Tumbler Barrels & Kits

We carry a wide range of rotary barreling machines for jeweller and metal polishing, as well as stone polishing. You can find all our kits and motors here.

Tumble finishing, also known as tumbling or rumbling, rotary finishing, barreling, or barrel finishing, is a technique for smoothing and polishing a rough surface on relatively small metal shapes and jewellery.

The easiest way to finish your metal clay (which requires minimal elbow grease), is to use a tumbler with mixed shape steel shot, water and a burnishing liquid or powder. Just brush your pieces quickly after firing, pop them in, and tumble for anything between 30 minutes to 6 hours, depending on your tumbler. Check your pieces every 30 minutes or so to see if you have reached the shine you are after. Done. Couldn't be easier!
