110V / 120V supply only. This unit is built for standard North American household current (110V / 120V). Running it on 220V / 240V through a voltage converter-transformer voids any warranty the equipment may have. Confirm your outlet voltage before powering on.

A small rotary tumbler kit for burnishing jewelry, castings and small parts to a bright, work-hardened finish. The Thumler’s Tumbler Model A-R1 pairs the 110V A-R1 rotary tumbler with rust-resistant stainless steel mixed shot and Otto MF 610 concentrated burnishing compound. Built to run continuously, the A-R1 burnishes slowly and consistently, and it is made in the USA by Tru-Square Metal Products.
Features
Continuous-duty rotary action for uniform results
Molded rubber 3 lb barrel reduces noise and cushions parts
Burnish with steel shot or cut down with plastic or ceramic media
Also suitable for rock tumbling with silicon carbide and cerium oxide
Rust-resistant stainless shot is simpler to care for than plain carbon steel shot
Made in the USA
Compatibility
Burnishing: stainless steel shot with MF 610 compound brightens and work-hardens castings and fabricated parts.
Cut-down: plastic or ceramic media with detergent compounds give more aggressive surface refinement.
Lapidary: rock tumbling with silicon carbide for grinding and cerium oxide for polishing.
Notes
Do not exceed barrel capacity; the total load includes media, parts and liquid.
Rinse stainless shot after use and allow it to drain; stainless resists rust and is easier to maintain than plain steel shot.
Follow incremental grit stages and thorough cleanouts when cutting with plastic or ceramic media or rock tumbling abrasives.
