Bench Lathe Polisher with Flex Shaft | Jewelry Polishing and Grinding Machine
The SP-5006B is a 350W bench polisher with an integrated flexible shaft handpiece, designed for jewellers and metalcraft finishers who need both open-surface polishing and detailed inside work from a single compact machine.
A front-mounted dial provides stepless speed control from 0 to 10,000 RPM. Use the bench spindle area for accessible surfaces and edges, or switch to the flexible shaft and handpiece for rings, grooves, and recessed details. The 180 × 125 × 148 mm footprint fits small studios and repair benches.

Pro Tips
- Start at low speed and increase gradually after confirming the accessory runs smoothly and concentrically.
- Use light, controlled pressure — excess force reduces control and can overheat the workpiece or accessory.
- Progress from coarser to finer abrasives rather than trying to complete every stage with one wheel or compound.
- Keep the flexible shaft in a broad, relaxed curve during operation — avoid tight bends that stress the cable.
- Disconnect power before changing accessories, cleaning the spindle area, or inspecting the carbon brushes.
FAQ
Can I use the bench spindle and flexible shaft at the same time?
The machine provides both working formats, but only use the active setup needed for the task and keep clear of all rotating components.
Is this available in 110V?
No. The SP-5006B is available in 220V only. Confirm your workshop power supply is compatible before ordering — connecting to the wrong voltage will damage the machine.
What accessory sizes fit the handpiece and chuck group?
The flexible shaft handpiece accepts accessories with shanks from 0.3 to 4 mm. The separate chuck group accepts 0.6 to 6 mm shanks.
Are polishing wheels and compounds included?
Task-specific polishing wheels, grinding bits, abrasives, and compounds are not confirmed as included. Select consumables based on your material and required finish.
Is it suitable for heavy industrial grinding?
No. The SP-5006B is designed for jewellery, repair, and small metalcraft finishing — not for large workpieces or heavy continuous grinding.
