The HST 3# Rock Tumbler rivals more expensive rock polishers and brands, like Lortone models. Though comparable in quality and results, the HST Tumbler Kit crushes competitors in price. We work directly with the manufacturer to build this rock tumbler, ensuring that your tumbler meets HST's strict standards and satisfaction guarantee at a lower price.

Even beginner rock tumblers get professional results with the HST 3# Rock Tumbler. Affordable and easy-to-use, this rock polishing rotary tumbler features a rubber barrel and continuous-duty electric motor; the rubber tumbler barrel provides extra sound absorption for quieter operation.

Rotary tumblers, like the HST 3# Rock Tumbler, offer an advantage over vibratory tumblers: Over the 4-6 weeks it takes to polish a batch of rocks, this tumbler grinds rough edges off of rough rock, producing smooth rounded corners. It's also equal to the task of tumbling hard minerals.

Let the rock tumbling fun begin!
