The Lortone 33B is a dual-barrel rotary rock tumbler sold as a starter kit with a 4-step polish kit and rough rock. Two barrels let you run separate batches or keep one barrel dedicated to polishing while the other grinds. The barrels are molded from thick, wear-resistant rubber, which dampens some of the drumming noise and holds up to long runs. It suits hobbyists who want more capacity than a single-barrel tumbler without stepping up to a large professional unit.

Owners of the 33B describe it as a dependable dual-barrel workhorse that runs quietly for a rotary tumbler and holds up over many batches. Most praise the rubber barrels and the ability to run two loads at once; complaints center on run time and the noise of long overnight cycles.
The 33B Rock Tumbling Kit is a larger rock tumbler set from Lortone. It suits users who have several batches of stones to run, or who want to keep one barrel just for polishing.
The kit includes the durable 33B tumbler, the Lortone 4-Step polish kit, and rough rock to get started. The barrels are molded locally from resilient, wear-resistant rubber, which also absorbs extra sound.
