Synthetic Diamond Powder Guide: Types, Mesh Size and Industrial Applications
Synthetic diamond powder and diamond grit are industrial abrasive materials made from synthetic diamond crystals. They are used in grinding, cutting, lapping and polishing tools where high hardness, controlled particle size and stable abrasive performance are required.
This guide explains the main types of synthetic diamond powder, how diamond mesh size affects tool performance, and how to choose a suitable grade by bond system and application.
What Is Synthetic Diamond Powder?
Synthetic diamond powder is produced from man-made diamond crystals and then processed by crushing, shaping, classification, purification and inspection. Compared with conventional abrasives, diamond powder provides very high hardness and wear resistance, so it is widely used in superhard abrasive tools.
In industrial use, the term may refer to coarse diamond grit for cutting and grinding tools, mesh diamond powder for bonded abrasives, or fine diamond micron powder for precision lapping and polishing.
Diamond Powder vs Diamond Grit vs Diamond Micron Powder
| Term | Typical meaning | Common applications |
|---|---|---|
| Diamond grit | Coarser synthetic diamond particles, often described by mesh size. | Grinding wheels, saw blades, drill bits, polishing pads and electroplated tools. |
| Diamond powder | A general term for synthetic diamond abrasive particles, from coarse to fine grades. | Resin bond, vitrified bond, metal bond and electroplated diamond tools. |
| Diamond micron powder | Fine diamond powder normally specified by micron size for precision finishing. | Lapping, polishing, wire drawing dies, optical polishing and precision surface finishing. |
Main Types of Synthetic Diamond Powder
RVD / RVG Crushed Diamond Grit
Friable diamond grit used for resin bond, vitrified bond and electroplated tools. It is selected when free cutting, self-sharpening and grinding efficiency are important.

Higher strength synthetic diamond powder used for metal bond tools, stone cutting, drilling, sawing and high-load grinding applications.
View MBD diamond powderSMD Synthetic Diamond Powder
General synthetic diamond abrasive powder with controlled crystal shape, strength and particle size for industrial cutting and grinding tools.

Diamond mesh size describes the particle size range of coarse and medium diamond powder. Coarser diamond mesh removes material faster and is often used for cutting, drilling and rough grinding. Finer diamond mesh improves surface finish and is used for fine grinding, polishing and controlled material removal.
| Mesh size range | General behavior | Typical use |
|---|---|---|
| Coarse mesh | High material removal and stronger cutting action. | Saw blades, drill bits, rough grinding and heavy-load tools. |
| Medium mesh | Balanced cutting efficiency and tool surface quality. | Resin bond wheels, vitrified wheels, polishing pads and fickert tools. |
| Fine mesh / micron powder | Better surface finish and more controlled polishing. | Lapping, polishing, drawing dies, optical and semiconductor-related applications. |
How to Choose by Bond Type
| Bond system | Selection focus | Suitable diamond powder type |
|---|---|---|
| Resin bond | Free cutting, self-sharpening, heat control and surface finish. | RVD / RVG diamond powder, selected micron powder. |
| Vitrified bond | Shape retention, porosity, controlled grinding and stable tool life. | RVD / RVG or selected synthetic diamond powder by tool load. |
| Metal bond | High diamond strength, bond holding and cutting life under heavy load. | MBD metal bond diamond powder. |
| Electroplated bond | Particle shape, exposure, nickel holding and sharp cutting edge. | Selected diamond grit or coated diamond powder. |
