Tap (gwintownik) FANAR M8 DIN 376C R15 HSSE PM TiCN coated

FANAR M8 tap (DIN 376C) is a hand and machine tapping tool designed to cut internal metric threads M8 with the R15 thread form and 6HX tolerance. Made from HSSE PM (high-speed steel with powder metallurgy) and finished with a TiCN coating, this tap is intended for use in general machining of steel and alloy materials in workshop and production environments. The tool geometry and coating are selected to balance cutting performance, wear resistance and tool life for repeated tapping operations.

Advantages

The HSSE PM substrate offers high hardness and toughness suited to interrupted and continuous cutting, while the TiCN coating increases surface hardness and reduces friction during cutting, which helps to extend tool life and maintain consistent thread quality. Conformity to DIN 376C ensures standard shank and thread form compatibility for fixtures and holders. The design supports both manual and machine tapping, giving flexibility for small-batch workshop jobs and medium-volume production runs.

Suitable for

• Cutting internal metric threads M8 in steel and alloy materials
• Hand tapping with appropriate handles and guides
• Machine tapping on lathes, mills or tapping heads
• Workshop repairs and production runs requiring DIN 376C R15 thread form and 6HX tolerance

Key specifications

• Thread form: R15
• Tolerance class: 6HX
• Standard: DIN 376C
• Material: HSSE PM (powder metallurgy high-speed steel)
• Coating: TiCN (titanium carbonitride)
• Application mode: manual and machine tapping

How to use

Select an appropriate drill size for the M8 thread and prepare the hole with correct perpendicularity and surface finish. Secure the workpiece to prevent movement. For manual tapping, use a suitable tap wrench and apply steady, even pressure, reversing periodically to break chips. For machine tapping, set correct spindle speed and feed for the material, ensure proper alignment in the holder, and use pecking or chip-breaking cycles where necessary. Use appropriate cutting fluid to improve chip evacuation and reduce heat, and inspect threads after tapping to confirm fit and tolerance.

Usage recommendations

Use corrosion-resistant cutting fluid for steel operations and avoid excessive axial force to reduce risk of tap breakage. Replace or regrind the tap when signs of wear or chipped cutting edges appear to maintain thread quality. For high-volume or hard material applications, consider machine tapping with rigid setup and controlled feeds to maximize tool life.
