## Summary description

FANAR thread tap M4 manufactured to DIN-376B standard, tolerance class 6H, made from HSSE material with TN 800X coating. Designed for cutting internal metric threads (M4) in metals and alloys, suitable for use in machine shops, maintenance and repair, and production environments requiring precision thread forming and cutting.

## Long description

FANAR thread tap M4 DIN-376B (6H) HSSE TN 800X is a precision cutting tool engineered to produce internal metric M4 threads according to the DIN-376B geometry and tolerance class 6H. Manufactured from high-speed steel with cobalt (HSSE) and finished with a TN 800X coating, this tap is intended for reliable thread cutting in a variety of metallic materials and alloys. Its design provides consistent thread form and dimensional accuracy suitable for machine-shop production, maintenance tasks and repair operations where repeatable results are required.
Advantages
The HSSE substrate offers increased hardness and heat resistance compared with standard high-speed steels, while the TN 800X surface coating improves wear resistance and reduces built-up edge during cutting. Compliance with the DIN-376B profile and 6H tolerance ensures interchangeability and predictable fit with mating fasteners. The combination of material and coating contributes to extended tool life and stable cutting performance across moderate to demanding production runs.
Suitable for
 Cutting internal M4 metric threads in steels and non-ferrous alloys
 Machine-shop production and small-series manufacturing
 Maintenance, repair and overhaul (MRO) applications
 Fixture and component assembly where standardized thread tolerance is required
Key specifications
 Thread size: M4
 Thread standard/profile: DIN-376B
 Tolerance class: 6H
 Material: High-speed steel with cobalt (HSSE)
 Surface finish: TN 800X coating for improved wear resistance
 Application: Cutting internal metric threads in metals and alloys
How to use
Secure the workpiece and ensure the drilled hole meets the recommended pilot diameter for an M4 thread according to DIN recommendations. Use appropriate cutting fluid for the material being machined to improve chip evacuation and reduce heat. Align the tap perpendicular to the hole, apply steady axial pressure and rotate the tap clockwise to cut the thread; periodically reverse slightly to break chips and prevent jamming. For production use, mount the tap in a suitable holder or machine spindle rated for hand or machine tapping as required.
Usage recommendations
Choose cutting speed and feed according to the workpiece material; use lower speeds for harder alloys and higher speeds for softer metals. Regularly inspect the cutting edges for wear and replace the tap when thread quality degrades. For blind holes, ensure proper chip evacuation and consider peck tapping cycles to avoid chip packing.
