Engineered with micro-grain structural integrity and advanced matrix metallurgical bonding for clean, rapid cuts across abrasive and dense surfaces.
Why cordless field tooling, compact track saws, and specialized sub-compact cutting discs dominate industrial and commercial renovation workflows worldwide.
The global transition to 18V/20V brushless cordless circular saws has elevated the 5.5-inch (136mm–140mm) form factor into a key tooling category. Thinner kerf profiles reduce frictional drag, drawing up to 35% less battery amperage per linear foot cut while extending motor cycle life.
Traditional blades struggle against modern sintered stone, quartzites, and fiber-reinforced cement boards. Specialized 5.5-inch continuous-rim and turbo-mesh designs provide micro-chipping protection and maintain pristine edge geometry on premium, brittle materials.
Major hardware brands, specialty tool distributors, and industrial supply houses require unified OEM manufacturing partners able to deliver laser-cut tensioned cores, custom arbor configurations (e.g., 20mm, 5/8", 10mm), and certified runout balancing below 0.05mm.
JIAYAN Superhard merges advanced metallurgy with automated production protocols, offering Tier-1 contract manufacturing directly from Wuhu, China.
We deploy high-precision German-engineered sintering furnaces and hot-press matrices to fuse fine industrial diamond grits (Mesh 40/50 to 70/80) with engineered cobalt, copper, and bronze powders, achieving uniform bond density and high wear resistance.
To eliminate wobble and blade wander at operating speeds exceeding 9,000 RPM, every 75Cr1 high-carbon steel core undergoes roller-tensioning, precision surface-grinding, and optical runout audits to stay within 0.03mm-0.05mm axial tolerance.
As an active member of the CSMA, JIAYAN adheres to international tool testing safety measures (EN 13236 compliance standards), driving innovations in segment geometry, noise-dampening laser slots, and eco-friendly electroplating.
| Blade Class / Diameter | Core Specification | Diamond / Tip Matrix | Primary Working Material | Cutting Efficiency |
|---|---|---|---|---|
| 5.5" (140mm) Thin Kerf Sintered | 1.0mm 75Cr1 Annealed Core | Ultra-Fine Micro Mesh / Cu-Co Bond | Sintered Stone, Porcelain Slab, Ceramic Tile | Clean Edge (Zero Chip) |
| 5.5" (136-140mm) Turbo-Rim | 1.2mm Corrugated Cooling Body | Industrial Synthetic Monocrystal 50/60 | Granite, Compact Terrazzo, Quartzite | Fast Advance (+30%) |
| 350mm (14") High-Bridge Segmented | 2.2mm Laser Cut Core / Keyhole Gullet | Structured Segment Array / Cob-Bronze | Structural Granite, Engineered Stone Slabs | Heavy-Duty Industrial |
Engineered for precise depth penetration and clean line control across field construction, architectural fabrication, and industrial installations.
Ideal for 5.5-inch corded/cordless portable plunge saws cutting large-format porcelain stoneware (gauged porcelain panels). The continuous rim eliminates chipping on polished, glazed, or vitrified faces.
Contractors utilize 5.5" diamond circular blades for tight sink cutouts and miter joints directly on the job site, reducing edge chipping and eliminating micro-fractures prior to mechanical edge profiling.
With custom PCD (polycrystalline diamond) or sintered diamond configurations, 140mm blades withstand the high abrasion of fiber cement siding, generating uniform score lines and managing respirable crystalline silica.
Our reinforced 5.5-inch tuck-point and slotting discs clear out cured mortar joints, decorative expansion grooves, and control joints in commercial concrete floors with stability and tracking control.
Technical validation and global presence across premier ceramic machinery and superhard tooling conventions.

We supply standard 20mm bores, 5/8" (15.875mm) round arbors with diamond knockout knockouts, 10mm arbors for mini battery saws, and custom pinhole patterns for European and North American cordless saw hubs.
For ultra-dense sintered stone and hard granite, we use softer bronze-cobalt bonds that release worn diamond crystals quickly to prevent blade glazing. For abrasive materials, we deploy harder nickel-tungsten alloys to protect segment longevity.
For custom laser etching on steel cores, our MOQ starts at 100 units. For fully customized retail packaging (color boxes, blister packs with barcode labeling), our standard production batch threshold starts at 500 units per SKU.
Every production run undergoes axial runout verification, dynamic spin-balance testing up to 1.5x maximum working RPM, and hydraulic segment torque shear checks complying with EN 13236 superhard cutting tool standards.
