Thread tap FANAR M12 DIN 376B EL (6H) HSSE TN 800X

FANAR thread tap M12 DIN 376B EL (6H) HSSE TN 800X is a long-length metric hand tap designed for cutting internal M12 threads to DIN 376B tolerance class 6H. Made from high-speed steel with cobalt and titanium nitride (HSSE TN), the tool is intended for use in metalworking environments where accurate, repeatable M12 internal threads are required. The tap suits both machine tapping operations and compatible hand tapping fixtures when correct tooling and alignment are used.

Advantages

The HSSE TN material offers improved wear resistance and heat tolerance compared with standard high-speed steel, extending tool life under heavier cutting conditions. The extended length (EL) design provides deeper reach and better access in applications with recessed holes or components that limit tool approach. Manufactured to DIN 376B dimensional and form standards and produced with a 6H tolerance, the tap delivers consistent thread geometry and high interchangeability with standard M12 threaded parts.

Suitable for

• Cutting internal M12 metric threads in ferrous metals and some non-ferrous alloys
• Production runs on tapping machines where repeatability is required
• Repair and maintenance work requiring replacement or re-threading of M12 holes
• Applications with recessed or hard-to-reach threaded bores due to extended length

Key specifications

• Thread size: M12 (metric)
• Standard: DIN 376B
• Tolerance class: 6H (internal thread tolerance)
• Material: HSSE with titanium nitride coating (HSSE TN)
• Design: extended length (EL) for deep or recessed holes
• Intended use: cutting internal metric threads

How to use

Select appropriate machine settings or hand-tapping approach for the workpiece material, ensuring correct alignment of the tap with the hole axis. Use suitable cutting fluid to reduce friction and prolong tool life when machining metals. For machine tapping, secure the workpiece and set feed and spindle speed according to material recommendations; for hand tapping, use a proper tap wrench and apply steady, controlled rotational motion while reversing occasionally to break and clear chips. Inspect thread quality after tapping and deburr as necessary.

Usage recommendations

Use cutting fluid appropriate for the workpiece material, avoid excessive spindle speeds that can overheat the tool, and ensure rigid setup to minimize runout. Replace the tap when wear or damaged flutes affect thread quality.
