What mesh sizes are available for GDM Green and Yellow Diamond Powders?

Available sizes range from 20/25 to 500/600 mesh, alongside micron classifications from 0-0.25 to 30-40 micron.

What is the difference between 9220, 9240, and 9260 Saw Cutting Diamond Series?

9220 is a low-grade irregular diamond for light polishing, 9240 is middle-high strength for marble & granite saws, while 9260 features maximum thermal impact stability for geological mining tools and reinforced concrete wire saws.

Synthetic Diamond Powders & CBN Catalog

Green Diamond Powder

Features a distinctive green tint, moderate toughness, strong thermal stability, and excellent self-sharpening properties. The irregular, angular crystal shapes provide aggressive micro-abrasive cutting action. Designed primarily for resin and vitrified bond systems.

Ideal Applications

Grinding wheels for tungsten carbide, glass, and ceramics; granite/stone profiling and surface polishing.

Available Size Range

50/60 Mesh 80/100 Mesh 120/140 Mesh 200/230 Mesh 325/400 Mesh 500/600 Mesh 0-0.25 to 30-40 Micron

Yellow Diamond Powder

Features a clear yellow appearance with high friability parameters. Under mechanical load, the sharp-edged crystals micro-fracture to reveal new cutting margins, ensuring high material removal rates and cool grinding conditions.

Ideal Applications

Fired tungsten carbide and hard alloy grinding; magnetic components; gemstone shaping and dental burrs.

Available Size Range

20/25 Mesh 40/50 Mesh 70/80 Mesh 100/120 Mesh 230/270 Mesh 325/400 Mesh 0-0.25 to 30-40 Micron

Resin Bond & RVD-P

Economical synthetic diamond raw material. Sharper than standard alternatives, it is engineered for high friability, self-sharpening capabilities, and strong adhesion in resin matrices. Suitable for fragile non-metallic workpieces.

Ideal Applications

Resin and vitrified grinding wheels; processing stones, ceramics, glassware, and tungsten carbide.

Available Size Range

80/100 Mesh 120/140 Mesh 200/230 Mesh 270/325 Mesh 325/400 Mesh 0-0.25 to 30-40 Micron

Micron Diamond Powder

High-strength RVD diamond raw material processed to a narrow particle size distribution (PSD). Features low impurities, high wear resistance, and strong grinding force. Designed for super-finishing and lapping.

Ideal Applications

Super-finishing, lapping, and polishing sapphire, gemstones, quartz, electronic components, and PCD/PDC dies.

Available Size Range

0.5 Micron 1.0 Micron 3.0 Micron 6.0 Micron 15.0 Micron 30.0 Micron 60.0 Micron

9260 & 9280 (High Strength)

Consists of consistent crystal color, highly blocky and regular shapes, high transparency, and superior thermal impact stability (TT/TI). Designed to resist cracking when embedded in metallic matrices.

Ideal Applications

Geological core drills, mining tools, wire saws for concrete, large circular saws for granite.

Available Size Range

30/35 Mesh 35/40 Mesh 40/45 Mesh 45/50 Mesh 50/60 Mesh

9240 (Middle-High Strength)

Features regular crystal shapes with good compact strength and thermal stability. Ensures balanced grinding efficiency and tool life in standard stone slicing operations.

Ideal Applications

Multi-blade saws for marble and granite; dry cutting segment blades; geological drill segments.

Available Size Range

30/35 Mesh 40/45 Mesh 50/60 Mesh 70/80 Mesh

9220 & 9230 (Standard Strength)

Designed for low-to-medium load applications. 9220 features irregular crystal shapes for low-load polishing, while 9230 offers comparatively regular shapes with good compact strength for uniform crystal structure tools.

Ideal Applications

Marble calibrating electroplated rollers, frame saws, and marble polishing wheels.

Available Size Range

30/35 Mesh 40/45 Mesh 50/60 Mesh 70/80 Mesh

CBN R (Black)

Black superhard monocrystalline abrasive featuring high toughness and thermal stability. Its irregular, sharp angular shape provides outstanding self-sharpening and high grinding efficiency on ferrous materials.

Ideal Applications

Grinding hardened steel (HRC 45+), high-speed tool steel, bearing components, and automotive engine parts.

Available Size Range

40/50 Mesh 80/100 Mesh 120/140 Mesh 170/200 Mesh 230/270 Mesh 325/400 Mesh

CBN A (Amber)

Premium amber-colored superhard abrasive. Features semi-blocky crystal shapes, medium-high strength, excellent thermal stability, and superior impact resistance. Balances toughness with self-sharpening parameters.

Ideal Applications

Precision grinding of hardened alloy steels; vitrified bond tools; superalloy grinding in aerospace components.

Available Size Range

40/50 Mesh 60/70 Mesh 100/120 Mesh 140/170 Mesh 200/230 Mesh 325/400 Mesh
