Tumbling Media for Aluminum, Brass, and Soft Metals


V-Cylinder	Triangle

Pyramid	Granule Corn Cob

Granule Walnut Shell

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 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—Remove tarnish, oxidation, and light scratches to make your parts shine. Ideal for detailed or engraved parts, this media rubs the surface without wearing it down to preserve the shape and sharp edges.

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.

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

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

Pyramid—Reach into even tighter crevices on your workpiece than with triangular media.

Wet Tumbling Condition—Use this media with liquid cleaners.

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.

Walnut Shell—These walnut shells have larger particles than those used for abrasive blasting. They’re cleaned and treated for use in tumblers.

Cleaners for Tumbling

Remove oil, grease, and other contaminants from your workpieces while tumbling. These cleaners trap debris as it’s removed so it won’t deposit onto your workpieces. They also act as a lubricant to improve media rolling and prevent scratches. Dilute with water, then add the solution to your media.
