Tap FANAR GWINTOWNIK M2 DIN-371B (6H) HSSE-PM INOX HARDLUBE

FANAR GWINTOWNIK M2 DIN-371B (6H) HSSE-PM INOX HARDLUBE is a machine tap designed to cut internal metric threads with a 2 mm nominal diameter according to DIN 371B standard. Manufactured from HSSE-PM (high-speed steel with powder metallurgy) and finished with an INOX HARDLUBE coating, the tool is intended for reliable threading of stainless steel and a range of other metallic materials. Supplied as a single-item tap, it is suitable for use in machining centres, tapping machines and compatible handholders where precise M2 internal threads are required.

Advantages

The HSSE-PM substrate provides high hardness and toughness for extended tool life under mechanical loads. The INOX HARDLUBE coating improves wear resistance and reduces friction when cutting stainless steel and other difficult-to-machine alloys. Conforming to the DIN 371B profile ensures consistent thread geometry and dimensional accuracy within the 6H tolerance class. The tap’s design supports machine tapping operations as well as use with appropriate handholders for repair or small-batch work.

Suitable for

• Cutting M2 internal metric threads in stainless steel
• Threading in non-ferrous metals and general-purpose steel
• Machine tapping in CNC or dedicated tapping machines
• Repairing or rethreading existing holes with M2 threads

Key specifications

• Thread size: M2 metric (nominal 2 mm)
• Thread form: DIN 371B straight flute machine tap
• Tolerance class: 6H internal thread
• Material: HSSE-PM (powder metallurgy high-speed steel)
• Surface finish: INOX HARDLUBE coating for improved wear resistance
• Supply: single-item (individual tap)

How to use

Select the correct pilot drill and prepare the hole to the recommended drill size for M2 threads. Mount the tap in a suitable tapping machine or handholder, ensuring axial alignment and secure clamping. Use appropriate cutting speeds and feed for HSSE-PM tools and the workpiece material; apply suitable cutting fluid when machining stainless steel or other sticky alloys. Perform threading in steady, controlled feeds, clearing chips frequently to avoid tool breakage; for hand use, employ the correct torque and back-off technique to evacuate chips.

Usage recommendations

Use drills and tapping parameters recommended for M2 DIN 371B threads and adjust spindle speed and lubrication according to the workpiece material. Inspect thread quality after cutting and replace the tap if wear or chipping is detected to maintain thread accuracy.
