Sharpening Stone for Diamond Drills

By drilling powerfully into the sharpening stone a few times, new spaces are created between the diamond particles, leading to renewed cutting ability - if sharpening does not lead to a positive result, first use the dressing stone - 180 x 70 x 20 mm (7" x 2.25/32" x 25/32") - especially for larger drill diameters and diamond segmented drills
