Hollow Ground Blades

Shengao Hollow Ground Blades are crafted from premium materials to ensure exceptional durability and cutting performance:

• High-Speed Steel (HSS M2/W18): Ideal for precision cutting with excellent edge retention and heat resistance (HRC 62-66) for laminate, melamine, and coated materials
• Tungsten Carbide: Superior wear resistance (HRA 90-92.5) for cutting abrasive composites and extended blade life
• Alloy Steel: D2, 9CrSi, and Cr12MoV grades provide optimal toughness and durability for high-volume cutting operations
• Specialty Coatings: TiN, TiCN coatings reduce friction, prevent material adhesion, and resist corrosion for smoother operation

Each material undergoes specialized heat treatment and cryogenic processing to achieve optimal hardness while maintaining toughness for precision cutting applications.

Selecting the appropriate hollow ground blade depends on several key factors:

1. Material Type: Different materials (laminates, melamine, acrylics, composites) require specific blade compositions and edge geometries
2. Material Thickness: Thicker materials require blades with appropriate hardness and concave edge geometry
3. Production Requirements: High-speed applications need blades with enhanced heat resistance and specialized steel grades
4. Cut Quality: Precision applications require blades with optimal hollow grind depth and specialized coatings
5. Machine Compatibility: Ensure proper fit for vertical panel saws, sliding table saws, and precision cutting systems

Our technical team provides customized recommendations based on your specific requirements and machine specifications.

Proper maintenance extends blade life and ensures optimal cutting performance:

• Regular Cleaning: Remove resin buildup and debris after each use to prevent adhesion and maintain cutting precision
• Periodic Sharpening: Maintain concave edge geometry using appropriate grinding equipment and techniques for HSS materials
• Proper Storage: Store blades vertically in dry, temperature-controlled environments with protective coatings
• Rotation Practice: Rotate blades in multi-blade systems to ensure even wear and consistent performance
• Coating Maintenance: Inspect and maintain specialized coatings (TiN, TiCN) for optimal non-stick performance

Shengao offers professional sharpening services and provides detailed maintenance guides with every purchase.
