Replacement Rock Tumbler Barrel for National Geographic Tumblers, 2 Pound with Leak-Proof Lid

To ensure a flawless final polish when tumbling rocks, many professional enthusiasts opt to keep a dedicated barrel handy. It can be challenging to prevent any leftover grit from interfering with the polishing process when switching between shaping and polishing stages. With an extra barrel on hand, you can eliminate the risk of rougher grits damaging your gemstones during the final polish.

Our polishing barrel is a must-have tool for achieving professional-quality results. We recommend using a separate barrel solely for the last step of the polishing process to avoid any traces of coarser grit that could potentially scratch your gemstones and compromise the final finish.

Compatible with the National Geographic Professional Rock Tumbler, Hobby Series Tumbler, as well as the Discover with Dr. Cool Professional Rock Tumbler and Hobby Series Tumbler, this replacement part is a convenient and effective solution for upgrading your tumbling equipment.

Crafted from durable rubber with a leak-proof lid, this barrel is designed to operate quietly and with ease. Simply add your rocks, gemstones, petrified wood, sea glass, or any other materials you wish to polish, and let the barrel work its magic.

At Discover with Dr. Cool, customer satisfaction is our top priority. We stand behind the quality of our products and are dedicated to ensuring that you are completely satisfied with your purchase.
