Overview
Monocrystalline Diamond Spray
What This Product Is
Monocrystalline diamond spray is a monocrystalline synthetic diamond suspension in a spray applicator. The spray delivers a metered, even dose of diamond onto the polishing cloth, which recharges the cloth quickly and consistently and reduces waste compared with pouring or hand-charging. The diamond itself is single-crystal, giving sharp, predictable cutting for general-purpose polishing.
Intended Use in Metallography
Used for intermediate and fine polishing, the spray form is selected when:
- Fast, even recharging of the cloth is wanted during a polishing cycle
- Consistent, metered dosing matters for repeatable results
- Reducing diamond waste and touch-up time is a priority
- A general-purpose monocrystalline diamond suits the material
Typical Applications
Commonly used for:
- General metals and alloys
- Steels and ferrous materials
- Routine and higher-throughput polishing where quick recharging helps
Beyond metallography, monocrystalline diamond spray is also used in:
- Petrography thin-section polishing
- Ceramics and precision components
- Optics and glass finishing
- Tool and die finishing
When This Product Is NOT Ideal
- When a paste or suspension better suits the existing process
- For hard, mixed-phase materials better served by polycrystalline diamond
- For soft, ductile metals prone to smearing (an oxide final polish may be better)
Where This Fits in the Preparation Process
- After grinding
- Before an oxide final polish, when required
Sprayed onto an appropriate polishing cloth with a compatible lubricant.

Frequently Asked Questions
Why use a diamond spray instead of paste or suspension?
A spray applies a metered, even dose directly onto the cloth, making recharging fast and consistent and reducing waste. Paste and suspension are applied by hand or poured; spray is convenient for quick recharges and repeatable dosing on manual and automated setups.
Water-soluble or oil-soluble spray?
Water-soluble suits most general work; oil-soluble is chosen for moisture-sensitive materials or an oil-based process. Both are offered — see the product options.
Monocrystalline or polycrystalline spray?
Monocrystalline is single-crystal diamond that cuts sharply and predictably; polycrystalline is multi-crystal and self-sharpening, often preferred for hard or mixed-phase materials.
Can monocrystalline diamond spray be used outside metallography?
Yes. The same diamond abrasive polishes hard materials across petrography, ceramics and precision components, optics and glass, and tool and die work. The spray form simply makes even, metered application convenient in any of these.
