Covington Machines - Triple 1/2 Gallon Tumbler - 110v
SKU:

Description:
The Triple 1/2 Gallon Tumbler is a stout, American-made rolling tumbler built as a powered base with three rotating barrel stations and removable tumbling barrels. It is designed for rotary tumbling where the load is carried and rolled continuously to grind, smooth, and polish hard materials over time. Covington’s design uses raised ridges inside each barrel to prevent the contents from sliding, which promotes a faster grind and more consistent abrasion. The rotary speed is factory preset to support effective abrasion and polishing action, and the barrels remove easily for inspection and cleaning. In glass and lapidary workflows, a tumbler like this is used when you want hands-off, batch processing for smoothing and pre-polishing small parts, such as tumbled stones for jewelry components, small glass pieces intended for coldworked finishes, or media-assisted edge softening on durable materials that tolerate tumbling. The unit ships complete with a belt guard, instructions, and a product guarantee.
How it is used:
- Load each barrel with the workpieces, the appropriate tumbling media, and enough water or compound to match the stage you are running.
- Seal the barrel securely, then place it on the rollers and confirm it rotates smoothly without wobble.
- Run the tumbler for the required time for the grit stage, checking periodically for progress and to confirm the load is not packing or stalling.
- When a stage is complete, remove the barrel, rinse the load thoroughly, and clean the barrel before moving to a finer grit or polish stage.
- After the final stage, rinse and dry the finished pieces, then clean the barrels so grit does not contaminate the next run.
