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.

Ceramic Bead

The hardest, longest-lasting bead abrasive we offer. This round abrasive stays effective for 500 times more cycles than glass bead while delivering the same smooth finish. Since it’s harder than glass and bauxite bead, it easily peens steel, stainless steel, and other hard metals. It’s also virtually dust-free, so you'll find it used in medical, aerospace, and other dust-sensitive environments.

High Reusability—Effective for hundreds of cycles under normal blasting conditions.

Ceramic Grit

Your pick for long lasting, dust-free grit. It lasts for 500 times more cycles than aluminum oxide while leaving a similar finish. It’s also virtually dust-free, so you'll find it used in dust-sensitive environments such as medical and aerospace spaces.

Tumbling Media for Steel, Stainless Steel, and Hard Metals

V-Cylinder

Cylinder

Triangle

Ball

Made of a hard material, this tumbling media is tough enough to finish steel, stainless steel, and other hard metal parts. 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 Smooth Finish—Aggressively remove burrs and blend grind lines. This media leaves a matte finish and typically needs a follow-up for final smoothing.

For Extra-Smooth Finish—Common for general use, this media deburrs and rounds edges while preserving surface details. It removes a moderate amount of material to leave behind a matte finish.

For Ultra Smooth Finish—Gently deburr and blend with minimal edge rounding. This media lightly removes material for a sleek, satin finish.

For Polished Finish—Rub your parts without wearing them down—this media creates a shiny finish. It doesn’t remove surface material, so your parts retain their shape and sharp edges.

For Mirror Finish—Use this media as the final step in your finishing process to create a reflective finish. Ideal for fragile parts, it rubs the surface without removing material.

V-Cylinder—A good all-around choice for flat surfaces, slots, corners, grooves, and holes. V-cylinders are a hybrid between cylinders and triangles.

Cylinder—Best for large, open surfaces such as cube faces, and flat parts with holes such as washers.

Triangle—Reach into slots, corners, grooves, and holes without getting stuck.

Ball—Best for gentle finishing. Balls are less aggressive than other shapes, so they smooth your workpiece without flattening any details.

Wet Tumbling Condition—Use this media with liquid cleaners.

High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Balls

Often used instead of metal in bearings and rollers, these balls are ideal for applications where strength under heavy loads and wear resistance is needed. It's the addition of yttria that gives this zirconia more strength and lowers the chances of cracking from impact than standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of the material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.

These balls do not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics such as ceramic alumina and silicon nitride ceramic.

Fracture- and Thermal-Shock-Resistant Silicon Nitride Ceramic Balls

Often used to create bearings, silicon nitride ceramic is harder than many types of bearing steel but is lightweight and can be easily polished. It also withstands high temperatures.

Acid-Resistant Silicon Carbide Ceramic Balls

Extremely hard with excellent corrosion resistance, this silicon carbide ceramic is often used for rubbing parts such as bearings and bushings in chemical-processing environments. This material’s hardness means it resists abrasion and wear, but also makes it more brittle than other ceramics. Don’t use it under heavy loads or at high speeds. Nearly chemically inert, it resists corrosion better than other ceramics when in contact with acids and other chemicals. Silicon carbide ceramic conducts heat well and doesn’t expand significantly from heat, so it won’t deform or crack from temperature swings. Rated for use at up to 2550° F, it’s good for use in furnaces and refractories.
