Thread Tap FANAR M12x1.25 DIN 374C R40 (6H) HSSE TiN 800X

FANAR M12x1.25 DIN 374C R40 (6H) HSSE TiN 800X is a precision thread tap for cutting internal metric threads M12×1.25. Manufactured to DIN 374C standard with a tolerance class of 6H and R40 flute/geometry, this tap is made from high-speed steel with cobalt (HSSE) and finished with a titanium nitride (TiN) coating. The combination of HSSE and TiN enhances hardness and wear resistance, making the tool suitable for repeated use in production and maintenance environments for a variety of metallic materials.

Advantages

The HSSE material delivers improved toughness and heat resistance compared with conventional high-speed steel, while the TiN coating reduces friction and extends tool life. Compliance with DIN 374C and the 6H tolerance ensures consistent thread accuracy and interchangeability with standardized fasteners. The R40 geometry supports chip evacuation and reduces the risk of tap breakage during machine or hand tapping operations.

Suitable for

• Cutting internal metric threads M12×1.25 in steel and alloy steels
• Threading in stainless steels and harder materials when using appropriate cutting conditions
• Machine tapping in production runs and CNC operations
• Hand tapping for maintenance, assembly, and repair tasks
• Workshops requiring durable, wear-resistant tapping tools

Key specifications

• Thread size: M12×1.25
• Standard: DIN 374C
• Tolerance class: 6H
• Flute/geometry: R40
• Material: HSSE (high-speed steel with cobalt)
• Coating: TiN (titanium nitride)
• Intended use: internal thread cutting (tapping)

How to use

Select appropriate machine speeds, feeds, and lubrication based on the workpiece material and the HSSE TiN tool characteristics. For machine tapping, ensure proper alignment with the spindle and use recommended tapping cycles or pecking routines to control chip load. For hand tapping, use a tap wrench and apply steady, even torque while reversing periodically to break chips. Regularly inspect the tap for wear or coating damage and replace when thread quality degrades or tool wear is visible.

Usage recommendations

Use cutting fluid suitable for the workpiece material to improve surface finish and extend tool life. For stainless steels and tougher alloys, reduce cutting speed and increase lubrication. Store taps in a dry, protected container to preserve the TiN coating and prevent corrosion.
