Thread Tap FANAR M6 DIN 371C (6H) HSS-E TiN 800 mm

Thread Tap FANAR M6 DIN 371C (6H) HSS-E TiN 800 mm is a hand and machine tap designed for cutting M6 metric threads to DIN 371C standard with 6H tolerance. Constructed from high-speed steel with cobalt alloy (HSS-E) and finished with a titanium nitride (TiN) coating, this long tap offers improved wear resistance and surface hardness. With an overall length of 800 mm it is intended for applications that require extended reach or deep-thread tapping in workshop and industrial environments.

Advantages

The HSS-E material provides increased red hardness and durability compared with conventional high-speed steel, while the TiN coating reduces friction and extends tool life. The DIN 371C geometry ensures consistent thread profile and chip evacuation for through and blind holes. The long 800 mm length enables access to deep bores and hard-to-reach positions without additional extensions.

Suitable for

• Cutting M6 internal metric threads in steels and similar materials
• Deep-hole or extended-reach tapping operations
• Hand tapping and machine tapping where DIN 371C profile is required
• Workshop, maintenance and industrial production environments

Key specifications

• Thread size: M6
• Standard and tolerance: DIN 371C, 6H tolerance
• Material: high-speed steel with cobalt (HSS-E)
• Coating: titanium nitride (TiN)
• Overall length: 800 mm
• Application type: hand and machine tap
• Suitable hole types: through and blind holes

How to use

Select the correct M6 pilot hole diameter according to DIN tapping recommendations for the material being machined. Secure the workpiece and ensure the tap is aligned perpendicular to the hole to avoid thread damage. For machine tapping use appropriate speed and feed settings for HSS-E tools; apply suitable cutting fluid to prolong tool life and improve chip evacuation. For hand tapping, turn the tap in progressively and back off periodically to break chips. After tapping, inspect the thread for correct form and fit using a gauge or mating fastener.

Usage recommendations

Use cutting fluid appropriate for steel and similar alloys, maintain correct alignment during tapping, and avoid excessive feed or speed to reduce wear. For repetitive or high-volume operations, monitor tap condition and replace when wear or coating degradation affects thread quality.
