Product Description
Tungsten Carbide (TCT) Rotary Slitter Blades
Premium carbide rotary slitter blades engineered for highly abrasive materials with HRA 80-94 hardness, sharp edge retention, and extended service life. Ideal for copper foil, aluminum, and composite material slitting applications.
Experience unmatched longevity with our Tungsten Carbide (TCT) Rotary Slitter Blades.
Designed for the most abrasive and demanding applications, these solid carbide or tipped blades offer hardness levels far exceeding traditional steel, ensuring consistent performance over extended periods.
Key Features & Benefits
  • Extreme Hardness: HRA 80-94 hardness ratings (approx. HRC 68-75) provide superior wear resistance against highly abrasive materials like fiberglass, carbon fiber, and coated metals
  • Ultra-Sharp Edge Retention: Maintains razor-sharp edges significantly longer than steel blades, reducing change frequency and improving production line efficiency
  • Precision Manufacturing: Ground to ultra-fine tolerances (±0.001mm) with mirror-polished surfaces (Ra0.2) for clean, burr-free cuts on delicate foils and thin strips
  • Versatile Material Processing: Ideal for slitting copper foil, aluminum foil, lithium battery electrodes, PCB substrates, and composite materials
  • Coating Options: Available with advanced coatings (TiCN, CrN) to enhance lubricity and prevent material buildup
