What reviewers say
Tumble-Bee 2 x 2lb rock tumbler
Owners of Tumble-Bee rotary tumblers generally report steady, reliable running and quieter operation than plastic-barrel machines. The two-barrel layout is the main draw, letting people compare grits or materials in one session.
- Quiet running compared with many plastic-barrel tumblers
- Durable rubber barrels and lids that seal well
- Two barrels make grit-stage comparisons easy
- Motor holds up over multi-week tumbling cycles
- Small 2 lb capacity limits larger stones
- Belts and bearings wear and need occasional replacement
- Long run times before results show
Thumler's Model B Rotary Tumbler
Owners treat the Model B as a workhorse that lasts years, especially reloaders polishing brass and rockhounds running rough grinds. The common complaint is that the fast motor suits coarse work better than final polishing.
Questions and answers
- Which is better for polishing rocks at home?
- The Tumble-Bee 2x2. Its rotary speed suits the full grit sequence, and two barrels let you keep a batch moving through stages. The Model B is better as a rough grinder because 3000 RPM is fast for finishing.
- Which handles bigger batches?
- The Thumler's Model B. Its 15 lb barrel holds far more than the Tumble-Bee's two 2 lb barrels combined.
- Can the Thumler's Model B polish brass cases?
- Yes. It is widely used by reloaders with corn cob, walnut shell or stainless steel pins, and the 15 lb barrel suits bulk case cleaning.
- Is the Tumble-Bee good for kids?
- It is a common family and classroom pick, but it is a powered machine with a 115 V plug, so younger children need adult supervision.
- Which lasts longer?
- The Model B is built for continuous duty and carries a 5 year barrel and liner guarantee plus a 1 year parts and labor warranty. The Tumble-Bee is a hobby tumbler with no stated warranty.
- Is the Model B worth the extra money?
- Only if you need capacity or continuous running. For small batches of stones or glass, the Tumble-Bee does the job for far less.
