BUYING GUIDE
Rock Tumbling Media
Compare rock tumbling media by documented material, shape, size wording, intended job, machine method, preparation, and stage history. Ceramic pieces and plastic pellets require different records; a broad compatibility claim cannot replace the exact machine and media instructions.
Before you choose
- Define the job: filler, cushioning, contact support, abrasive delivery, or another documented purpose.
- Copy ceramic or plastic material, shape, dimensions, package quantity, and mixed-size wording from the exact source.
- Record whether the media is new, broken-in, stage-dedicated, cleaned, damaged, contaminated, or unknown.
- Match the exact rotary or vibratory machine instructions for supported media, load, moisture, and inspection.
THE TRADEOFF THAT MATTERS
Match the listing to your process.
Reusable media can reduce waste and help maintain a documented load, but reuse creates a history that must be preserved. Unknown prior grit, new rough edges, or an unsupported machine method is a reason to quarantine the media—not a reason to add it and hope.

Choose by material, stage history, and machine method
The 14 approved records below include five mixed refill bundles and nine standalone ceramic listings. The current catalog has no approved standalone plastic-media record. A saved title can identify package contents, size wording, or a material claim, but it cannot establish the handling rules for an undocumented batch.
Copy the exact material and size
Keep ceramic versus plastic, shape, stated dimensions, package weight, and mixed-size wording attached to the product source.
Preserve stage history
Label prior abrasive stages, cleaning, condition, and intended next use. Unknown history means quarantine, not polish-ready.
Match the exact machine
Rotary and vibratory workflows differ. The machine manual controls supported media, load, moisture, inspection, and mounting.
Mixed refill kits that include media
These five approved records combine media with grit, polish, or other supplies. Confirm which material is included, its quantity, preparation, and stage assignment; a bundle does not make every component suitable for every stage.
