About This Tumbler
The Tooltos KT-1320 Double Drum Rotary Tumbler replaces time-consuming hand polishing with automated tumbling. Load each drum with jewelry pieces and suitable polishing media, set the speed and timer, and let the centrifugal action work the batch while you focus on other tasks. The independent dual-drum design lets you run two batches or media types simultaneously.

Frequently Asked Questions
Is polishing media included?
No. Steel balls, iron beads, stainless steel pins and burnishing compound must be sourced separately.
Can both drums run simultaneously with different materials?
Yes. The independent drums can run different batches or media types at the same time.
What metals can it polish?
Jewelry, steel, iron, copper, zinc, aluminum and magnesium alloy materials.
Is it suitable for fragile settings?
Tumbling applies uniform force and may damage fragile prongs or settings. Use hand polishing for delicate pieces.
