Description
Key Selling Points
- Stepless speed control from 0 to 8000RPM — dial in the exact speed for each material and task without being locked into fixed speed steps
- Two tapered spindles accept polishing wheels and brushes up to 5 inches (127mm) in diameter — both sides operate simultaneously for double the throughput
- Transparent acrylic safety baffle blocks polishing compound and debris from reaching your face while keeping the work area fully visible
- Pure copper motor delivers 200W of consistent power with low heat buildup — reliable for extended polishing sessions without performance drop
- Compact footprint (380 x 260 x 250mm / 15.0 x 10.2 x 9.8 in) and 5.8kg (12.8 lb) weight — fits on a standard jewelry bench without dominating the workspace
- Available in 110V and 220V to match your workshop power supply
About This Polishing Machine
Every material has an optimal polishing speed. Run too fast on soft gold or silver and the polishing compound burns into the surface, leaving discoloration that requires additional work to remove. Run too slow on harder metals and the wheel glazes over without cutting, wasting time and compound. Fixed-speed bench polishers force you to work at whatever speed the motor runs, regardless of what the material actually needs. The Tooltos DM-7 eliminates this constraint with a stepless speed controller that lets you set any speed from 0 to 8000RPM — slow for delicate finishing on soft metals, fast for aggressive cutting on harder materials, and anywhere in between for everything else.
The dual tapered spindles let you mount different wheels or brushes on each side — a cutting compound wheel on one side and a finishing wheel on the other, for example — so you can move between stages without stopping to change attachments. The transparent acrylic baffle keeps compound and debris away from your face without blocking your view of the work, which matters when you are doing detail polishing that requires close visual monitoring.
Speed Guide by Material
| Material | Recommended Speed Range | Notes |
|---|---|---|
| Gold, silver (soft metals) | Low to medium (1000-4000RPM) | Lower speed reduces heat and prevents compound burn-in on soft surfaces |
| Brass, copper, aluminum | Medium (3000-6000RPM) | Medium speed balances cutting efficiency and surface temperature |
| Agate, jade, hard stone | Medium to high (4000-7000RPM) | Higher speed needed for effective cutting on hard materials |
| Acrylic, plastic, dental materials | Low to medium (1000-4000RPM) | Low speed prevents heat distortion and melting on thermoplastic materials |
| Rust removal, deburring | High (6000-8000RPM) | Maximum speed for aggressive material removal with wire brush attachments |
Best For / Not For
| Best For | Not For |
|---|---|
| Jewelers and metalsmiths polishing gold, silver, brass, copper, and aluminum at variable speeds | Polishing wheels and brushes not included — must be sourced separately to match your material and finish requirements |
| Workshops needing two different wheel types mounted simultaneously for multi-stage polishing without attachment changes | Wheels larger than 5 inches (127mm) in diameter — the spindles accommodate up to 5 inch wheels only |
| Polishing agate, jade, acrylic, dental materials, and metal parts requiring different speed settings | Heavy industrial grinding requiring motors above 200W — this is a bench jeweler's polisher for precision finishing work |
| Jewelry stores and studios needing a compact, variable-speed bench polisher for daily finishing work | Wet polishing with water — this machine is designed for dry polishing with compound-loaded wheels and brushes |

Pro Tips
- Start at a low speed and increase gradually until you find the speed that produces the best result for your material — the stepless controller makes it easy to fine-tune without committing to a fixed setting.
- Mount a cutting compound wheel on one spindle and a finishing wheel on the other — this lets you move between cutting and finishing stages without stopping to change attachments, which significantly speeds up the polishing workflow.
- Apply polishing compound to the wheel while it is spinning at low speed, then increase to working speed — applying compound at high speed causes it to fling off the wheel before it can load properly.
- Keep the workpiece moving across the wheel surface rather than holding it in one spot — stationary contact concentrates heat and can burn the surface or create uneven polish marks.
- Clean the acrylic baffle regularly — compound buildup on the baffle reduces visibility and can drip onto the work surface during operation.
Frequently Asked Questions
Are polishing wheels included?
No. Polishing wheels and brushes are not included and must be sourced separately. Select wheels appropriate for your material and the finish you want to achieve. The spindles accept wheels up to 5 inches (127mm) in diameter.
Can both spindles run at the same time?
Yes. Both tapered spindles operate simultaneously at the same speed. You can mount different wheel types on each side and switch between them during the polishing process without stopping the machine.
What is the benefit of stepless speed control over fixed speeds?
Stepless control lets you set any speed between 0 and 8000RPM rather than choosing from a limited set of fixed steps. This matters because different materials and compounds have different optimal speeds — soft metals need lower speeds to avoid heat damage, while harder materials need higher speeds for effective cutting. Stepless control lets you match the speed precisely to the task.
What is the maximum wheel size this machine accepts?
The tapered spindles accept polishing wheels and brushes up to 5 inches (127mm) in diameter. Do not use wheels larger than this maximum.
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.
