FANAR tap M6 DIN 376B (6H) HSSE TN 800X – hand/spiral flute threading tool

FANAR tap M6 DIN 376B (6H) HSSE TN 800X – hand/spiral flute threading tool is a metric M6 internal threading tap made to DIN 376B tolerance class 6H. Constructed from high-speed steel (HSSE) with a titanium nitride (TiN) coating, this tap is suitable for both manual and machine tapping operations and is intended for producing accurate internal threads in steel and similar materials. The tool design and coating improve wear resistance and sliding during cutting while maintaining the dimensional accuracy required for maintenance, tooling and light production tasks.

Advantages

The HSSE base material provides high hot hardness and toughness for repeated tapping in medium-hard materials. The TiN coating reduces friction and increases surface hardness, extending tool life and helping to prevent galling when cutting steel. DIN 376B geometry and 6H tolerance ensure reliable thread form and fit for standard metric assemblies. The tap is sized specifically for M6 internal threads and is compatible with both hand-held tapping and machine-mounted operations, offering versatility across different workshop environments.

Suitable for

• Cutting M6 metric internal threads in steel and similar alloys
• Maintenance and repair work requiring replacement or renewal of internal threads
• Toolroom and jigging operations where standard DIN 376B threads are needed
• Small-batch production and prototype fabrication with manual or machine tapping

Key specifications

• Thread size: M6 metric internal thread
• Tolerance/fit: DIN 376B, tolerance class 6H
• Material: high-speed steel (HSSE)
• Coating: titanium nitride (TiN)
• Flute type: hand/spiral flute suitable for manual and machine tapping
• Application materials: steel and similar metallic alloys

How to use

Select an appropriate drill size for the M6 tap and prepare the workpiece by ensuring the hole is clean and free of chips. Secure the workpiece and align the tap perpendicular to the hole. For manual tapping, use a proper tap wrench and apply steady, even rotational force; back off periodically to break chips and avoid binding. For machine tapping, ensure correct spindle speed and feed, use suitable tapping holders if required, and provide adequate coolant or lubricant. After tapping, remove chips and inspect the thread for conformity to the required fit.

Usage recommendations

Use cutting fluid or lubricant appropriate for steel to extend tool life and improve surface finish. Avoid excessive feed or torque that can overload the tap; back off frequently when tapping deep holes to clear chips. Store taps in a dry, protected environment to preserve the TiN coating and cutting edges.
