Why choose it

Made from high-speed steel, this tap offers a good balance of hardness and toughness for general-purpose threading. The DIN 352 standard ensures compatibility with common tap wrenches and holders. Its bright finish reduces friction during cutting, helping to produce smooth threads in steels and non-ferrous metals.

Ideal use cases

• Hand tapping of through holes and blind holes in maintenance and repair work
• Creating threads in general-purpose steels and non-ferrous metals
• Finishing operations where thread accuracy and surface finish are critical

Good to know

As a finishing tap, it is intended for the final cut after a taper or plug tap has roughed out the thread. Use appropriate cutting fluid to extend tool life and improve thread quality. The right-hand cutting direction suits standard clockwise tapping.
