Diamond sharpening stones PETROGRAD bars are intended for processing high-carbon steels and cast iron products. Diamond bars are monolithic sharpening with a continuous flat diamond layer. The diamond-bearing layer of the bars is made of synthetic diamond micropowders on a copper-tin bond M2-01.
The relative concentration of highly aggressive synthetic diamonds (ASD) is 100%.
Aggressive diamonds provide high productivity. Also, the bars have high abrasion resistance.
Diamond stones do not need to be soaked in water prior to use as they do with abrasive stones, but should be handled with honing oil or water.
Diamond bars are monolithic six-sided, therefore 6 sides are working.
