Why choose it

The tap is made from high-speed steel, offering good wear resistance and durability for threading operations. Its DIN 2181 compliance ensures compatibility with standard tap holders and machine spindles, and the 6H tolerance class produces threads that meet common engineering specifications.

Ideal use cases

• Creating metric fine threads in through holes
• Production machining on CNC or manual machines
• Threading steel, cast iron, and similar materials

Good to know

The tap is uncoated, which is typical for general-purpose HSS taps. For best results, use an appropriate cutting fluid and ensure the core hole is drilled to the recommended diameter of 19.0 mm.
