Tumbling Media for Steel, Stainless Steel, and Hard Metals

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 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.

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.

Scouring Balls

Remove rust and baked-on grease with a rounded shape that fits naturally in your hand. These balls won’t rust or splinter, so you can use them wet or dry.

Medium Abrasion—Best for general purpose cleaning. Made of brass or copper, these balls are softer than stainless steel balls, so they’re less likely to scratch softer metals, such as aluminum and stainless steel.

Heavy Abrasion—Ideal for challenging jobs. Made of stainless steel, these balls remove rust, oxidation, and baked-on residue. Use them on durable surfaces that can withstand some scratching, such as cast iron and concrete.

Extra-Heavy Abrasion—Deliver an intense clean for the most demanding jobs. Made of stainless steel, these balls remove corrosion and break down thick grime buildup on the most durable surfaces that you aren’t afraid to scratch.
