Frequently Asked Questions (FAQs)

1. What can be used as tumbling media?

Plastic has traditionally been used as the filler for rock tumbling, but ceramic seems to be preferred these days. Plastic can come in many types but we recommend and sell polypropylene plastic pellets because they are tough and will last longer than other types of plastic like polyethylene.

2. What is ceramic tumbling media used for?

Ceramic media works best for polishing, deburring, and even extreme metal removal. It's also more useful than plastic in heavy cutting and hard metal applications. If you require a very small media ceramic is your best option.

3. What is tumbling media made of?

Tumbling media is a blend of abrasives and binders. Ceramic Media is generally a clay or porcelain binder while Plastic Media and Synthetic Media are typically made from urea formaldehyde or polyester polymers. These binders are used to hold (bond) and shape the abrasive grit blend needed for a particular media type.
