Thread Tap FANAR M12 DIN-376C R45 6H HSSE-PM S‑NC TiCN

FANAR thread tap M12 manufactured to DIN-376C standard with R45 chamfer and 6H tolerance. The tap is made from HSSE-PM (high-speed steel with powder metallurgy) and features a TiCN coating and S‑NC spiral point geometry designed for efficient chip evacuation during serial and through-hole tapping. Intended for cutting internal metric M12 threads in industrial machining and maintenance operations, the tool combines wear resistance with dimensional accuracy for repeatable thread production.

Advantages

The HSSE-PM substrate delivers high hardness and toughness for extended tool life under cyclic loads. TiCN coating reduces friction and increases wear resistance, improving performance on a wide range of steels and alloyed materials. The R45 chamfer provides an optimized lead-in that eases thread engagement, while the 6H tolerance ensures compatibility with standard metric mating parts. Spiral point S‑NC geometry promotes forward chip flow and reduces the risk of chip congestion in through holes and long serial runs.

Suitable for

• Creating internal M12 metric threads in through-holes
• High-volume or serial tapping operations in production environments
• Maintenance and repair tasks on machinery where standardized metric threads are required
• Machining of steel and alloy materials where improved wear resistance is beneficial

Key specifications

• Thread size: M12 (metric)
• Standard: DIN-376C
• Chamfer: R45
• Tolerance class: 6H
• Material: HSSE-PM (powder-metallurgy high-speed steel)
• Coating: TiCN (titanium carbonitride)
• Geometry: S‑NC spiral point (for forward chip evacuation)

How to use

Select a correctly sized pilot hole according to DIN-376C recommendations and secure the workpiece to prevent movement during tapping. Use appropriate cutting fluid for the material being machined to extend tool life and improve surface finish. Align the tap with the hole axis and apply steady rotational feed; for through-holes, the spiral point S‑NC design will evacuate chips forward. Retract the tap periodically on long runs to clear chips if required and inspect threads for dimensional conformity after machining.

Usage recommendations

For best results, match cutting speed and feed to the workpiece material, maintain correct coolant application, and replace the tap when signs of wear or chipping appear to preserve thread quality and dimensional accuracy.
