Thank you for your question:
Concentration is a measure of the number of diamond grains (carats) in the bond. Higher concentration improves the abrasive power of the stone. The higher the concentration percentage, the faster the stone works, the less time is spent on sharpening, the less abrasive is used. The lower the percentage of concentration - the slower the stone works, but it works softer. It is the concentration of diamond in the powder that is the most important factor in the performance of a diamond sharpening stone. It is important to note that to increase the hardness of the bond, additional abrasive powders, such as boron carbide, can be added to the bond in addition to the diamond powder, which also affect the performance of the stone.
By definition, diamond powder concentration is the weight content of diamonds per unit volume of diamond layer. The unit of diamond weight is the carat, 1 carat (crt) equals 0.2 grams. Standard diamond bars have relative concentrations of 25%, 50%, 75% and 100% diamond powder.
The diamond powder content is measured in both weight and volume.
PDT stones have a relative abrasive concentration of 100% .
