Sandvik’s partnership with National Steel Rule of America has developed a broad range of rules that have been performance evaluated against the criteria of pressure required to cut a given material, penetration into blanket, appearance of substrate edge after diecutting, wear of rules and bendability.

Snadvik’s international rotary services centres, using National’s Accu Curve technology, provide an even faster service for pre-curved rule for all cylinder sizes. The rules are stress relieved for improved performance.

National Euro-Cut

Jointly developed by Snadvik and National Steel Rule, Euro-Cut™ is the first rotary cutting rule specifically designed to meet the needs of diamakers and diecutters.

Euro-Cut is a shaved edge, symmetrically ground, centre bevel rule that incorporates Nat-Ex™ hardening technology. The combination of the Nat-Ex™ edge on a 345 HV body provides, superior bendability along with extended die life.

Euro-Cut’s™ unique 8 and 10 tooth designs reduce cutting pressure on heavy and wet board which improves stripping and extends anvil life. The shavededge cuts cleanly through all grades of board which reduces both edge crush and paper dust.

Euro Cut’s™ works equally well around or across the cylinder. The exceptional cutability of their rule even allows you to use the same height cutting rule in both directions. Euro-Cut™ is available in a harder version (500 HV) for tough lead and trail edge applications.

National Standard 8, 10 and 12 Tooth

National standard rotary cutting rules have a smooth shaved bevel and are symmetrically ground to exacting standards. They are available in all rotary heights and can be edge hardened for even longer life.

National 8 Tooth has an aggressive tooth configuration and is used typically for long horizontal cuts. 8 Tooth is an excellent choice when diecutting heavier board grades such as double wall.

10 Tooth is National’s most versatile cutting rule. This radius gullet rule provides an excellent combination of cutability and bendability across a wide range of board grades. National 10 Tooth is the world’s most widely used rotary cutting rule.

National 12 tooth cutting rule is the ‘original’ high performance rule.

National Klean Kut

National Klean Kut is available in 8, 10 and 13 tooth version. Standard 8 tooth klean Kut is Produced from a harder rule for better wear resistance (13 tooth is edge hardened, 8 and 10 tooth area available edge hardened). Klean Kut is an excellent choice for tough lead edge applications.

Klean Kut is a rule designed to cut with minimum pressure and penetration on both medium and heavy board. It has excellent bendability, reduces edge crush and improves stripping when the serrations are placed towards the waste.

Klean Kut is a multi-purpose that works extremely well on fibrous material, plastics and corrugated, leaving a smooth edge on the substrate.

National Arrowhead

Standard 8 tooth Arrowhead combines the benefit of a longer shave bevel for improved release with an induction hardeded edge for longer life. It reduces edge crush and is excellent for medium to heavy boards.

10 tooth Arrowhead has all the benefits of standard Arrowhead plus the fine tooth pattern gives with standard 8 tooth Arrowhead across the drum.

National Scalloped

Scalloped rule has an extremely durable tooth that works well under the most demanding of applications. The 8 tooth centre bevel leaves a clean scalloped edge on solid fibre substrates, rubber and certain plastics and a straight edge on corrugated material.

Subject to applications it is available in both harder steels and edge hardened for longer life without sacrificing bendability.

Curved Diameters available 203.2mm (8.00") and above.
