Product Overview
Designed for heavy-duty industrial slitting operations, the Dekeer Longitudinal Shear Circular Blade is a professional cutting tool engineered to deliver exceptional performance in metal sheet processing. Whether you’re slitting copper foil, aluminum foil, or silicon steel sheets, this circular slitter blade combines premium materials, ultra-fine precision, and durable construction to meet the demands of rolling slitting lines, rewinding machines, and other industrial cutting equipment. Backed by Dekeer’s decades of knife-making expertise, it’s the reliable choice for metal processing, building materials, and packaging industries worldwide.
Core Advantages: Why Dekeer’s Circular Slitter Blade Stands Out
1. Premium Materials for Maximum Durability
Crafted from industry-leading high-performance steels, the blade is available in four material options to match your specific cutting needs:
D2: High-carbon, high-chromium tool steel with excellent wear resistance, ideal for general metal slitting.
LD: Low-alloy cold-work die steel, balancing toughness and hardness for medium-duty applications.
LD+Ni: LD steel enhanced with nickel, boosting corrosion resistance and impact strength—perfect for humid or harsh environments.
SKD11: Japanese-standard cold-work die steel, offering superior edge retention and durability for high-volume, repetitive slitting.
2. Ultra-Precision Cutting for Consistent Results
Precision is non-negotiable in industrial slitting—and this blade delivers:
Tolerance Control: For blades with an outer diameter ≤350mm, parallelism, flatness, and thickness tolerance reach an impressive 0.002mm. This ensures uniform cuts, minimal material waste, and seamless compatibility with high-speed slitting lines.
Surface Finish Options: Customizable mirror-like or matte surfaces to reduce friction, prevent material adhesion, and extend blade lifespan.
High Cutting Efficiency: Engineered for smooth, burr-free slitting, even with thin or tough metal sheets (e.g., copper foil, silicon steel), improving production speed and product quality.
3. Flexible Customization for Unique Needs
No two industrial setups are the same—we tailor the blade to your requirements:
Size Customization: Fully based on your customer’s drawing (no standard size limitations). We also offer popular pre-made sizes for quick ordering (see Partial Sizes section below).
Branding Options: Add your company’s name plate or logo to the blade (Minimum Order Quantity: 20 pieces), enhancing brand recognition in your production line.
Line Compatibility: Designed to fit German and Japanese production lines—trusted by major material factories for its seamless integration and reliable performance.
4. Strict Quality Assurance & Industry Expertise
Dekeer’s commitment to quality ensures every blade meets the highest standards:
100% Pass Rate: Every blade undergoes rigorous inspection before shipment, supported by advanced testing equipment and a 12-step quality control process.
ISO 9001:2015 Certification: Our manufacturing process complies with international quality management standards, guaranteeing consistent performance.
Decades of Experience: With two dedicated factories (Doctor Blade Factory & Circular Blade Factory) and expertise in custom cutting tools, we understand the unique challenges of industrial slitting.
