Arbe KMT-20/V Variable Speed 125mm Super Mini Mag Tumbler-110V

Arbe KMT-20/V Super Mini Magnetic Tumbler – Variable Speed 110V | 125mm (5") Bowl

The Arbe KMT-20/V Super Mini Magnetic Tumbler (110V) is a compact yet powerful professional-grade magnetic polisher designed for jewelers who need exceptional finishing results in a small-shop footprint. With a 30-ring capacity and variable speed control, this unit delivers precise, damage-free polishing for delicate jewelry pieces and intricate designs.

Magnetic tumbling has transformed jewelry finishing by eliminating hours of costly hand labor. The KMT-20/V can polish undercuts, channels, filigree, and hard-to-reach areas to a bright, burnished finish in as little as 30 minutes for gold and 45 minutes for platinum—areas that traditionally take extensive hand finishing.

This is the new Arbe Super Mini Magnetic Tumbler, built in the USA with heavy-duty construction for long-term shop use. A robust motor provides strong magnetic action, while the faceted bowl design maximizes pin rotation and polishing efficiency. Despite its compact size, this tumbler delivers results comparable to larger industrial units.

Unlike single-speed tumblers that run at full power and risk pieces banging together, the variable speed control allows you to fine-tune rotation speed. This ensures the magnetic pins circulate smoothly around your jewelry, gently moving the pieces while preventing dents, scratches, and surface damage.

Magnetic tumblers use tiny stainless steel magnetic pins, combined with water and polishing solution, to burnish metal surfaces without abrasion. Think of it as thousands of microscopic polished steel burnishers reaching deep into crevices and channels—producing a bright, work-hardened finish with zero metal loss.
