Key Selling Points
- Hang-up motor suspends the 180W motor above the work area — the handpiece weighs almost nothing in your hand, allowing pencil-grip control for extended engraving, carving, and polishing sessions without fatigue
- 18000RPM full copper motor delivers consistent power for cutting, grinding, polishing, and texturing across metal, stone, wood, and jewelry materials
- 100cm (39.4 in) rubberized flexible shaft provides reach and flexibility to work at any angle without repositioning the motor
- High-precision 3-jaw chuck accepts bits from 4-6mm — compatible with a wide range of burrs, grinding stones, polishing wheels, and drill bits
- ABS foot pedal with adjustable constant-speed screw controls motor speed hands-free — both hands stay on the workpiece while the foot manages power
- Heat dissipation holes in the motor housing prevent overheating during extended use and extend motor service life
About This Flex Shaft Motor
Precision work on jewelry — engraving fine detail, carving wax models, grinding inside ring shanks, polishing recessed areas — requires a tool you can control with the same precision as a pencil. A standard handheld rotary tool puts the full weight of the motor in your hand, which causes fatigue within minutes and makes fine control difficult. The longer you work, the less precise your movements become.
The Tooltos Flex Shaft Motor solves this by hanging the motor from a hook above the bench. The 100cm flexible shaft transmits power from the suspended motor to the lightweight handpiece in your hand. You hold only the handpiece — which weighs almost nothing — while the motor hangs above. The result is a tool you can hold and maneuver like a pen, with the full 180W of motor power available through the shaft. The ABS foot pedal puts speed control under your foot, so both hands remain on the work at all times.
Common Applications
| Task | Attachment Type | Material |
|---|---|---|
| Engraving and carving detail | Carbide or HSS burrs | Gold, silver, brass, wax |
| Grinding and shaping | Grinding stones, abrasive wheels | Metal, stone, agate, jade |
| Polishing recessed areas | Felt bobs, polishing wheels | Jewelry settings, ring interiors |
| Adding texture | Texture burrs, wire brushes | Metal sheet and castings |
| Drilling small holes | Twist drill bits (4-6mm shank) | Metal, wood, stone |
Best For / Not For
| Best For | Not For |
|---|---|
| Jewelers and engravers who need precise, fatigue-free control for extended detail work sessions | Bits with shank diameter outside the 4-6mm chuck range — verify your bit shank size before ordering |
| Wax carvers who need a lightweight handpiece for detailed model work without motor weight in the hand | Heavy-duty cutting or grinding requiring torque above 180W — this is a precision jewelry tool, not an industrial grinder |
| Stone carvers and lapidary workers needing flexible reach for grinding and shaping agate, jade, and stone | Cordless or portable use — this tool requires a mains power connection and a hanging point above the bench |
| Workshops needing hands-free speed control via foot pedal during precision carving and engraving | Burrs, grinding stones, and polishing attachments not included — must be sourced separately |

Pro Tips
- Hang the motor at a height that allows the flexible shaft to hang in a gentle curve rather than a sharp bend — sharp bends in the shaft increase wear and reduce power transmission efficiency.
- Use the constant-speed screw on the foot pedal to set a baseline speed for repetitive tasks — this lets you maintain a consistent speed without holding the pedal at a precise position throughout the session.
- Hold the handpiece like a pencil rather than gripping it tightly — a light grip reduces hand fatigue and gives you better tactile feedback from the cutting action.
- Let the tool do the cutting rather than applying pressure — excessive pressure on burrs and grinding stones causes them to wear unevenly and can stall the motor at lower speed settings.
- Keep the flexible shaft clean and lightly lubricated at the connection points — a dry or dirty shaft connection increases friction, reduces power transmission, and shortens shaft life.
Frequently Asked Questions
Does this machine come with a hanging stand or arm?
No. The motor requires a hanging point above the bench — a hook, arm, or dedicated flex shaft stand — which is not included. Most jewelers hang the motor from a hook screwed into the underside of a shelf or from a dedicated flex shaft stand mounted to the bench.
What bit shank sizes does the chuck accept?
The 3-jaw chuck accepts bits with shank diameters from 4mm to 6mm. This covers most standard jewelry burrs, grinding stones, and polishing attachments. Verify your bit shank diameter before ordering accessories.
What voltage does this machine use?
The machine supports both 110V and 220V. This is a single-variant product — the unit automatically adapts to your local power supply within the 110V-220V range. Verify compatibility with your local voltage before use.
Are burrs and polishing attachments included?
No. Burrs, grinding stones, polishing wheels, and other attachments are not included and must be sourced separately. Select attachments appropriate for your material and task.
How does the foot pedal speed control work?
The ABS foot pedal controls motor speed by varying the power delivered to the motor. Press further to increase speed, release to decrease. The adjustable constant-speed screw on the pedal lets you set a fixed minimum speed so the motor maintains a baseline RPM without continuous foot pressure.
