For a high removal rate ? aggressive silicon carbide grain The Kronenflex grinding discs C 24 R Supra for stone/concrete are furnished with SiC grain to provide for a high removal rate. The structure of this grain is coarse and sharp, resulting in a high level of aggressiveness. Since SiC grain is also friable, grains that have become dull will be shed from the structure. Dull grain thereby makes room for new and sharp grain. All grain used by Klingspor is the product of a synthetic manufacturing process. The grain is therefore guaranteed to retain its qualities and produce the same excellent results throughout its lifetime even if subjected to heavy-duty applications.
