Description

The Arbe KMT-20 110V is a small size (125mm-5″ diameter) variable speed magnetic tumbler with a 30 ring capacity.  The KMT-20 is a powerful, professional grade magnetic tumbler perfect for the small shop and built for heavy duty use.

Magnetic tumbling has revolutionized the art of jewelry polishing, cutting hours of expensive hand labor from the process. Magnetic tumblers can polish to a bright finish the undersides of rings, undercuts, channels, fine filigree and other hard to reach places in as little as 30 minutes for gold and 45 minutes for platinum.

This is the new Arbe Super Mini Magnetic Tumbler.  Arbe is proud to introduce its line of super mini professional magnetic tumblers.  This new line has a small footprint but do big things.  A heavy duty motor provides robust power while the faceted bowl maximizes rotational action. 

This magnetic tumbler has variable speed control.  This allows you to set a precise speed for the job at hand. Single speed units only work at full power causing unwanted contact between your pieces.  You don’t want your pieces banging together as that can cause dents and scratches.  Variable speed control allows you to set your speed so that the pins are rotating around the pieces while the pieces move gently and not violently around the bowl.
Capacity: 30 Rings

Outside Dimensions Bowl Size: 5″ Diameter x 4″ Height (125 mm x 100 mm)

The perfect low cost magnetic polisher for someone who only needs to polish up to 30 small rings at a time. Magnetic tumblers are not just for rings.  Ring capacity is just the standard metric for measuring capacity. Uses tiny stainless steel magnetic pins with a solution of polishing soap & water to produce a beautiful bright shine on your work in as little as 30 minutes.

How does it work?

Imagine thousands of smooth tiny hammers pounding the surface of your jewelry. These hammers are burnishing the surface, just like if you took a polished steel burnisher and rubbed in against the surface. These tiny hammers can reach into the smallest crevices and channels, easily reaching places that you take a long time to finish by hand. The result is that the surface becomes bright, shiny and work-harden. For these hard to reach places, the polishing is complete. The smooth broad surfaces of your jewelry are now ready for a final quick polish by hand or in polishing media. All this is done much more quickly than what you could do in conventional rotary or vibratory tumblers. With magnetic tumbling there is no metal loss because magnetic tumbling is not an abrasive process.
