CBN and diamond sharpening stones 150x25, Premium Economy

Description: DIAMOND AND CUBIC BORON NITRIDE SHARPENING STONES, RESIN AND METAL BONDS150-25-6-3 Length: 150 mm = 6 inchWidth: 25 mm = 1 inchThickness with blank: 6 mm= 0.2 inch Stone thickness: 3 mm= 0.1 inch Quality: - matches quality of products by our competitors with pathetic names; - saves your $. How this product is different from my standard stones (the list of stones is at the bottom of the listing): - blank is thinner (3mm vs 4mm of standard stones) - edges are not beveled, - modest packaging, - stones may need preparation, see below for instructions. We tried to make cost for you as low as possible, but still retain required quality. Many sellers offer these stones as premium. Yes, they are "premium" comparing to competing products, for example to 1.5 mm stones, explained at the bottom of this page.
