Tooltos KT-1320 Double Drum Rotary Tumbler | 10kg, 4-Speed, 250W

Key Selling Points

• Two independent 5kg polycarbonate drums let you polish two different materials or media types simultaneously — run one drum with steel balls for burnishing while the other runs with a different compound for a separate batch
• 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 construction with tight-seal buckle closure — no spills during wet tumbling with water and burnishing compound
• Wear-resistant rubber base pads provide non-slip, shock-absorbing support during operation — reduces vibration transfer to the bench

About This Tumbler

Hand polishing a batch of cast jewelry pieces is one of the most time-consuming tasks in a production workflow. Each piece requires individual attention, consistent pressure, and repeated passes with progressively finer abrasives — work that takes hours when done by hand and produces inconsistent results across the batch. The Tooltos KT-1320 Double Drum Rotary Tumbler replaces this process with automated tumbling: load the drum with pieces and polishing media, set the speed and timer, and let the centrifugal action work the entire batch simultaneously while you focus on other tasks.

The dual drum design adds a further efficiency advantage — both 5kg drums operate independently, so you can run two different batches at the same time, or use one drum for a coarser cut and the other for final burnishing without waiting for the first cycle to finish. The 4-speed bidirectional control and 60-minute timer give you enough flexibility to dial in the right parameters for different metals and surface requirements.

Pro Tips

• Fill each drum no more than two-thirds full with pieces and media combined — overfilling reduces the tumbling action and produces uneven results across the batch.
• 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 for the material.
• 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.

Can I run both drums at the same time with different materials?
Yes. The two drums operate independently, so you can load each drum with a different batch or different media type and run both simultaneously. This is one of the key advantages of the dual drum design for production workflows.

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.
