Round knives for the cardboard industry, plus circular slitting knives for film and foil converters, paper mills and tissue lines. Each blade is ground from tungsten carbide, HSS M2, D2 or SKD11 to your OD, ID and thickness, with an edge geometry matched to the material you run — a shallow bevel for corrugated board, a keener angle for thin film. Circular slitting blade standard sizes ship from stock; custom diameters, keyways and coating options are made to drawing. Every batch is inspected for runout before packing.

Tell us your line speed, strip thickness and knife clearance and our engineers will recommend the grade and edge geometry that gives the lowest cost per tonne slit — including tungsten carbide slitter blades for abrasive webs.
