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

A magnetic tumbler burnishes finished jewelry at the bench, bringing a bright finish to the undersides of rings, undercuts, channels, and fine filigree that are slow to reach by hand.

The Arbe KMT-20/V Variable Speed 125mm Super Mini Magnetic Tumbler is a professional-grade, 110V magnetic tumbler designed for small shops and heavy-duty use. With a 5" (125 mm) diameter faceted bowl and a 30-ring capacity, this compact unit delivers serious polishing performance in a small footprint. A heavy-duty motor provides robust power, and the faceted bowl design maximizes rotational action throughout the tumbling cycle.

Magnetic tumbling has revolutionized jewelry polishing by cutting hours of hand labor from the finishing process, working in as little as 30 minutes for gold and 45 minutes for platinum. Because magnetic tumbling is a burnishing process rather than an abrasive one, there is no metal loss during operation.

The KMT-20/V features variable speed control, which sets it apart from single-speed units. Single-speed tumblers run at full power at all times, which can cause pieces to collide and result in dents or scratches. Variable speed allows you to dial in a precise operating speed so that the pins rotate around your pieces while the pieces move gently, not violently, through the bowl. This level of control is essential when working with delicate or detailed jewelry.

The process works by using thousands of tiny stainless steel magnetic pins that act like smooth, miniature burnishing tools, reaching into the smallest crevices, channels, and undercuts that would take considerable time to finish by hand. The result is a bright, shiny, work-hardened surface. Broad flat surfaces can then receive a final quick polish by hand or in conventional media. Magnetic tumbling is not exclusively for rings; ring capacity is simply the standard industry metric for measuring bowl capacity.
