Tooltos KT-1320 Single Drum Rotary Tumbler | 16kg, 4-Speed, 250W
- 97 in stock
Description
Key Selling Points
- 16kg single drum capacity — 60% more capacity than the dual-drum 10kg model, allowing larger batch sizes in a single cycle without splitting the load
- 330 x 230mm (13.0 x 9.1 in) drum with 155mm (6.1 in) opening accommodates larger individual pieces that do not fit in the 125mm opening of the dual-drum model
- 4-speed bidirectional rotation up to 200RPM — adjust speed and direction to match the material hardness and the surface finish required
- 0-60 minute timer lets you set the cycle and step away — the machine stops automatically when the timer expires
- 250W motor with centrifugal tumbling action improves work efficiency 5 to 10 times compared to hand polishing the same batch
- Leak-proof polycarbonate drum with tight-seal buckle closure and wear-resistant rubber base pads for stable, shock-absorbing operation
About This Tumbler
When a production run exceeds what a smaller tumbler can handle in a single cycle, the choice is either to split the batch across multiple loads or to use a machine with enough capacity to process the full batch at once. The Tooltos KT-1320 Single Drum Rotary Tumbler is built for the second approach: a 16kg polycarbonate drum that handles larger batches in one cycle, reducing the number of setups and the total time spent loading, unloading, and restarting between runs.
The 155mm (6.1 in) drum opening also accommodates larger individual pieces — bangles, cuff bracelets, and larger pendants that cannot fit through the 125mm opening of the dual-drum model. If your workflow involves running two different batches or media types simultaneously, the Tooltos KT-1320 Double Drum Tumbler (2 x 5kg drums) is the better choice. If you need maximum single-batch capacity or larger piece clearance, this 16kg single drum model is the right tool.
Choosing Between the Two KT-1320 Models
| Feature | Double Drum (10kg) | Single Drum (16kg) — This Model |
|---|---|---|
| Drums | 2 x 5kg (independent) | 1 x 16kg |
| Drum opening | 125mm (4.9 in) | 155mm (6.1 in) |
| Best for | Running two batches or media types simultaneously | Larger single batches, larger individual pieces |
| Choose if | You need flexibility to run different materials at the same time | You need maximum batch capacity or larger piece clearance |
Best For / Not For
| Best For | Not For |
|---|---|
| Production studios polishing large batches of cast gold, silver, brass, copper, and zinc alloy pieces in a single cycle | Polishing media not included — steel balls, iron beads, or burnishing compound must be sourced separately before use |
| Polishing larger individual pieces (bangles, cuffs, large pendants) that require the 155mm drum opening | Running two different batches or media types simultaneously — use the Double Drum model for that workflow |
| Surface finishing including burnishing, chamfering, deburring, rough finishing, and fine grinding across a range of metals | Delicate pieces with fragile settings or thin prongs — tumbling applies uniform force to all surfaces and can damage fragile structures |
| Removing black spots, surface oxidation, and casting skin from metal workpieces before final finishing | Polishing cycles longer than 60 minutes without manual restart — the timer maximum is 60 minutes per cycle |

Pro Tips
- Fill the drum no more than two-thirds full with pieces and media combined — overfilling reduces the tumbling action and produces uneven results across the batch, even in a large-capacity drum.
- Start at a lower speed setting for the first cycle with a new batch — higher speeds increase the impact force between pieces and media, which can cause surface damage on softer metals if the speed is too aggressive.
- Use bidirectional rotation for more uniform surface coverage — reversing direction periodically prevents pieces from nesting together and ensures all surfaces are exposed to the media.
- Separate pieces by size and weight before loading — mixing very small and very large pieces in the same drum can cause the larger pieces to damage the smaller ones during tumbling.
- Check the drum seal before each use — the buckle closure must be fully engaged to prevent leaks during wet tumbling with water and burnishing compound.
Frequently Asked Questions
Is polishing media included with the machine?
No. Polishing media (steel balls, iron beads, stainless steel pins, or burnishing compound) is not included and must be sourced separately. The type of media you use depends on the metal and the surface finish you want to achieve.
What is the difference between this model and the Double Drum 10kg model?
This model has a single 16kg drum with a 155mm (6.1 in) opening, giving you more capacity per cycle and the ability to load larger individual pieces. The Double Drum model has two independent 5kg drums with 125mm openings, allowing you to run two different batches or media types simultaneously. Choose this model for maximum batch capacity; choose the Double Drum for workflow flexibility.
What metals can this tumbler polish?
The KT-1320 is suitable for jewelry, steel, iron, copper, zinc, aluminum, and magnesium alloy materials. It handles surface polishing, chamfering, deburring, rough finishing, and fine grinding across this range of metals.
What is the maximum timer setting?
The timer maximum is 60 minutes per cycle. For polishing processes that require longer than 60 minutes, restart the timer manually at the end of each cycle until the desired finish is achieved.
Is this suitable for pieces with delicate settings or thin prongs?
Tumbling applies uniform mechanical force to all surfaces of every piece in the drum. Pieces with fragile prong settings, thin wire work, or delicate stone settings may be damaged during tumbling. Hand polishing is recommended for these pieces.
