How does a 15 lb tumbler compare with a 3 lb one?

It holds roughly five times the load, so you can polish a real batch instead of a handful of stones. The trade-off is more weight, more space and longer to fill and empty.

Can it polish sea glass and brass too?

Yes. The maker lists sea glass, antique bottles, brass, rocks, grinding and mixing as uses, so it is not limited to stones.

The sealed rubber barrel and PVC body are designed to keep noise down, but any rotary tumbler runs for weeks at a time and will be audible in a quiet room.

What comes in the box?

The tumbler with its single barrel, plus one extra V-belt. Grit and polishing media are not listed, so plan to buy those separately.

Can I run two grit stages at once?

No. It has a single barrel, so each stage runs one batch at a time. Two barrels would be needed to run coarse and fine grits in parallel.

Our take on the 15 lb Rock Tumbler Machine Rock Polisher Kit

The NS SUPPLY CO 15 lb Rock Tumbler is a single-barrel rotary tumbler built around a large PVC barrel with a sealed rubber liner. A 120-volt fan-cooled motor drives the barrel through a V-belt, and a spare belt is included. The 15 lb capacity puts it well above the 3 lb hobby tumblers most beginners start with, so it suits people polishing batches of rocks, sea glass or brass rather than a handful of stones. The sealed rubber barrel is meant to cut running noise, though a tumbler this size still runs for weeks per batch and is not silent.
