The 145mm diameter metal cutting blade has a smaller size and more limited cutting depth compared to standard 305mm and 355mm saw blades. However, this does not reduce its market demand. The 145mm saw blade is designed for handheld power tools, enabling more flexible and faster cutting. Additionally, its cermet teeth allow for easier and more efficient cutting compared to conventional carbide teeth.
• Blade Body: Hardened tensioned steel plate resists warping and withstands high-speed metal cutting forces.
• Teeth: Precision-engineered cermet teeth undergo rigorous inspection before robotic welding and grinding, ensuring optimal performance.
• Tooth Geometry: Features specialized TP tooth pattern - trapezoidal teeth create cutting paths while rectangular teeth remove material. This design enhances cutting efficiency and extends blade life.
• Dampening Slots: Laser-engraved slots significantly reduce noise and vibration during operation.
See how our HERO WUKONG CERMET 355mm circle saw blade effortlessly dry-cuts through all kinds of metal.
Compared to standard carbide blades, our cermet blade offers superior heat resistance and cutting performance for continuous dry-cutting of:
• Low/medium carbon steels
• Ferrous metals
• Aluminum and non-ferrous metals
Note: High-chromium alloys and hardened steels may damage the blade. Contact us for specialized blades when cutting high-strength materials.

Our 355mm dry-cut cold saw blades operate optimally at 1,300-1,800 RPM. For best results:
• Use with HERO Brushless Variable-Speed Dry Cut Saws featuring preset RPM modes
• Different materials require specific RPM settings for maximum blade life
• Cutting Pressure Control: Adjust feed speed according to material thickness. Lower tooth counts may deform thin-walled materials - consult our technicians for recommendations.
• Material Securing: Always clamp workpieces securely for safety and cutting stability.
• Angled Cutting: HERO offers specialized dry-cut saws for multi-angle cutting applications.
While blade resharpening can restore some sharpness, it cannot match the original performance. As a factory:
• We offer resharpening services, but international shipping costs make it impractical for single blades
• We recommend purchasing multiple blades for reduced shipping costs per unit
• Wholesale orders receive significant discounts
Here is a list of saw blades we mainly use for metal dry cutting.
Regarding Koocut saw blades: Grade V5 vs. 6000
As a higher-grade blade compared to the 6000, the V5 delivers better cutting performance and longer lifespan. However, this does not necessarily mean the V5 is always the better choice. Higher-grade blades like the V5 require more precise material conditions—the finer the material, the better they perform.
