Explore high-yield sintered stone discs, continuous rim porcelain blades, and granite cutting tools engineered for high-RPM automated bridge saws and manual angle grinders.
Modern porcelain slabs and ultra-compact sintered stone materials (such as Dekton, Neolith, and Laminam) represent some of the most challenging abrasives in architectural masonry. Formed through high-tonnage compaction (up to 25,000 tons) and thermal sintering at temperatures exceeding 1200°C, these surfaces achieve a Mohs hardness of 7–8 and maintain extreme internal tension.
Standard diamond saw blades frequently induce micro-chipping, structural blade deflection, and catastrophic thermal fracture when slicing through dense vitrified structures. As an active member of the China Superhard Material Association, JIAYAN Superhard Tools manufactures specialized diamond cutting discs featuring microscopic cobalt-bronze matrix blends, controlled grit friability, and thermal-expansion laser slots.
Leveraging integrated raw diamond synthesis, high-purity metallurgical powders, and automated hot-isostatic sintering for superior global price-to-performance ratios.
Direct supply partnerships within China's domestic synthetic diamond corridor ensure continuous access to uniform MBD-grade high-impact synthetic diamond monocrystals. Every batch undergoes strict thermal stability testing up to 1100°C.
Our Wuhu production facility utilizes computerized vacuum hot-pressing machines operating at 35–45 MPa hydraulic pressure. This achieves 99.8% metallurgical density in cobalt, copper, and iron bond segments, preventing tooth shedding.
Blade steel cores are fabricated from imported 75Cr1 and 65Mn spring alloy steel, heat-treated to 42–46 HRC. Automated laser equipment cuts customized J-slots, keyhole slots, and fish-hook dampeners to neutralize high-frequency acoustic harmonics.

Combining state-of-the-art sintering infrastructure with multi-stage defect screening to deliver ultra-reliable superhard tools worldwide.
Exporting industrial cutting tools demands total adherence to international mechanical safety protocols. All JIAYAN porcelain diamond saw blades and cutting discs are engineered in strict alignment with EN 13236 safety regulations (Safety requirements for superabrasive products) and American ANSI B7.1 standards.
Every production batch is subjected to destructive bursting speed tests up to 150% of the maximum rated RPM, segment shear-strength tests, and ultrasonic flaw detection on welded joints. This guarantees that whether blades operate in continuous wet bridge saw operations in Italy, or dry angle grinding jobsites in the US, risk of segment detachment is virtually eliminated.
Our international fulfillment team provides full customs documentation including Certificates of Origin (Form E, CO), MSDS chemical safety data sheets, and compliant wood pallet heat-treatment markings (ISPM 15).
Certified impact resistance, dynamic core stiffness, and maximum tangential operating velocity compliance (up to 80 m/s).
100% optical inspection of blade rim thickness, segment runout, and metallurgical joint integrity prior to boxing.
From high-speed automated fabrication factories to precision field installation work, our diamond tools adapt across diverse stonework environments.
Cutting large sintered slabs requires precise stress-relief strategies. JIAYAN continuous rim and J-slot 350mm/400mm blades prevent corner blowouts and straight line deviation on 6mm, 12mm, and 20mm ultra-compact panels.
Reinforced sandwich core center plates maintain rigid structural stability under 45-degree lateral pressure, delivering razor-sharp miter edges essential for seamless waterfall islands and countertop returns.

Porcelain and sintered stone possess extreme density and high vitrification without soft calcite fillers. A porcelain blade utilizes a much softer, highly friable metallurgical bond (cobalt-bronze rich) combined with finer diamond grit (70/80 to 120 mesh) that continuously exposes sharp crystal facets, preventing glaze micro-fractures.
Sintered stone releases high internal compressive stress during cutting. J-slots provide controlled thermal expansion relief for the core steel, channel pressurized cooling water straight into the kerf, and disperse harmonic resonance that otherwise causes blade warping and side-chipping.
For 350mm (14") bridge saw blades on 12mm–20mm porcelain slabs, maintain a peripheral speed between 28–35 m/s (approx. 1800–2200 RPM). Recommended feed speed starts at 1.2–1.8 m/min during entry/exit and can accelerate to 2.5–3.5 m/min in continuous straight travel under adequate coolant flow.
