Rock Tumbler Grit & Polish
Grinding abrasive and final polish do different jobs. Shop for a clearly described stage sequence that works with your machine and material, then keep each stage separate.
Before you choose
- Identify the abrasive or polish material, grade, and intended stage.
- Use the manufacturer’s dosing instructions for the exact tumbler.
- Keep coarse material and final-polish supplies clearly labelled.
- Compare the usable quantity and planned batches, not just bag count.
THE TRADEOFF THAT MATTERS
Buy for your process.
A longer sequence does not automatically fix unfinished shaping or contamination. Inspect the surface before advancing; fresh polish is not a substitute for correcting an earlier-stage problem.
