Product Name
Leister Tungsten Carbide Circular Blades (102.401, 102.402, 102.405, 167.025, 167.026)
Brief Description
These are high-performance circular blades, precisely engineered from tungsten carbide, primarily designed for use with Leister GROOVER machines. They are essential tools for preparing elastic floor coverings by cutting grooves, facilitating subsequent hot air welding or cold application with sealants. The blades offer exceptional hardness, superior wear resistance, and precision cutting capabilities for demanding industrial applications.
Popular Applications & Uses
- Grooving elastic floor coverings such as PVC-P (vinyl), PE, CV, PUR, linoleum, and rubber to prepare seams for welding or sealing.- Precision cutting in various plastic fabrication processes.- General industrial cutting tasks involving materials like paper, film, and certain non-ferrous metals.
Industries that Commonly Use It
- Flooring Installer or Manufacturer- Construction/ Building Services- Plastic Fabrication- General Manufacturing (for diverse cutting applications)- Distributers & Resellers
Special and Unique Features
- Tungsten carbide-tipped construction ensures superior hardness and wear resistance, significantly extending blade life compared to traditional steel blades.- Maintains a sharp cutting edge for longer periods, even under continuous, high-intensity use.- Features precision-ground edges and specialized geometries that reduce friction and prevent material buildup, resulting in clean, burr-free cuts.- Available in specific profiles, such as trapezium and round, to meet various grooving requirements.- Designed for optimal compatibility and performance with Leister GROOVER machines.- Exhibits high-temperature resistance, maintaining tooth hardness and preventing thermal deformation during high-speed cutting operations.
Key Properties
- Material: Tungsten Carbide, a composite of tungsten and carbon particles typically embedded in a cobalt matrix.- Hardness: Extremely high, generally ranging from HRA88-92, with some grades exceeding HRA90+.- Wear Resistance: Excellent, offering a significantly longer service life (up to 50% or 3-5 times) compared to steel blades.- Cutting Performance: Delivers superior cutting efficiency, precision, and consistent burr-free edges.- Heat Resistance: Maintains stability and sharpness at high cutting temperatures, preventing thermal deformation.- Durability: Engineered for robustness and to maintain optimal sharpness through demanding production cycles.
Surface Compatibility
- Elastic floor coverings: PVC-P (vinyl), PE, CV, PUR, Linoleum, and Rubber.- Various types of plastics.- Paper and film materials.- Non-ferrous metals, including aluminum, copper, and titanium alloys.- Wood, hardwood, veneer board, PCB, and composite materials.
Known backups / known substitutes
- Advanced ceramics: Such as silicon nitride, alumina, and zirconia, offering extreme hardness and high-temperature performance.- Cubic Boron Nitride (CBN): The second-hardest known material after diamond, ideal for high-speed machining of hardened steels.- Polycrystalline Diamond (PCD): Offers the pinnacle of hardness and wear resistance, especially for non-ferrous materials.- Specialized tool steels: Including high-speed steels and advanced powder metallurgy (PM) steels, which provide greater toughness and impact resistance.- Diamond-tipped blades: Used for specific ultra-hard cutting applications.
Comparison Note
Leister Tungsten Carbide Circular Blades provide an excellent balance of extreme hardness, exceptional wear resistance, and good toughness, making them a superior choice over traditional steel blades for continuous, high-intensity industrial cutting. They offer significantly longer lifespan and maintain precision, reducing downtime and replacement costs. While materials like Polycrystalline Diamond (PCD) or Cubic Boron Nitride (CBN) may offer higher hardness for specific applications, tungsten carbide provides a versatile and cost-effective solution for a broad range of demanding cutting tasks, particularly in plastic and flooring applications. Steel blades are generally more affordable and tougher against impact but fall short in wear resistance and edge retention.
