Lortone 33B Rock Tumbler – Dual-Barrel Power in a Compact Design

Polish more stones with less hassle using the Lortone 33B Rock Tumbler, one of the most trusted tumblers in the lapidary world. With twin 3 lb. rubber barrels and an upgraded drive system, the 33B gives you increased capacity without taking up extra space. Whether you're tumbling agates, jasper, or beach glass, this dual-barrel setup lets you run two batches at once—perfect for experimenting with grit stages or separating stone types.

Built on a compact and durable steel base (just 6.25" x 10.25"), it’s a space-saver that delivers professional results. The quiet-running rubber barrels minimize noise and protect delicate stones as they tumble to a smooth, polished finish.

Ideal for beginners and experienced hobbyists alike, the 33B is your reliable workhorse for producing beautiful, high-quality stones.

Key Benefits:

  • Dual 3 lb. barrels let you tumble more at once—or run two different batches simultaneously

  • Heavy-duty upgraded motor for smoother operation and longer life

  • Compact footprint fits easily on workbenches or hobby tables

  • Quiet operation with long-lasting rubber barrels

  • Perfect for polishing a variety of rocks, minerals, and glass

I had a great experience working with Craig. I needed to change my order and they were already aware of my mistake with the saw size. Everything was so easy and smooth.

CabKing Grinder with attached saw

I have set up the grinding machine which was very easy. I have not used it yet but will be soon. I have taken it apart to set up the saw attachment which was also easy and have used that and am loving it.

We all look for our lapadary items and sometimes we find a new supplier. Not only do Gem stone labs have great prices they ship your items out very fast. They are reachable via chat or phone during normal hours. They are my new go to store for supplies. I have found the quality of products meets or exceeds my expectations.
