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.

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.
