Diamond discs "NIITOP" manufactured by powder metallurgy. The basis of the disc is a bunch of copper, nickel and tin, which ensures its high durability and performance when cutting various materials. The technology used ensures uniform distribution of diamond grains throughout the entire disk volume, from the edge to the mounting hole. Diamond disks are recommended to be used on special high-precision equipment for cutting plates and substrates with a tool rotation frequency of more than 1000 rpm.
