Tooltos DM-7 Bench Polishing Machine | 200W, 0-8000RPM Variable Speed
- 98 in stock
Description
The compact bench polishing machine for jewelers and watchmakers who need variable speed and dual-wheel capability in a small footprint — a continuously adjustable 0–8000RPM dial lets you match speed precisely to each wheel and material, dual left and right spindles let you run two wheel types simultaneously, and the 200W low-noise motor fits permanently on a standard jewelry bench at just 2.7kg.
Key Selling Points
- 0-8000RPM variable speed with continuous adjustment — dial in the exact speed for each polishing wheel type and workpiece material without fixed speed steps
- Dual left and right spindles accept polishing wheels with different inner hole sizes — run two different wheel types simultaneously or switch between them without reconfiguring the machine
- 200W motor with low noise design — suitable for studio environments where extended polishing sessions are common
- Compact at 190 x 120 x 145mm and 2.7kg — lighter and smaller than most bench polishers, fits on a standard jewelry bench without a dedicated equipment station
- Compatible with polishing wheels of varying inner hole sizes — use the appropriate wheel and polishing compound for each material and finish requirement
- Available in 110V and 220V to match your workshop power supply
About This Machine
Polishing quality depends on matching the right wheel speed to the material and the polishing compound. Too fast and the compound burns or the wheel skips across the surface. Too slow and the compound does not cut effectively, leaving a dull finish that requires more passes. Fixed-speed bench polishers force you to work around the machine's speed rather than setting the speed for the task. The Tooltos DM-7 eliminates this constraint with a 0-8000RPM variable speed dial that lets you set the exact speed for each wheel and material combination.
The dual spindle design lets you mount two different polishing wheels at the same time — a cutting compound wheel on one side and a finishing wheel on the other, for example — so you can move between polishing stages without stopping to change wheels. At 2.7kg and 190 x 120 x 145mm, the DM-7 is compact enough to sit permanently on the bench without taking up significant space.

Best For / Not For
| Best For | Not For |
|---|---|
| Jewelers and goldsmiths needing variable speed bench polishing for different metals and wheel types | Polishing wheels and compounds not included — must be sourced separately before use |
| Watch repair technicians and eyewear workshops needing a compact, low-noise polishing station | Heavy grinding or cutting operations requiring motors above 200W |
| Studios needing dual-wheel setup for multi-stage polishing without stopping to change wheels | Flex shaft or handpiece work — this machine has spindles only, no flex shaft or chuck attachment |
| Workshops with limited bench space needing a lightweight, compact polishing machine | Musical instrument and model making polishing — verify wheel compatibility with your specific workpiece geometry |

Pro Tips
- Start at a lower speed and increase gradually — the variable speed dial lets you find the optimal speed for each wheel and compound combination without committing to maximum RPM from the start.
- Mount a cutting compound wheel on one spindle and a finishing wheel on the other — this lets you move between polishing stages in a single session without stopping to change wheels.
- Apply polishing compound to the wheel while it is spinning at low speed, then increase to working speed — this distributes the compound evenly across the wheel surface before contact with the workpiece.
- Use lower speeds for softer materials (plastic, acrylic, coated surfaces) to prevent heat buildup that can melt or distort the workpiece surface.
- Keep the workpiece moving across the wheel rather than holding it in one spot — stationary contact concentrates heat and can cause uneven polishing or surface damage.
Frequently Asked Questions
Are polishing wheels included?
No. Polishing wheels and polishing compounds are not included and must be sourced separately. Select wheels with an inner hole size compatible with the DM-7 spindles and appropriate for your workpiece material.
Can this machine be used for grinding as well as polishing?
The DM-7 is primarily designed for polishing and buffing with polishing wheels. Light grinding is possible with appropriate grinding wheels, but for heavy grinding or cutting operations, a higher-power machine is recommended.
Does this machine have a flex shaft or handpiece attachment?
No. The DM-7 has left and right spindles only. It does not include a flex shaft or chuck group for handpiece work. If you need flex shaft capability combined with bench polishing, see the Tooltos Bench Lathe which includes both spindles and a flexible shaft handpiece.
Which voltage should I order — 110V or 220V?
Select the voltage that matches your workshop power supply. North America and most of the Americas use 110V. Europe, Asia, Australia, and most other regions use 220V.
What inner hole sizes do the spindles accept?
The DM-7 spindles accept polishing wheels with varying inner hole sizes. Verify the inner hole diameter of your polishing wheels before ordering to ensure compatibility with the spindle diameter.
