Tap Topex M12 tungsten DIN 352 — M12 thread cutting tap

Tap Topex M12 tungsten DIN 352 — M12 thread cutting tap is a precision cutting tool intended for producing internal metric threads of size M12. Manufactured by Topex to the DIN 352 standard from tungsten material, this tap is suitable for hand or machine use in metalworking environments. It is intended for creating clean, accurate threads in a range of machinable materials where a robust cutting edge and consistent thread form are required.

Advantages

This M12 tap combines the hardness and wear resistance of tungsten with geometry conforming to DIN 352, providing long tool life and repeatable thread quality. The tool is adaptable for both hand-held and machine tapping operations, helping maintain consistent thread dimensions and surface finish. Its construction reduces the need for frequent regrinding or replacement in routine maintenance and manufacturing tasks.

Suitable for

• Repair and maintenance of mechanical assemblies
• Metalworking shops performing internal thread cutting
• Assembly lines requiring on-site thread preparation
• DIY and professional projects involving M12 threaded connections

Key specifications

• Thread size: M12 (metric)
• Material: tungsten
• Standard: DIN 352 thread and flute geometry
• Application mode: hand or machine tapping
• Intended use: cutting internal threads in machinable materials

How to use

Select the correct pilot hole diameter for an M12 internal thread, secure the workpiece, and align the tap perpendicular to the hole axis. For hand tapping, apply steady, even pressure and rotate the tap forward to cut, then back it off periodically to break and clear chips. For machine tapping, set appropriate spindle speed and feed for the material and use suitable lubrication or cutting fluid to improve chip evacuation and extend tool life.

Usage recommendations

Use cutting fluid appropriate to the workpiece material and avoid excessive feed or speed when machine tapping. Inspect the tap regularly for wear or chipping and replace when thread quality degrades to ensure consistent M12 thread production.
