Particle mesh size is the number of holes in a 1"-square screen. As the mesh number gets larger, the number of holes per inch increases, the size of each individual hole decreases, and the media becomes finer. Grit refers to coarseness; the lower the number, the coarser the grit.

Steel Shot—Generates a high-impact force to clean and peen heavy forgings and remove heat-treated scale on steel and other cast metals.

Glass Bead—Round beads remove carbon and surface residue for a smooth, bright finish. It is inert and leaves no residue. Peens aluminum and plastic.

Stainless Steel Shot—Outlasts glass bead and Black Beauty grit by a ratio of 1,000 to 1. It descales nonferrous metals and peens aluminum and plastic. Not recommended for removing paint from aluminum and plastic.
