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.

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 Bead

The most widely used abrasive blasting bead, glass bead cleans away rust and surface residue from any material to leave a smooth, bright finish. It has a round shape to peen soft materials such as plastic and aluminum, though it’s not hard enough to peen steel and stainless steel.

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

MIL-PRF-9954—This media meets strict standards for particle size, shape, and material quality. It's certified to remove enough scale, rust, and paint to prep metal surfaces.

SAE AMS2431/6D—Blast surfaces to a predictable, repeatable finish every time. This glass bead meets tighter tolerances for size, shape, and quality than bead rated MIL-PRF 9954.

Ground Glass

A more aggressive alternative to glass bead, this angular abrasive blasts harder and leaves a rougher finish. It’s most often used to clean bricks, cement, and other masonry that’s already rough. While moderately aggressive, it’s still gentle enough to etch aluminum, plastic, and other soft materials without gouging them.

Not Reusable—Typically only effective the first time it's used.

Glass/Aluminum Oxide Grit

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.

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.

Superoxalloy Grit

A safer, tougher alternative to aluminum oxide grit. Made from mineral wool, this grit produces less dust than aluminum oxide grit because it resists fracturing from impact better. The small amount of dust it does create is safely dissolved in human lungs, so it’s not classified as a carcinogen according to International Agency for Research on Cancer (IARC). Thanks to its rounded edges, this grit won’t embed into surfaces as frequently as other grit for a clean surface that’s ready for your next process.

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

MIL-PRF-22262C—This grit meets strict standards for particle size, material quality, and cleaning efficiency. It’s certified to remove enough scale, rust, and paint to prep metal surfaces.

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.

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.

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.

Sodium Bicarbonate (Baking Soda)

Image of Product. Front orientation. Contains Annotated, Inset. Abrasive Blasting Media. Abrasive Blasting Media for Delicate Materials, Sodium Bicarbonate (Baking Soda).

The least aggressive blasting media, baking soda scours almost any material without scratching or marring it. It’s also the best choice for cleaning and removing paint from wood. Wash it away using only water.

Not Reusable—Typically only effective the first time it's used.

Walnut Shell

Gentle abrasion without damage. Not only will walnut shells clean, but they also polish and debur thanks to their slight abrasion.

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

Plastic Grit

Slightly more aggressive than walnut shells and corn cob, plastic grit removes tougher coatings and buildup without marring and warping. It also stays effective for twice as many cycles as corn cob and walnut shells.

Medium Reusability—Effective for dozens of cycles under normal blasting conditions.

Dolomite

Image of Product. Front orientation. Contains Annotated, Inset. Abrasive Blasting Media. Abrasive Blasting Media for Delicate Materials, Dolomite.

Delicately clean hard materials such as brick, stone, and concrete. Originally used to restore the surfaces of fossils and historic monuments, dolomite is hard enough to clear grime and years of weather from masonry yet delicate enough not to gouge it. It’s not recommended for soft metals and plastics.

Not Reusable—Typically only effective the first time it's used.
