What is Crushed Diamond Powder?
Crushed diamond powder is a high-performance industrial abrasive made by mechanically crushing and carefully grading synthetic single crystal diamond powder. Produced from industrial diamond materials, it features sharp, multi-angular particles with controlled size distribution, typically ranging from 50/60 to 500/600 grit. This irregular, blocky structure provides excellent cutting edges, good self-sharpening ability, and high grinding efficiency.
At Crownkyn Diamond, we manufacture crushed diamond powder under strict quality control standards to ensure uniform particle shape, stable size distribution, and low impurity levels. Our products are widely used in resin bond, vitrified bond, and metal bond tools, as well as electroplated products, for the grinding and cutting of stone, ceramics, hard alloys, and other difficult-to-machine materials.

How to Select the Right Crushed Diamond Powder
STEP 1
Define Your Application
Start by identifying whether the powder will be used for cutting, rough grinding, fine grinding, or polishing. This determines the required grit size and particle performance.
STEP 2
Choose the Appropriate Grit Size
Select the grit range based on your processing needs—coarse sizes (50/60–120/140) for heavy material removal, medium (140/170–230/270) for general grinding, and fine (270/325–500/600) for finishing and surface preparation.
STEP 3
Match the Bond System
Ensure compatibility with your bond type. Resin bonds favour sharp, self-sharpening particles; vitrified bonds need stable blocky crystals; metal bonds require wear resistance; electroplated tools demand angular particles for firm bonding.
STEP 4
Select the Particle Type
Choose from standard crushed for general use, shaped crushed for better uniformity and grinding stability, or coated crushed (Ni, Ti, Cu) for enhanced bond retention and heat resistance in demanding applications.
STEP 5
Consider the Processed Material
Select the appropriate diamond powder based on the material you are processing, such as stone, ceramics, hard alloys, glass or gemstones, to ensure optimal cutting performance and extended tool life.
STEP 6
Request Technical Support or Samples
If unsure, Crownkyn’s technical team can assist with selection and provide samples for evaluation to ensure the solution meets your production needs.
Consistency and Quality Control
At Crownkyn, we prioritise consistency and quality across every batch of crushed diamond powder to ensure stable performance in your production.
Strict Grading Standards: Each product is classified using precision sieving equipment and laser particle size analysers to ensure uniform particle size distribution and shape for predictable grinding behaviour and consistent tool performance.
Low Impurity Content: We use inductively coupled plasma (ICP) analysis and X-ray fluorescence (XRF) to detect and control trace impurities, ensuring high material purity and minimising the risk of contamination.
Stable Crystal Structure:Through scanning electron microscopy (SEM) and optical microscopy, we monitor the crystal shape and crushing quality to maintain sharp cutting edges and consistent wear characteristics.
Batch-to-Batch Reliability:All batches undergo visual inspection, magnetic separation, and sample testing to confirm performance consistency, helping you maintain process control and reduce production variability.
