Why choose it

The DIN 2181 standard guarantees dimensional accuracy and interchangeability, while the ground flutes and 60° flank angle provide smooth chip evacuation and reduced cutting forces. The 6H tolerance class ensures a precise fit for metric fine threads, making it suitable for high-quality threaded connections.

Ideal use cases

• Cutting M9x1.00 metric fine threads in metal workpieces
• Repairing or restoring damaged threads in maintenance tasks
• Producing threads in blind holes where a bottoming tap is not required
• Manual threading operations in workshops and manufacturing

Good to know

The square drive shank fits standard tap wrenches for secure torque transmission. The bright finish reduces friction and improves chip flow. For best results, use a suitable cutting fluid and pre-drill with an 8.0 mm core hole.
