Green Synthetic Diamond Powder features ultra-high purity, razor-sharp crystal facet geometry, and high thermal stability. It is optimized for fine polishing, gemstone bruting, PCD tool lapping, and optical finishing.

Yellow Synthetic Diamond Powder exhibits high impact toughness, blocky crystal structure, and controlled friability under severe mechanical loads, making it ideal for heavy stone cutting, granite gang-saws, and diamond segment tools.

The GDM 92 Series is our premium synthetic diamond grit engineered for heavy-duty saw blades, wire saws, and core drills. It is categorized by strength and thermal stability levels ranging from 9220 (high friability for free-cutting applications) up to 9260 (ultra-high toughness and crystal perfection for reinforced concrete and hard granite sawing).

CBN R (Black Cubic Boron Nitride) features micro-chipping fracture characteristics suited for resin and vitrified bond systems when grinding high-speed steel (HSS) and hardened alloy steels.

CBN A (Amber Cubic Boron Nitride) possesses blocky monocrystalline structure with extreme thermal resistance up to 1400°C, making it superior for electroplated tools, heavy metal bond grinding, and nickel-base superalloys.

Yes. We offer Nickel (Ni 30% / 56%), Copper (Cu 50%), and Titanium (Ti) clad coatings on both diamond and CBN powders. Metal coating enhances heat dissipation, increases mechanical retention in bond matrixes, and extends wheel tool life.

We employ state-of-the-art laboratory testing instruments, including Coulter Multisizer electrical sensing zone systems, Malvern Mastersizer laser diffraction analyzers, optical particle shape analyzers, and high-temperature thermal stability furnaces.

Yes. All micron and mesh size ranges strictly comply with FEPA (Federation of European Producers of Abrasives), ANSI (American National Standards Institute), and ISO standard tolerances for sub-micron, micron, and mesh abrasive sizing.

Every single batch produced at GDM Diamond Tools is issued a lot-specific Certificate of Analysis detailing exact D10, D50, D90 particle size distribution curves, impurity levels, and magnetic susceptibility measurements.

For standard catalog diamond powders and mesh grit, our standard MOQ is 500 carats per size. For custom synthesis, specialized metal coatings, or narrow tolerance micron distributions, the MOQ is 1,000 carats.

We provide commercial sample kits (50 to 100 carats) for qualified tool manufacturers and industrial R&D laboratories. Sample requests can be submitted via our Contact Form or by contacting Mr. Hardik Manani directly at +91 90998 00880.

We ship globally from Surat, India via expedited courier services (DHL Express, FedEx International, UPS) or direct air freight forwarders. We routinely execute contracts under FOB (Free On Board), CIF (Cost, Insurance & Freight), and DAP (Delivered at Place) Incoterms.

We accept International Telegraphic Transfer (T/T Wire), Irrevocable Commercial Letter of Credit (L/C at sight), and secure advance banking transfers. Credit terms may be extended to contracted long-term recurring OEM buyers after credit review.

Yes. Using our proprietary ultrasonic classification and precision air airflow classifiers, we can customize narrow span distributions (tight ratio D90/D10) tailored specifically to eliminate oversize scratch particles in critical lapping compounds.

Yes. We offer confidential OEM packaging, custom batch labeling, vacuum-sealed anti-static bottle containers, and customer-branded COA documentation for overseas abrasive distributors and tool brand owners.
