It reduces frequent repurchasing and lowers per‑polishing cost, ideal for continuous use with our A1, A1 Pro, and A3 rock tumblers.
- Dual Media for Smoother & Finer Finish: The rock tumbler grit and polish refill comes with 2 lbs of ceramic tumbler media and 1 lb of plastic pellets, which can be used in all polishing stages.Ceramic pellets protect stone surfaces and reduce noise, while plastic pellets help balance barrel weight for smoother tumbling, further improving smoothness and finish quality.
- Recommended Grit Dosage: We suggest 2 scoops of polishing grit per 1 lb of stones for each stage; use 4 scoops for 2 lbs of stones. Slightly increasing grit amount can improve polishing performance. Recommended rolling time per stage is 7–10 days, adjustable based on stone hardness and size.
