Why choose it

Precision-ground from HSS for durability and clean thread cutting, this tap delivers consistent results in manual threading operations. The DIN 352 geometry ensures correct thread form and pitch, while the bright finish reduces friction and eases chip evacuation.

Ideal use cases

• Creating internal threads in steel plates and castings
• Repairing or restoring damaged threads in maintenance workshops
• Threading non-ferrous metals such as aluminium and brass
• Manual threading in toolrooms and production environments

Good to know

The tap is designed for right-hand cutting and requires a suitable tap wrench with a 12.0 mm square drive. It is intended for through-hole or blind-hole threading where a finishing tap is appropriate. Always use appropriate cutting fluid for the workpiece material to extend tool life.
