Thread Tap FANAR M12 DIN 376B (6H) HSSE HL INOX

Solid thread tap FANAR M12 DIN 376B (6H) HSSE HL INOX is designed for creating precise internal M12 threads according to the DIN 376B profile with 6H tolerance. Manufactured from high-speed steel with cobalt (HSSE) and finished with a high-lubricity (HL) coating adapted for use in stainless steels (INOX), this tap is suitable for both manual and machine tapping operations in metalworking and maintenance environments where consistent thread quality and wear resistance are required.

Advantages

This FANAR M12 tap combines the hardness and heat resistance of HSSE with a high-lubricity surface layer that reduces friction and improves chip evacuation when cutting stainless steels. The DIN 376B geometry delivers accurate thread form and flank contact compatible with standard M12 fasteners, while the 6H tolerance ensures a reliable fit for general industrial and assembly applications. The solid construction supports regrinding and repeated use under appropriate conditions.

Suitable for

• Creating internal M12 threads in stainless steel (INOX) components
• Manual tapping with a wrench or machine tapping in lathes and milling machines
• Maintenance, repair and overhaul tasks in industrial environments
• Production runs requiring consistent thread tolerances and repeatability

How to use

Ensure the workpiece material and hole size are appropriate for an M12 DIN 376B tap and that the pilot hole is drilled to the recommended diameter for through or blind holes. Use suitable cutting fluid for stainless steel to minimize work hardening and improve chip flow. For manual tapping, apply steady axial pressure and reverse the tap periodically to break chips. For machine tapping, use appropriate spindle speeds and feed rates for HSSE tooling and stainless material, and ensure rigid clamping to avoid deflection. Clean chips from flutes frequently and inspect the thread for correct fit and tolerance after cutting.

Использование — рекомендации

For best results in stainless steel, use a lubricant formulated for INOX machining, maintain moderate cutting speeds to prevent work hardening, and replace or regrind the tap when wear affects thread quality. Store the tool dry and protected to preserve the HL surface.
