VEVOR Rock Tumbler Kit, 4 lb Belt-Free Rock Polisher, 4 Speeds

A 4 lb rock tumbler with a belt-free drive. There is no rubber belt to stretch, slip or replace, which is the part that usually fails first on a hobby tumbler. Four speed settings, a 9-day timer, built-in overload protection and an adapter included.

Double the barrel capacity of the 2 lb kit, so you can run a real batch of slabs and nodules rather than a handful. A full rough-to-polish cycle still takes roughly four weeks across the grit stages. Grit and rough are not included with this one — see the 2 lb kit if you want a batch to start with. Model KD-C3021. 7.0 x 9.1 x 8.3 in assembled, 7.72 lb. Ships from the US.
