Thread Tap FANAR M8 DIN 376C (6H) HSSE TN 800X

FANAR Thread Tap M8 DIN 376C (6H) HSSE TN 800X is a precision tool designed for cutting internal metric threads M8 in metalworking applications. Manufactured to DIN 376C standard with a 6H tolerance class, this tap is produced from high-speed steel with cobalt (HSSE) for improved hardness and wear resistance and finished with a TN (titanium nitride) coating to reduce friction and extend tool life. The geometry and coating make it suitable for reliable thread production in production, maintenance and repair environments where consistent M8 internal threads are required.

Advantages

The HSSE material provides higher hot hardness and better durability compared with conventional high-speed steel, while the TN coating reduces friction and helps prevent built-up edge during threading. Conformance to DIN 376C and 6H tolerance ensures dimensional accuracy and interchangeability of produced threads. The tap's construction supports stable cutting performance, consistent thread form and longer service intervals, reducing the frequency of tool changes in repetitive operations.

Suitable for

• Cutting M8 internal threads in steel and alloyed steels
• Serial production where consistent thread quality is required
• Maintenance and repair tasks that require precise metric M8 threads
• Workpieces with small or medium hole depths compatible with DIN 376C taper tap geometry

Key specifications

• Thread size: M8 (metric)
• Standard: DIN 376C taper tap geometry
• Tolerance class: 6H
• Material: HSSE (high-speed steel with cobalt)
• Surface finish: TN (titanium nitride) coating
• Intended use: internal thread cutting for metalworking

How to use

Select a correctly sized pilot hole according to M8 thread standards and secure the workpiece. Use appropriate threading lubricant to reduce heat and wear on the tap. Start the tap straight into the hole and apply even axial pressure while turning; when cutting full threads, periodically reverse the tap slightly to break chips and clear the flutes. Inspect the thread quality after cutting and replace the tap if wear or damage affects thread accuracy.

Usage recommendations

Use cutting fluid suitable for the workpiece material and monitor tap wear during serial operations. For hardened or abrasive materials, verify suitability of HSSE with TN coating and consider step drilling or specialized tooling if necessary. Store taps in a dry, protected location to preserve the coating and cutting edges.
