Manufactured using advanced hot-pressed sintering and automated laser-welding to deliver zero-chipping performance, exceptional thermal resistance, and maximum lineal cutting yield.
As the construction and fabrication industries shift toward lightweight, high-mobility brushless power tools, procurement teams demand next-generation 85mm blades with tighter tolerances and higher thermal thresholds.
Modern mini circular saws operate on 12V and 18V Li-ion battery platforms where frictional drag directly affects motor amp-draw and battery runtime per charge cycle.
High-end building materials like sintered porcelain slabs, Dekton, and vitreous ceramics possess internal residual stresses that fracture under conventional cutting shocks.
Tier-1 hardware brands, retail chain importers, and industrial tool houses require agile OEM/ODM manufacturing pipelines with automated QA checkpoints.

Compact 85mm circular cutting systems have expanded beyond basic DIY carpentry into specialized high-precision applications in aerospace interiors, luxury tile setting, and industrial retrofit operations.
Compact cordless plunge saws equipped with JIAYAN 85mm J-slot continuous blades allow tilers to execute plunge cuts, flush edge trims, and precision electrical outlet cutouts directly on installed porcelain without cracking fragile edges.
Contractors operating in confined ceiling cavities or drylined wall partitions utilize 85mm thin-kerf diamond blades to sever drywall, fiber cement backing boards, and light-gauge copper tubing cleanly with zero combustible sparking.
Ultra-thin 85mm circular saw discs slice through high-pressure laminates (HPL), solid surface acrylic corian, and carbon-fiber reinforced polymers (CFRP) with zero delamination and mirror-like cut edges.
Equipped with specialized electroplated or vacuum-brazed diamond formulations, 85mm blades safely cut stainless steel profiles, conduit, and soft copper without burrs, eliminating hazardous abrasive disc shattering risks.
JIAYAN Superhard invest 7.8% of annual turnover into synthetic diamond metallurgy and advanced automated sintering to continuously redefine tool lifespan and environmental sustainability.
Developing 0.85mm – 0.95mm ultra-thin kerf 85mm saw blades using laser-tensioned 75Cr1 steel cores. Reduces dust particulate mass by 32% and extends battery runtime on mini 12V circular saws by up to 45% per battery charge.
Applying physical vapor deposition (PVD) titanium silicon nitride coatings directly over segment rims. This reduces coefficient of friction from 0.45 to 0.18, virtually eliminating resin melting and glaze adherence during composite cutting.
Migrating proprietary three-dimensional diamond crystal distribution into micro-diameter 85mm blades. Ensures every individual diamond grain experiences uniform mechanical load, doubling lineal tool lifespan while maintaining rapid feed speed.
Headquartered in Wuhu, China, JIAYAN Superhard Tools is an active member of the China Superhard Material Association. With over a decade of international trade and supply chain integration, we operate automated hot-pressing sintering lines, multi-axis automated grinding cells, and computerized laser dynamic balance stations.
Our OEM/ODM manufacturing facility supplies verified diamond saw blades and cutting discs to leading distributors across Europe, North America, Oceania, and Southeast Asia. Every shipment adheres strictly to global industrial safety certifications including EN 13236, ANSI B7.1, and ISO 9001:2015 quality management frameworks.
Critical metallurgical, operational, and commercial insights to streamline your 85mm circular saw blade sourcing decisions.
The most common arbor bore for compact 85mm circular saws (such as cordless mini saws manufactured by Bosch, Makita, Worx, and Ryobi) is 15mm. However, JIAYAN provides customizable inner bore diameters including 10mm, 15.87mm (5/8"), and 20mm, equipped with precision CNC-machined brass reduction rings for versatile multi-tool compatibility.
Hot-pressed sintering applies simultaneous hydraulic pressure and high-temperature thermal fusion to the cobalt-bronze matrix. This creates a homogeneous, ultra-dense metallurgical bond that holds fine grit (#180–#220) diamonds tightly, preventing premature pullout and ensuring chip-free chip discharge on delicate vitreous porcelain slabs.
An 85mm diamond blade is typically rated for a maximum safe rotational speed of 17,500 RPM (peripheral speed ≈ 78 m/s). Optimal operating speeds on 12V–18V cordless plunge units hover between 1,400 RPM and 4,500 RPM, depending on whether dry or wet cutting coolants are implemented.
Every 85mm disc is manufactured from laser-cut 75Cr1 high-carbon alloy plate, heat-flattened, and subjected to automated dynamic balancing. We enforce a strict axial runout limit of ≤ 0.03mm, minimizing mechanical stress on cordless motor bearings and preventing edge breakout.
Our standard MOQ for private-label OEM manufacturing (custom laser logo, bespoke segment formula, and retail packaging) starts at 500 units per specification. For standard neutral-stock or testing batches, we support trial shipments beginning at 100 units.
Yes. JIAYAN 85mm diamond blades feature engineered hot-pressed cobalt matrices and radial venting expansion slots that dissipate heat efficiently during dry cutting. When combined with water delivery, cutting life increases by up to 2.8 times with absolute dust elimination.
