Diamond plates on galvanic bond provide intensive metal removing and can be used for the cutting edge with significant damage (chips, bends etc.). Diamond plate F80-120 Extra Coarse is used for rough grinding of the edge and by forming the shape of the blade. Diamond plate F200-400 Coarse is used for forming the cutting edge. Diamond plate F500-600 Medium is used for main sharpening operations and creating the aggressive cut. Diamond plate F800-1000 Fine is used for pre-finishing of the cutting edge and removing of noticeable marks. Diamond plate F1500-3000 ​Very Fine is used for finishing the cutting edge. They work much more aggresively than stones on organic or metallic bond with the same grain size. Its achieved by protruding diamond grains, whereas grais in organic or metallic bond are suck in the binder and mixed with it. The grain concentration in a layer is 100%. Although it should be noticed that these stones will give in to other stones in duration of work because of thin coating, which will actively remove while sharpening. You also should remember, that by working with soft steels (up to 58 HRC) these diamond stones will work out faster than by working with harder steels. Diamond stones on galvanic bond dont require preparing for work (levelling, "cheering up" etc.). Abrasive dimensions: 4х20х150 mm
