Diamond whetstone 200x40x5mm, 48/28µm

Diamond bar 200mm x 40mm x 5mm, M2-01 or M300 bond with 100% diamond concentration, grades of abrasive from ASN to AC15 is designed for manual sharpening of knives and other cutting tools.

Diamond is an abrasive material of exceptional hardness. However, what makes it unique for metal processing is not so much its high hardness as the features of the crystal lattice, which determine the shape of the grain with sharp cutting edges. Even in case of destruction from mechanical influences during sharpening, the diamond grain is not tumbled, but chipped off, forming the same sharp edges. Therefore, a diamond abrasive tool is able to retain its abrasive ability for a very long time during operation.

Another advantage of diamond stones is that they retain the shape of the working surface when sharpening, which makes it easy to form perfect leads even on extremely hard steels.

Diamond bars of the plant "Poltava diamond tool" are monolayer, i.e. uniformly filled in the volume of the product, diamond grain of the appropriate fraction with 100% diamond concentration with powder grades from ASN to AC15. A copper bundle M2-01 or M300 is used.

Before starting operation, it is necessary to open the working layer of the diamond by removing the copper bond from the surface of the bar with medium grit sandpaper. In the future, when the bar loses its abrasive ability during use, it can be restored by etching the working surface in ferric chloride (the places that cannot be etched are painted over with varnish). If several bars of the same size, but different in grain size, are used at once in the work, they must be immediately marked, indicating the grain size, since it is very difficult to determine the difference in grit value tactilely or visually.
