Why choose it

The HSS construction provides good wear resistance and cutting performance for manual threading operations. The bottoming form allows threads to be cut almost to the bottom of blind holes, making it suitable for final threading after taper or plug taps. The bright finish reduces friction and helps clear chips.

Ideal use cases

• Cutting internal metric fine threads in blind holes
• Maintenance and repair work on machinery and equipment
• Threading in unalloyed and alloyed steels up to 800 N/mm², cast iron, and non-ferrous metals
• Manual threading with a tap wrench

Good to know

The tap conforms to DIN 352 for dimensions and tolerances. It is intended for hand use and should be used with a suitable tap wrench. For best results, use cutting oil and clear chips frequently.
