Multi-grain dresser

Multi-grain dressers have the advantage over single grain dressing diamonds that they wear much more slowly and can be used until they are completely worn out. They are sintered together from grained diamond and metal powder of highly wear-resistant bronze or hard material to form a cylindrical aggregate. The sintered metal cartridge is then soldered into the corresponding holder. With this type of tool, the dressing work is carried out by several small diamonds, which together provide excellent performance. Multi-grain dressers achieve flat surfaces and sharp edges. To achieve good results, the diamond grit should be at least twice the size of the grinding wheel grit to be dressed. Tools with a higher diamond content work more economically.
