Product description
This professional rock tumbler kit brings workshop stability and quieter operation to hobbyist polishing projects, ideal for serious collectors and adults who want repeatable results. The professional rock tumbler kit handles larger loads and longer runs while keeping noise low, and it includes everything needed to start polishing right away.
Key features
The kit pairs a brushless motor with a heavy metal base to reduce vibration and heat, delivering longer continuous operation and a steadier polish. The 4LB barrel is made from pneumatic grade rubber so runs stay quieter and more suited to indoor use, and the adjustable settings let you match speed to the grit and stage of the job. Included accessories cover the basics and the extras, so you can begin projects without sourcing parts elsewhere. 🧰
Tech specs
- Name: KomeStone Professional Rock Tumbler Kit
- Capacity: 4LB
- Motor: brushless motor rated 20,000-40,000 hours
- Control: 3 speeds, 9 day timer
- Base: heavy metal reinforced
Usage tips
Start with a coarser grit and longer cycles, then step down gradually to finer grits for a polished finish. For multi-day runs place the kit on a stable, level surface and use the memory and auto shutoff features to avoid overprocessing. Keep the rubber barrel and seals clean after each batch to reduce odors and extend component life. 🪨
What stands out
The combination of a brushless motor and a heavy iron base makes this unit run cooler and last longer compared to entry level models. Noise suppression of the rubber drum helps when operating indoors for several days, and the 9-day timer with memory supports unattended sequences according to manufacturer claims. A 90 day extended refund window and one year warranty are included by the seller, offering added reassurance for collectors trying more ambitious polishing projects. 🔧
