Tap FANAR NARZYNKA M8 DIN-22568 (6g) HSS 800 SPN

FANAR NARZYNKA M8 DIN-22568 (6g) HSS 800 SPN is a machine tap designed for producing M8 metric internal threads to DIN 22568 tolerance class 6g. Manufactured from HSS 800 tool steel, this tap is intended for precision thread cutting in compatible ferrous and some non-ferrous materials. It is suitable for use in tapping machines and hand holders where a straight-profile machine tap is required for repeatable, accurate threading operations.

Advantages

The HSS 800 material offers a balance of hardness and toughness for reliable wear resistance and longer cutting life under standard machining conditions. Conforming to DIN 22568 ensures dimensional and tolerance consistency for interchangeability and correct fit with M8 bolts and mating parts. The 6g tolerance provides a common commercial fit suitable for general engineering applications. As a machine tap, it is optimized for use with power-driven tapping equipment, promoting consistent chip evacuation and uniform thread form when used with appropriate speeds and lubricants.

Suitable for

• Producing M8 internal metric threads in steel and similar metals
• Series production on tapping machines in metalworking shops
• Maintenance and repair operations requiring standard M8 threads
• Use with machine holders and appropriate tapping adapters

When it may not be suitable

This tap is not intended for forming threads in ductile materials where a forming (roll) tap is required; it is a cutting tap designed for HSS applications. It may not be optimal for high-speed or high-temperature titanium or hardened steel machining without suitable coatings, tool materials, or cutting parameters; in such cases carbide or coated taps and modified machining settings should be considered.

Key specifications

• Thread size: M8 (metric)
• Standard: DIN 22568
• Tolerance class: 6g
• Material: high-speed steel (HSS 800)
• Type: machine tap for cutting internal threads

How to use

Select the correct pilot drill size for M8 threads and secure the workpiece. Mount the tap in a machine holder or suitable hand holder that provides axial alignment and torque control. Use appropriate cutting fluid for the workpiece material to reduce friction and aid chip evacuation. Operate the tapping machine at recommended spindle speeds and feed rates for HSS material, periodically reversing or withdrawing the tap to break and clear chips if necessary. After cutting, inspect thread form and fit with a gauge or mating fastener.

What to consider before purchase

• Verify material compatibility (HSS 800) with your workpiece metal
• Confirm that DIN 22568 and tolerance 6g meet assembly and interchangeability requirements
• Ensure you have the correct drill size, holder, and tapping machine settings
• Consider alternative tap types (forming, coated, or carbide) if working materials are unusual or highly abrasive

Usage recommendations

For best results, use recommended pilot drill sizes and cutting fluids, maintain correct spindle speed for HSS tools, and inspect threads after production. Replace taps when wear affects thread quality to maintain consistent tolerance and fit.
