Tap FANAR M14x1 DIN-374C R40 (6H) HSSE TiN for threading

FANAR tap M14x1 manufactured to DIN-374C standard, size R40 with 6H tolerance, made from HSSE and coated with TiN. This tap is intended for cutting internal metric threads M14×1 in metalworking operations. It is suitable for both machine and hand tapping where DIN-374C conformity is required. The HSSE substrate provides toughness for interrupted cuts and alloyed steels, while the titanium nitride (TiN) coating improves wear resistance and reduces friction during cutting.

Advantages

The combination of HSSE material and TiN coating delivers a balance of durability and surface hardness, extending tool life in production and repair environments. The DIN-374C geometry ensures consistent thread form and alignment when used with corresponding drill sizes and guides. A 6H tolerance class provides a commonly accepted fit for general engineering applications, offering predictable assembly performance. The R40 size designation indicates the tap’s nominal hand and machine suitability according to the manufacturer’s tool series.

Suitable for

• Cutting internal metric threads M14×1 in steels and alloy materials
• Machine tapping on lathes, milling machines, and tapping heads
• Hand tapping where DIN-374C taps are required
• Production runs and maintenance/repair operations

How to use

Select the appropriate pilot hole and drill size for M14×1 according to DIN recommendations, secure the workpiece, and ensure correct alignment of the tap with the hole axis. Use suitable cutting fluid to improve chip evacuation and reduce wear; for machine tapping use the recommended spindle speeds and feed rates for HSSE taps in the material being processed. For hand tapping, apply steady axial pressure and reverse periodically to break chips. Inspect threads after tapping for form and fit before assembly.

Usage recommendations

Use with appropriate drill sizes and clamping fixtures, maintain recommended cutting speeds for HSSE tools, and reapply cutting fluid as required. Store the tap in a dry place and inspect cutting edges before use to ensure optimal thread quality and tool life.
