The bar is suitable for basic sharpening.
Side 160/125 is made on an organic bond B2-01. Organic ligament consists of phenol-formaldehyde resins and various compositions based on them. Which, during hot pressing, are Bakelized into a solid and sufficiently strong substance that holds the cutting grains in the working layer of the tool. Moreover, such a bundle will be sufficiently strong and vicious, but not rigid enough. To give it rigidity, abrasive grinding powders, such as boron carbide, are added.
Side 100/80 is made on the new upgraded OSB bundle. The difference between the OSB bundle and the others is that it does not use boron carbide. In addition, the abrasive layer on it does not sinter but sticks to the body of the metal plate. The absence of extra impregnations of other abrasives makes it possible to do softer and finer work. Already out of the box, such a bar is ready for use; it does not require alignment on silicon carbide. The OSB bond is ideal for hard steels at small angles.
