Abrasive Blasting Media

Remove paint, coatings, and rust or add texture to surfaces. This media is suitable for use on a wide variety of surface materials.

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.

Glass/Aluminum Oxide Grit

Image of Product. Front orientation. Abrasive Blasting Media.

A mixture of glass bead and aluminum oxide grit, this media is less aggressive than pure aluminum oxide grit. It’s tough enough to clear away corrosion but gentle enough to etch aluminum and plastic without gouging them.

Low Reusability—Effective for a handful of cycles under normal blasting conditions.

Aluminum Oxide Grit

The grit you think of for sanding, grinding, and polishing. As abrasive blasting media, aluminum oxide grit does it all—from blasting away paint to frosting glass to deburring and etching metal. It’s hard and has sharp, angular edges for fast cutting. It won’t leave behind contaminants like steel grit, so it can be used on a wider variety of materials.

Low Reusability—Effective for a handful of cycles under normal blasting conditions.

MIL-A-59316—This grit meets strict standards for particle size, shape, and material quality. It’s certified to remove enough scale, rust, and paint that a metal surface is ready for processing.
