Tap FANAR GWINTOWNIK M20x1,5 NGMF (6H) HSS – metric M20×1.5 thread, 6H fit, high-speed steel

FANAR GWINTOWNIK M20x1,5 NGMF (6H) HSS is a solid high-speed steel (HSS) tap designed to cut internal metric threads M20×1.5 with a 6H tolerance fit. Intended for both hand and machine tapping, this tool is suitable for a wide range of metalworking operations including workshop repairs, maintenance tasks and industrial assembly where durable HSS cutting tools are required.

Advantages

The tap is made from HSS which provides good hardness and wear resistance for cutting steel and similar metals. Its geometry is optimized for forming precise M20×1.5 threads with consistent 6H tolerance, ensuring reliable mating with standard metric bolts and components. The solid construction offers rigidity and repeatability in production or repair environments.

Suitable for

• Cutting internal metric threads M20×1.5 in steel and similar metals
• Hand tapping operations in workshops and maintenance
• Machine tapping on drill presses, tapping heads or CNC machines
• Industrial assembly where a 6H tolerance fit is required

Key specifications

• Thread size and pitch: M20 × 1.5
• Tolerance fit: 6H (internal thread tolerance)
• Material: high-speed steel (HSS), solid construction
• Type: general-purpose metric tap for internal threads
• Application method: suitable for hand and machine tapping

How to use

Select the proper drill size for the M20×1.5 tap drill before starting. Secure the workpiece and ensure alignment between the tap and the hole to prevent cross-threading. For hand tapping, use appropriate tap wrench and apply steady, even pressure while cutting; for machine tapping, set correct spindle speed and feed to match material and tap geometry. Use cutting fluid suitable for the workpiece material to improve chip evacuation and extend tool life. Regularly inspect the tool for wear and replace it when cutting performance deteriorates.

Usage recommendations

Use suitable cutting fluid and appropriate speeds/feeds for the base material to maximize tool life. When tapping deep holes, withdraw the tap periodically to clear chips. Store the tap in a dry place and protect the cutting edges from impacts.
