Black silicon carbide 24# 36# 54# for Sandblasting of basalt marble tombstones
Black silicon carbide grits in 24#, 36# and 54# are specially produced for sandblasting basalt, marble, granite and stone tombstones, delivering consistent etching and clear engraving effects.
Made from high-purity raw materials with strict particle sizing, these SiC abrasives feature high hardness, sharp cutting edges and superior durability. They efficiently remove surface layers without excessive chipping or cracking, ensuring clean, precise patterns and lettering on hard stone surfaces.
24# grit provides fast rough etching for deep carving; 36# offers balanced speed and finish for general tombstone processing; 54# creates finer, smoother surface textures. With low dust and high reusability, they improve processing efficiency and reduce production costs.
