Product Description
Engineered specifically for ultra-deep structural cutting in concrete and masonry. Utilizing a centerless drive system, this lightweight ring saw blade achieves remarkable cutting depths of 280mm to 300mm. With pre-factory stress testing and a offset segment-to-core thickness design, it effectively minimizes pinching while delivering exceptional cutting speed and operator comfort.
280mm–300mm Ultra-Deep Cutting Capabilities
Reaches cutting depths up to 280mm–300mm in a single pass—nearly double the depth of standard conventional circular blades. Perfect for deep door/window openings, thick concrete walls, and pipe sectioning
Factory Stress-Tested Core & Offset Clearance Prevents Binding
Every blade undergoes rigorous stress testing before leaving the factory to ensure optimal core tension under deep cuts. Built with a 4.2mm segment on a 3.2mm steel core, the side clearance prevents blade pinching or preventing blade pinching during deep cuts.
Precision Drive-Slot Alignment & Complete Machine Matching
Engages seamlessly with matching drive wheels to prevent wheel slippage and power loss. Driveshaft-compatible or drive wheels can be supplied upon request, and complete ring saw machine matching packages are available for single-source procurement.
Lightweight Design & Sharp Matrix for Fast Penetration
Combines a lightweight, well-balanced core with a high-sharpness diamond formula. Reduces operator fatigue during prolonged vertical or handheld operations while ensuring quick, clean cut-throughs to keep projects on schedule.
Full OEM & ODM Customization
Break free from standard designs. Custom segment height/thickness, core thickness, matrix formulas, and aesthetics tailored to your market. Just share your logo, and we’ll deliver free visual branding for your blades.
