Thread Tap FANAR M6 x 0.75 DIN 371C R40 (6H) HSSE TN 800X

FANAR thread tap M6 x 0.75 DIN 371C R40 (6H) HSSE TN 800X is a metric cutting tool designed to create internal threads with the DIN 371C profile. Manufactured from high-speed steel with additional cobalt content (HSSE) and finished with TN 800X coating, this tap is intended for use in both hand and machine tapping operations on through and blind holes in a variety of metals. The R40 (6H) tolerance marking denotes the intended fit for metric internal threads.

Advantages

The HSSE material provides improved wear resistance and hardness compared with standard high-speed steel, while the TN 800X coating reduces friction and increases tool life under elevated cutting temperatures. The DIN 371C geometry ensures consistent thread form and engagement, and the tap is suitable for precision threading where repeatability and dimensional accuracy are important. Its design supports both manual and machine operation for flexible shop use.

How to use

Select the appropriate drill size for the M6 x 0.75 core hole and secure the workpiece. For machine tapping, use correct spindle speed and feed to match the material and tool size; for hand tapping, use a suitable tap wrench and maintain perpendicular alignment to avoid thread distortion. Apply an appropriate cutting fluid for the workpiece material to reduce heat and aid chip evacuation. Reverse the tap periodically to clear chips when cutting deeper threads, and inspect threads after tapping for dimensional conformity.

Использование и рекомендации

Use recommended cutting speeds and feeds for the workpiece material, maintain lubrication appropriate to the metal being tapped, and replace the tap when wear or damage is detected to preserve thread quality and dimensional accuracy.
