Tap FANAR NARZYNKA M 8x0.75 DIN-22568 (6g) HSS 800

FANAR NARZYNKA M 8x0.75 DIN-22568 (6g) HSS 800 is a machine tap designed to cut internal metric threads with a nominal size of M8 and a pitch of 0.75 mm. Produced from HSS 800 high-speed steel and manufactured to the DIN-22568 dimensional and tolerance standard, this tap provides consistent thread geometry with a 6g tolerance grade suitable for a wide range of metalworking applications. The tool is intended for use in production, maintenance, and repair operations where accurate internal threads are required.

Advantages

The HSS 800 material offers good wear resistance and toughness for machining common ferrous and some non-ferrous materials. Compliance with DIN-22568 ensures interchangeability of thread profile and pitch, while the 6g tolerance provides a balance between fit precision and manufacturability. The tap’s geometry and heat-treated high-speed steel construction deliver stable cutting performance and a predictable tool life when used with appropriate speeds, feeds and lubricants.

Suitable for

• Cutting M8 x 0.75 internal threads in steel components
• Maintenance and repair of machinery with metric fine threads
• Batch or single-piece production where DIN-standard threads are required
• Tool rooms and workshops performing threaded hole preparation

Key specifications

• Thread size: M8
• Pitch: 0.75 mm
• Standard: DIN-22568
• Tolerance class: 6g
• Material: High-speed steel (HSS 800)
• Type: Machine tap for internal threads

How to use

Secure the workpiece and ensure the hole is prepared to the correct drill size for an M8 x 0.75 thread according to standard drilling charts. Mount the tap in an appropriate collet, tap holder or machine spindle designed for hand or machine tapping. Apply a suitable cutting fluid or lubricant for the workpiece material before engaging the tap. Use controlled feed and rotation; for machine tapping follow the machine manufacturer’s recommended speeds and feeds. Reverse the tap periodically to break chips and clear the thread flutes. After cutting, withdraw the tap carefully, clean the threaded hole and inspect the thread for fit and dimensional accuracy.

Usage recommendations

For best results, match drill size and cutting parameters to the workpiece material, use appropriate tapping lubricant, and monitor tap wear. When tapping harder alloys or stainless steels, reduce speed and increase lubrication. Replace the tool when surface finish or dimensional accuracy degrades to maintain compliance with the DIN-22568 tolerance.
