Today, many diemakers prefer using one rule that can be effectively used in both directions on a wide range of board grades. National’s 10Tooth rule fulfills that preference and is the most popular, most commonly used rotary rule in the world today.

National 10 Tooth is engineered to cut with minimal pressure and penetration on boards ranging from 175 test C-Flute through 600 test Double Wall. The combination of the shaved bevel and symmetrically ground radius tooth provide optimal performance, both around and across the cylinder.

The unique design of the tooth provides exceptional wear resistance, while maintaining superior bendability. Like all National rotary rules, 10 Tooth is available in both standard and edge hardened varieties.
