Round Slitting Knives in D2, HSS or SUS420 — Ground to a ±0.02 mm Mirror Finish
The payoff is a clean, stable, burr-free slit from the first metre to the last, with a working life up to three times longer than an ordinary ground blade. Dimensional accuracy is held to +/-0.02 mm, so the knife stays concentric and will not flutter even at full production speed.
Key Advantages
The Right Steel for Your Web HSS for high-speed paper, D2 for abrasive film and foil, SUS420 wherever moisture or corrosion is a factor — each grade vacuum hardened to its optimal HRC range (52-62) for maximum edge life. | Polished Double Bevel Edge A precision-ground, mirror-finished bevel cuts friction and heat, leaving clean slit edges on even the most sensitive films and reducing machine vibration. |
±0.02 mm Dimensional Control Every blade is checked to a tight +/-0.02 mm tolerance. High concentricity keeps the knife running true and stops blade jump during long, fast production runs. | Inspection Proof with Every Order Nothing ships on trust alone: you receive an outgoing video inspection plus a formal machinery test report, so quality is verifiable before the blades reach your line. |
One Knife, Many Materials From thin paper rolls and packaging board to aluminum foil, pearl film and non-woven textiles — the blade geometry is optimised for stable slitting across the whole range. | Built-to-Drawing Custom Service Our engineers produce custom diameters, bores, thicknesses, materials and laser-marked logos from your drawings or samples, matched precisely to your slitter rewinder. |
