Hand Tap FANAR DIN-376C R40 HSSE TiN 800X M12

FANAR hand tap DIN-376C R40 HSSE TiN 800X M12 is a manual thread-cutting tool engineered to form or restore internal metric threads in metallic materials. Conforming to DIN-376C form, this M12 tap is manufactured from high-speed steel with cobalt (HSSE) and finished with a titanium nitride (TiN) coating to increase surface hardness and reduce wear during repeated use in workshop and maintenance environments.

Advantages

The HSSE base material provides improved toughness and heat resistance compared with standard high-speed steel, while the TiN coating reduces friction and extends service life by protecting the cutting edges. The DIN-376C geometry ensures consistent thread form and compatibility with standard thread tolerances. The tool's specification (800X) and robust construction make it suitable for hand operation and controlled manual tapping, offering predictable chip formation and thread quality.

Suitable for

• Cutting new internal M12 metric threads in steel and non-ferrous metals
• Repairing damaged or worn M12 threads in maintenance and service work
• Workshop manual tapping where DIN-376C form is required
• Low- to medium-production manual operations with attention to proper lubrication

Key specifications

• Thread size: M12 (metric)
• Standard form: DIN-376C
• Material: HSSE (high-speed steel with cobalt)
• Surface finish: TiN (titanium nitride) coating for reduced wear
• Tool type: hand/plug tap for internal threading
• Specification: 800X series

How to use

Secure the workpiece rigidly and select an appropriate drill size for the M12 tap. Use correct alignment to avoid angled entry and start the tap slowly by hand in the pre-drilled hole. Apply suitable cutting lubricant to reduce friction and improve chip evacuation. Advance the tap with steady rotational motion and periodically reverse it slightly to break chips. Complete threading by withdrawing the tap carefully once the required depth is reached, then clean the thread and inspect for conformity with the required tolerances.

Usage recommendations

Use cutting oil or appropriate lubricant when tapping steel or alloy materials to prolong tool life and improve surface finish. Avoid excessive axial force and ensure proper alignment to prevent tap breakage. For hardened or abrasive materials, evaluate machining parameters and consider using specialized taps if material hardness exceeds HSSE capability.
