National Blast Supply
MPN: NBS-GAR80-50
Natural garnet is a semi-angular abrasive that delivers excellent cutting speed with lower dust generation than other aggressive media. 80 mesh is the industry standard for general-purpose blasting — fast enough for heavy rust removal yet clean enough for coating prep. Garnet is non-toxic, silica-free, and environmentally safe for disposal.
