR M5 x 0.5 NGMM/2 DIN 2181 (6H) HSS – thread cutting tap M5x0.5

FANAR M5 x 0.5 NGMM/2 DIN 2181 (6H) HSS is a hand/plug tap engineered to cut metric fine threads M5×0.5 with precision. Manufactured from high-speed steel (HSS) and produced to DIN 2181 geometry with 6H tolerance class, this tap is intended for creating and repairing fine internal threads in a range of metals and alloys. The tool is suitable for workshop use, maintenance tasks and small-series production where controlled, accurate M5 fine threads are required.

Advantages

Made of HSS, the tap offers good wear resistance and maintains cutting performance across repeated use. Conformance to DIN 2181 geometry and 6H tolerance ensures consistent thread form and dimensional accuracy. The NGMM/2 flute and plug tap design balance chip control and thread finishing quality for common workshop materials. Its compatibility with standard hand tap tools makes it practical for repair and maintenance operations.

Suitable for

• Cutting M5×0.5 fine internal threads in steel and non-ferrous metals
• Maintenance and repair of mechanical assemblies requiring M5 fine threads
• Small-series production and prototyping where metric fine threads are needed
• Use with hand tap wrenches or tap holders in manual operations

When it may not be suitable

This hand/plug tap is not intended for high-speed, long-production runs where machine taps or carbide taps would offer greater durability and cycle time efficiency. It may also be unsuitable for extremely hard or abrasive materials beyond the typical working range of general-purpose HSS taps without appropriate coolants or specialized coatings.

Key specifications

• Thread size and pitch: M5 × 0.5 (metric fine)
• Material: High-speed steel (HSS)
• Tap type: NGMM/2 plug (hand) tap
• Standard geometry: DIN 2181
• Tolerance class: 6H
• Intended use: Internal thread cutting in metals and alloys

How to use

Secure the workpiece and ensure the drilled hole matches the recommended drill size for M5×0.5 before tapping. Use a suitable hand tap wrench or tap holder, align the tap square to the hole, and apply steady forward pressure while turning clockwise to cut the thread. Back off periodically to break chips and clear the flutes. Use cutting fluid appropriate for the workpiece material to improve tool life and thread finish. After reaching the required depth, reverse the tap to remove it, clean the thread of swarf and inspect the thread for fit and finish.

What to consider before purchase

• Verify the required thread size is M5×0.5 and that a 6H tolerance fits the application
• Confirm the tapped material is suitable for HSS tools or whether a coated or carbide tap is preferable
• Ensure you have the proper drill size, tap wrench and cutting fluid for manual tapping
• Consider whether plug (hand) tap geometry is appropriate versus taper or bottoming taps for your depth and thread start requirements

Usage recommendations

For best results, use a correctly sized drilled hole, apply suitable cutting fluid, and work at controlled manual speeds. Periodic backing out to clear chips extends tool life and improves thread quality. For high-volume or hard-material applications, evaluate machine or specialty taps as alternatives.
