Tap FANAR GWINTOWNIK M 7 DIN-371B (6H) HSSE TiN 800X for threading M7

FANAR GWINTOWNIK M 7 DIN-371B (6H) HSSE TiN 800X for threading M7 is a machine tap intended for cutting internal metric threads M7. Manufactured to DIN-371B geometry and 6H tolerance class, the tap is made from high-speed steel with cobalt (HSSE) and has a titanium nitride (TiN) coating for increased surface hardness and wear resistance. The tool is suitable for use in production environments and workshops where consistent, precise M7 threads are required in a variety of materials compatible with HSSE tooling.

Advantages

The HSSE substrate provides improved hot hardness and toughness compared with standard high-speed steels, while the TiN coating reduces friction and extends tool life under cyclic cutting conditions. Conformance to DIN-371B geometry ensures defined thread profile and flute form for reliable chip evacuation in through and blind holes. The tool's 6H tolerance supports accuracy and interchangeability of fastened assemblies.

Suitable for

• Cutting internal metric threads M7 in production and maintenance
• Threading in steel alloys and general-purpose metals compatible with HSSE tools
• Through-holes and blind holes where DIN-371B geometry is required
• Workshop use on tapping machines, drill presses, and machining centers

Key specifications

• Thread size: M7 metric internal thread
• Thread form and geometry: DIN-371B
• Tolerance class: 6H
• Material: high-speed steel with cobalt (HSSE)
• Coating: titanium nitride (TiN)
• Design purpose: machine tap for production and workshop threading

How to use

Secure the tap in an appropriate holder or machine spindle, ensuring concentricity with the hole axis. Use the recommended drilling size for a pilot hole suitable for M7 threading according to standard tap drill charts. Apply appropriate cutting fluid for the work material to improve lubrication and chip evacuation. Run the tap at speeds and feed rates compatible with the material and machine tool, using intermittent reversal or peck tapping for deep or blind holes to prevent chip packing. After threading, back the tap out carefully to avoid damaging the thread.

Usage recommendations

For best results, match cutting parameters to the specific material being machined and replace the tap when wear or coating degradation affects thread quality. Store the tap in a dry, protected environment to preserve the TiN coating and geometry.
