Tap FANAR NARZYNKA M 3 DIN-22568 HSS 800 – metric M3, 6 threads-per-inch marking (6e)

FANAR NARZYNKA M 3 DIN-22568 HSS 800 is a high-speed steel metric M3 tap designed for cutting internal threads to DIN-22568 standards. Marked 6e for tolerance class, this HSS 800 tool is intended for use in manual tapping or machine tapping operations where precise M3 threads are required. It is suitable for common metalworking materials and workshop environments where a standard M3 thread form is needed.

Advantages

The HSS 800 material provides a balance of toughness and wear resistance suitable for general-purpose tapping. Conformance to DIN-22568 and the 6e tolerance marking ensures consistent thread geometry and interchangeability with corresponding M3 fasteners. The design supports both hand and machine use, offering flexibility for repair, prototyping, and production tasks where standard metric M3 threads are specified.

Suitable for

• Cutting internal metric M3 threads in steel, stainless steel, aluminum alloys, and other common workshop metals (subject to correct speeds and lubrication)
• Hand tapping operations using a tap wrench or T-handle
• Machine tapping on drill presses, tapping machines, or milling machines with appropriate tap holders
• Repairing or reconditioning existing M3 threaded holes

When it may not be suitable

This tap is not intended for materials outside the recommended capabilities of general-purpose HSS, such as hardened steels above the HSS cutting range or highly abrasive non-metallic materials. For high-volume production in hard materials or interrupted cuts, a coated or carbide tap specifically rated for those conditions may be more appropriate. Also, specialized thread forms or non-standard tolerances require different tooling.

Key specifications

• Thread size: metric M3
• Tolerance class: 6e (tolerance fit marking)
• Standard: DIN-22568
• Material: high-speed steel (HSS 800)
• Intended use: internal thread cutting, hand and machine tapping

How to use

Drill the appropriate pilot hole for an M3 thread according to standard drill charts, secure the workpiece, and ensure alignment with the axis of the hole. Use cutting fluid suitable for the workpiece material to reduce friction and extend tool life. For hand tapping, start the tap straight and apply steady clockwise rotation, reversing periodically to break and clear chips. For machine tapping, select appropriate spindle speed, feed, and torque settings, and use a rigid holder or floating tap holder as required to prevent breakage.

What to consider before purchase

• Confirm the workpiece material and whether HSS 800 is suitable for that material and hardness
• Verify required thread tolerance and fit; 6e is a standard tolerance class for M3 threads
• Ensure correct pilot drill size and availability of appropriate tap holders or wrenches for hand or machine use

Usage recommendations

Use appropriate cutting fluid, maintain correct pilot hole size, and avoid excessive side loads. For blind holes, withdraw the tap frequently to clear chips. Replace the tap when wear or damage affects thread quality to maintain consistent M3 thread performance.
