    Abrasive Blasting Media for Delicate Materials

    Remove paint, coatings, and rust from delicate materials. Softer than other abrasive blasting media, this media cleans away contaminants without scratching or marring the underlying surface. It is a good choice for finishing soft metals, plastics, wood, or sensitive equipment.
    Our abrasive blasting materials are sorted from least to most aggressive. The more aggressive the media, the more material it removes from your surface.
    Both particle mesh size and grit measure the size of the abrasive particles. The higher the number, the finer the particles are.

    Clean without abrasion—corn cob is gentle enough to clean wood, fiberglass, plastic, and masonry without causing damage. It won't frost glass, pit aluminum, or raise grain on wood.

    Granule

    Corn Cob

    Made of soft material, this tumbling media gently finishes aluminum, brass, and other soft metal parts without distorting them. Choose the shape that best matches the contours of your part and a size that’s large enough not to get stuck in recesses and holes. You can also mix shapes and sizes to tailor the finish to your part.
    For Polished Finish—Often used as the final step in finishing, this media brightens your part’s surface with an extremely shiny finish. It rubs the surface without wearing it down to preserve the shape and sharp edges.
    Dry Tumbling Condition—Run this media dry and it won't stick to your parts. Dry media simplifies setup and cleanup, but it takes longer to finish your parts than wet media.
    Corn Cob—These corn cobs have larger particles than those used for abrasive blasting. They’re cleaned and treated for use in tumblers.
