Direct factory supply manufactured under ISO9001 certification. Optimized for angle grinders, wet saws, and high-speed tile saws.
Understanding diamond grit synthesis, metal matrix sintering physics, and edge geometry engineering for B2B procurement professionals.
In modern industrial fabrication, small diamond blades—typically defined in diameter from 105mm (4 inches) to 230mm (9 inches)—represent the critical link between operator maneuverability and high-speed precision material removal. Unlike large-diameter gang saw blades or 350mm+ bridge saw blades used primarily for primary block splitting, small diamond circular saw blades are engineered for high-RPM handheld angle grinders, masonry cutters, tile table saws, and automated CNC contouring arms.
The fundamental efficiency of a small diamond blade lies in its metallurgical bond matrix and the diamond crystal quality (SDA Grade Synthetic Diamond) embedded within the cutting rim. As a premier manufacturer located in Wuhu, China, and an active member of the China Superhard Material Association, JIAYAN Superhard Tools utilizes advanced computer-controlled hot-pressing sintering and laser-welding technology to balance matrix attrition rates against diamond crystal exposure.
Designed specifically for delicate substrates such as ceramic tiles, glass, and ultra-thin sintered stone slabs. Continuous rim blades provide smooth, chip-free cuts by utilizing a uniform diamond edge without air gaps. Recommended for wet cutting applications.
Features gullets (air slots) engineered between cutting segments to optimize airflow, heat dissipation, and slurry removal. Ideal for rapid dry-cutting of hard materials including granite, reinforced concrete, brick, and asphalt.
Combines the clean finish of a continuous blade with the speed of a segmented blade. The serrated turbo profile actively feeds cooling air/water while channeling debris away from the cutting zone, enabling ultra-fast cuts on marble and hard porcelain.

| 105mm – 115mm (4" – 4.5") | 1.0mm – 1.2mm (Ultra-Thin) | Cobalt-Bronze Micro Matrix | Porcelain Slabs, Ceramic Tiles, Glass Slabs | 11,000 – 13,300 RPM |
| 125mm – 150mm (5" – 6") | 1.4mm – 2.0mm | Iron-Cobalt Hardened Matrix | Granite, Marble Tiles, Quartz Surfaces | 9,000 – 11,500 RPM |
| 180mm – 230mm (7" – 9") | 2.2mm – 2.6mm | Tungsten-Carbide Enriched Bond | Reinforced Concrete, Masonry, Firebrick | 6,600 – 8,500 RPM |
| 260mm – 350mm (10" – 14") | 3.0mm – 3.4mm | High-Density Alloy Matrix | Sintered Stone, Thick Granite Blocks | 3,000 – 4,500 RPM |
Unrivaled supply chain integration, state-of-the-art sintering infrastructure, and direct OEM pricing leverage.
China accounts for over 85% of global synthetic industrial diamond grit production. Located in Wuhu, JIAYAN directly sources high-purity mono-crystalline synthetic diamonds, ensuring consistent grit sharp-edge cleavage and superior diamond concentration per segment.
Our production floor uses fully automated multi-stage vacuum hot-pressing machines. Every blade undergoes strict dynamic balance testing, segment tension checks, and 100% torque shear strength testing in compliance with European EN13236 safety standards.
From custom kerf thickness (e.g., 1.0mm ultra-thin) and bespoke segment height (8mm to 15mm) to laser logo etching and personalized color box packaging, we offer full private-label manufacturing for global distributors and hardware brands.
Insights into shifting architectural materials, cordless power tool evolution, and stringent environmental workplace standards.
Architectural trends have shifted heavily toward large-format porcelain slabs (Sintered Stone / Dekton / Neolith) due to their scratch resistance and non-porous nature. However, these materials harbor internal tension stresses, making them prone to micro-fracturing and edge chipping during cutting. Modern small diamond blades must utilize Ultra-Thin J-Slot & Fine-Mesh Diamond Configurations that operate under reduced friction and lower temperature spikes to deliver pristine, smooth factory edges.
With jobsite mobility moving away from power cords, high-efficiency diamond tools are mandatory. Thinner blade kerfs reduce mechanical resistance against the motor. JIAYAN’s 1.0mm and 1.2mm ultra-thin cutting discs reduce electrical draw on 18V/20V cordless angle grinders by up to 35%, significantly extending battery cycle life per cut.
Urban construction regulations across Europe and North America enforce strict occupational decibel limits. Advanced small diamond blades now incorporate laser-cut anti-vibration slots filled with acoustic damping copper/resin inserts. This mitigates high-frequency resonance, protects operator hearing, and eliminates chatter marks on natural stone edges.
While wet cutting remains ideal for dust suppression, modern fast-paced jobsites demand reliable dry-cutting performance. Advanced laser welding and specialized matrix metallurgy prevent segment loss even when operating under high heat conditions without liquid coolant, boosting jobsite safety and productivity.
Match the exact blade bond hardness and segment design to your regional substrate realities.
Challenge: Cutting expensive 6mm to 12mm thick polished porcelain tiles without chipping the surface glaze.
Solution: JIAYAN 115mm (4.5") Continuous Rim Mesh Turbo Blade. The ultra-fine diamond powder distribution ensures zero glaze spalling, eliminating the need for secondary manual edge grinding.

Solution: 230mm (9") Heavy-Duty Segmented Laser Welded Blade with protective drop-segments. Designed to withstand severe abrasion while resisting matrix undercut.
Understanding the fundamental physical law of diamond tools: Soft Matrix for Hard Materials, Hard Matrix for Soft Materials.
The matrix bond is engineered to wear away at a calculated rate. When cutting hard materials like quartz or hard granite, the matrix must wear fast enough to expose new, sharp diamond grit. Conversely, when cutting abrasive soft materials like sandstone or fresh asphalt, a tough, wear-resistant bronze/nickel alloy bond is mandatory to prevent premature segment erosion.
