Thread Tap FANAR M6 DIN 371B (6H) HSSE-PM TiCN S-NC

FANAR thread tap M6 DIN 371B (6H) HSSE-PM TiCN S-NC is a precision cutting tool intended for producing internal ISO metric threads to M6 size. Manufactured from high-speed steel with powder metallurgy (HSSE-PM) and finished with a titanium carbonitride (TiCN) coating, this tap follows DIN 371B geometry for general-purpose tapping in through and blind holes depending on the selected DIN 371B type. The design balances cutting performance and wear resistance for workshop and light machine-shop applications.

Advantages

The HSSE-PM material provides consistent hardness and toughness, reducing the risk of premature breakage while maintaining sharp cutting edges. The TiCN coating increases surface hardness and improves lubricity, which helps extend tool life and reduce built-up edge when machining steels and harder alloys. The DIN 371B geometry ensures reliable chip formation and evacuation in conventional tapping operations.

Suitable for

• Cutting internal ISO metric M6 threads in through holes
• Cutting internal ISO metric M6 threads in blind holes (select appropriate DIN 371B type)
• Workshop hand tapping and machine tapping fixtures
• Machining medium to high-strength steels and harder alloyed materials

Key specifications

• Thread profile: ISO metric, M6
• Tolerance class: 6H
• Material: high-speed steel produced by powder metallurgy (HSSE-PM)
• Surface treatment: titanium carbonitride (TiCN) coating
• DIN geometry: 371B (suitable for through and blind hole variants)
• Application type: straight flute spiral-point or hand/machine-compatible geometry for general-purpose tapping

How to use

Select the correct DIN 371B variant for through or blind hole tapping and ensure the workpiece has the appropriate clearance and chamfer for M6 thread entry. Use an appropriate cutting fluid or coolant for steel and harder alloys to reduce heat and improve chip evacuation. For machine tapping, set spindle speed according to material recommendations and use proper alignment to avoid side loads. For hand tapping, use a suitable tap wrench and apply steady, controlled torque while periodically reversing the tap to break chips if needed.

Usage recommendations

To maximize tool life and thread quality, pre-drill with the recommended core drill diameter for M6, maintain correct tap alignment, and use cutting fluid when tapping steels and harder alloys. Inspect the tap regularly for wear on the coating and cutting edges; replace when thread quality degrades or chipping occurs.
