High-Precision Circular Paper Cutting Blades: Clean Edges, Zero Dust
In the fast-paced paper converting and packaging industry, your circular cutting blades directly affect: Roll finish qualityProduction stabilityFinal product consistency
Dull or poorly made blades don’t cut cleanly. They tear paper, create dust, damage equipment, cause web breaks, and hurt print/packaging quality. Our slitter knives are built for high-speed, precise cutting of all paper types—from thin tissue to thick cardboard. They fix common cutting problems, last longer, and reduce downtime.
Why Our Slitter Knives Are Better Than Standard Blades
Mirror-Finish Lapping
Our blades go through special mirror polishing and lapping. Benefits include: Less frictionNo paper fibers sticking to the bladeDust-free cutting, even at max speed
Advanced Material: HSS (High-Speed Steel)
We offer high-performance HSS for different needs. It’s a high-performance alloy with tungsten, molybdenum, chromium, and vanadium, made for tough cutting conditions. Cr12: Durable, low-cost, good for daily medium-load cutting HSS (High-Speed Steel): Tough, heat-resistant, perfect for high-speed, high-demand lines
Strict Dimensional Control
Our slitter knives have tight precision: Thickness tolerance: ±0.002mmExcellent concentricityStable cutting paths, no web breaksConsistent slit widths
Core Uses & Applications
Our circular slitter knives work for many paper processing tasks: Paper & Packaging: Slit kraft paper, coated paper, newsprint, cardboard, labels, and tissue Converting & Finishing: Precise width cutting for printing, laminating, bag-making, and rewinding High-Speed Lines: Runs steadily at 300–800 m/min (needs sharpness, durability, low vibration) Specialty Uses: Thermal paper, adhesive labels, multi-layer laminated paper, and high-value printed materials
Key benefits: Sharp edge, clean cuts (no burrs), long life, less downtime, consistent precision.
Material 1: Cr12 (Alloy Tool Steel)
Cr12 is a high-carbon, high-chromium steel. It’s the low-cost, reliable choice for paper slitting.
Key Features
Hardness: HRC 58–62 (after heat treatment)
Durable: 3–5 times longer life than carbon steel (thanks to chromium carbides)
Stable: Little distortion during heat treatment (good for precision blades)
Tough enough: Works for smooth, low-impact cutting
Low cost: Cheaper than HSS or tungsten carbide
Best For
Medium-to-thick paper, cardboard, and kraft paper
Abrasive materials (coated, laminated paper)
Long production runs (prioritize durability)
Standard precision cutting (tolerance ±0.01–0.02 mm)
Material 2: High-Speed Steel (HSS / M2 / W6Mo5Cr4V2 / SKH51)
HSS is a high-performance alloy with tungsten, molybdenum, chromium, and vanadium. It’s made for tough cutting conditions.
Key Features
Hardness: HRC 60–68 (higher than Cr12)
Heat-resistant: Keeps hardness at high temps (about 500°C) from fast cutting friction
Very tough: Resists chipping (better than Cr12), even on thick/uneven paper
Sharp edge: Can be honed to a fine edge for cleaner, less dusty cuts
Best For
High-speed cutting lines (where heat builds up)
Thick, stiff, or tough cardboard
Sensitive materials (thin tissue, release paper, high-grade labels)
Tasks needing maximum toughness, edge stability, and long life
Cr12 vs. HSS: Key Differences
Hardness: Cr12 (HRC 58–62) | HSS (HRC 60–68, slightly higher)
Durability: Cr12 (excellent, high carbide) | HSS (very good, heat-resistant)
Toughness: Cr12 (good for low-impact) | HSS (excellent, resists chipping)
Heat resistance: Cr12 (moderate) | HSS (outstanding, stable at high speeds)
Edge sharpness: Cr12 (good) | HSS (superior, cleaner cuts)
Cost: Cr12 (cheaper, economical) | HSS (premium, higher performance)
Best uses: Cr12 (cardboard, coated paper, abrasive materials) | HSS (high-speed lines, thin/sensitive paper, labels, high-value printed materials)
Design & Precision Features
Our slitter knives have practical, reliable design with strict precision:
Structure: Solid circular disc with smooth flat edges (optimized for paper)
Precision: OD, ID, thickness and runout controlled tightly
Edge: Single or double bevel, sharp and precise
Heat treatment: Ensures stability, hardness and toughness
Surface: Mirror-polished to reduce friction and fiber adhesion
Selection Guide
Choose the right material based on your production needs:
Choose Cr12 if:
You cut medium-to-thick paper, cardboard or abrasive materials
You want long service life at a low cost
Your production runs at medium speed with stable loads
Choose HSS if:
You operate high-speed cutting lines (with heat buildup)
You need clean, burr-free cuts on thin or sensitive paper
You want maximum toughness and edge stability
You slit high-value materials (labels, thermal paper, printed paper)
Maximize Your Production Efficiency
Our slitter knives are built to last longer and cut cleaner. This means:
Whether you choose Cr12 or HSS, our blades keep your paper converting, packaging and printing lines running smoothly.
We manufacture high-performance Circular Paper Cutting Blades (Material: HSS, Tungsten Carbide, 9CrSi, Cr12MoV) designed for precise slitting, trimming, and rewinding. Our rotary knives feature ultra-fine finishes and high wear resistance, optimized for paper mills, packaging plants, and printing industries. Available in top and bottom knife configurations for dust-free cutting.
