Batch QCThe Right Process for Each Application
Every cutting, drilling, or workshop application places distinct mechanical and thermal loads on a tool. Our engineering team selects the metallurgy, bond matrix, and manufacturing method around your target material and machine parameters, confirming all dimensional tolerances against your drawings before production begins.
Process Matched to Workpiece
Laser welding, hot-press sintering, vacuum brazing, or Cr-V/Cr-Mo alloy forging selected according to concrete cure age, aggregate silica content, stone density, and spindle RPM.
Custom OEM / ODM Engineering
Metric (mm) and Imperial (inch) arbor bores, segment geometries, private-label laser marking, powder-coat finishes, and barcoded export packaging confirmed prior to tooling setup.
Dimensional & Runout Metrology
Calibrated inspection of outer diameter, segment height/width, H7/H8 bore concentricity, steel core lateral runout, and segment weld shear strength (EN 13236 reference).
Lot-Level Production Traceability
Every production lot is tracked from raw diamond grit and alloy heat numbers through sintering/heat-treatment furnace cycles to laser-marked batch codes on dispatched cartons.
Core Product Categories

Verified Before Container Sealing
Every production lot is inspected against your confirmed engineering drawing and order specification prior to release. From metallurgical hardness and segment bond shear testing to final pallet barcoding, verification records are logged per batch.
01 · Dimensional & Dynamic Runout Metrology
Calibrated micrometer and dial-indicator verification of outer diameter, segment height/thickness, H7/H8 arbor bore concentricity, and steel core lateral/radial runout (≤ 0.08 mm – 0.15 mm).
02 · Weld Shear & Metallurgical Proof Testing
Laser-welded and sintered diamond segments undergo torque shear proof testing (referenced to EN 13236 safety standards), matrix Rockwell hardness (HRC) checks, and cutting performance validation on reference granite/concrete blocks.
03 · Batch Traceability & Pre-Dispatch Visual Dossier
Each consignment carries a traceable batch number linking raw material heat lots and furnace sintering logs to pre-shipment dimensional check sheets and packing photos/videos before dispatch to any designated port in China.
Delivery at Any Port in China
We support delivery at any port in China and export to destinations around the world. Export documentation and packing lists are prepared with each shipment.

Frequently Addressed Inquiries
Common questions about process, ordering and delivery.
Manufacturing & ProcessCan you customize diamond bond formulas and manufacturing processes for our regional aggregate?+
Yes. Every tooling order is engineered under a strict process-by-requirement model. Whether your customers cut soft abrasive asphalt, flint-heavy river gravel concrete, reinforced cured concrete, or ultra-hard granite and porcelain slabs, our metallurgical team tailors diamond grit concentration, metal bond hardness, segment geometry, and attachment method (laser-welded, hot-pressed sintered, vacuum-brazed, or alloy-forged) against your confirmed drawings before mass production.
Product SpecificationsDo you supply both North American Imperial (inch) and European Metric (mm) arbor and thread standards?+
Yes. We manufacture complete dual-standard tooling lines. For North American distributors, we supply 4", 4.5", 5", 7", 9", 12", 14", 16", 18", and 20" blades and cup wheels with 7/8"–5/8" arbors, 1" arbors with drive pinholes, 5/8"-11 UNC threads, and 1-1/4"-7 UNC core bit threads. For European and metric markets, we supply 105 mm to 500 mm diameters with 20 mm, 22.23 mm, and 25.4 mm bores, M14 threads, and 1/2" BSP / 1-1/4" UNC core drill fittings.
OEM & ODM CustomizationDo you offer private-label OEM/ODM branding and retail or contractor packaging?+
Yes. We provide end-to-end OEM and ODM private-label execution, including custom powder-coat lacquer colors, laser-etched brand logos, safety pictograms, and SKU part numbers on steel cores, UV screen printing, EAN/UPC barcode labeling, double-blister retail clamshells, color corrugated boxes, and heavy-duty contractor assortment cases.
Quality & InspectionHow do you guarantee quality consistency and 100% pre-shipment inspection across repeat bulk orders?+
Every production batch undergoes 100% pre-shipment verification against agreed drawings—covering H7/H8 arbor bore concentricity, steel core flatness and axial runout, dynamic rotational balance, laser-weld segment shear torque testing, and substrate cutting endurance sampling. Master bond formulas and CAD drawings are archived per customer SKU, with dimensional inspection sheets and pre-loading visual records available before dispatch.
