Thread tap FANAR M24x2 DIN-374C R40 (6H) HSSE 800 – cutting tool for M24x2 threads

FANAR thread tap M24x2 DIN-374C R40 (6H) HSSE 800 is a precision cutting tool designed to produce internal metric threads with M24x2 pitch. Manufactured to DIN 374C standards and rated for 6H tolerance class, this tap is made from HSSE 800 high-speed steel to provide enhanced hardness and improved wear resistance compared with standard high-speed steels. It is suitable for both hand and machine tapping operations in a range of metals commonly encountered in repair, maintenance and production environments.

Advantages

This FANAR tap offers consistent thread geometry conforming to DIN 374C and 6H tolerance for reliable fit with standard mating fasteners. The HSSE 800 material increases tool life and maintains cutting performance under elevated loads, while the R40 design delivers appropriate flute geometry and chip evacuation for general-purpose metal tapping. The tool is balanced for use in manual tapping as well as with tapping heads or machines, providing versatility across workshop applications.

Suitable for

• Creating internal M24x2 metric threads in metal components
• Repair and maintenance of threaded holes on machinery and assemblies
• Production environments requiring DIN 374C / 6H compliant threads
• Hand tapping and machine tapping operations

How to use

Select the correct drill size for the M24x2 tap according to standard tapping charts, secure the workpiece, and ensure proper alignment of the tap with the hole axis. For hand tapping, use an appropriate tap wrench and apply steady, even torque while turning the tap forward, then reverse periodically to break and clear chips. For machine tapping, set correct spindle speed and feed to match material and tap type, and use appropriate tapping holders or tapping heads to maintain alignment. Use a suitable cutting fluid or lubricant recommended for the workpiece material to improve chip formation and extend tool life.

Usage recommendations

For best results, verify drill diameter and thread allowance before tapping, maintain good chip evacuation especially in through holes or deep blind holes, and replace the tap when wear or dulling affects thread quality. Match cutting lubricant to the workpiece material and observe safety measures when using machine tapping equipment.
