My Buying Guide on National Geographic Rock Tumbler Refill

As an avid rock collector and user of the National Geographic Rock Tumbler, I have gone through multiple refills in the past few years. Through my experience, I have learned what to look for when purchasing a refill for my tumbler. Here is my buying guide on the National Geographic Rock Tumbler Refill.

Compatibility with National Geographic Rock Tumbler

The first thing to consider is whether the refill is compatible with the National Geographic Rock Tumbler. This tumbler has a unique barrel size and shape, so not all refills will fit. Make sure to check the product description or packaging to ensure it is specifically designed for the National Geographic Rock Tumbler.

Type of Grit

There are different types of grit that come in a refill kit: coarse, medium, fine, and polish. Coarse grit is used for initial shaping of rough rocks, while medium grit smooths out scratches left by the coarse grit. Fine grit further smooths and polishes the rocks, and polish gives them a shiny finish. Before purchasing a refill kit, make sure it has all four types of grit included.

Amount of Grit Included

The amount of grit included in a refill kit varies from brand to brand. Some kits may only include enough for one batch of rocks, while others may have enough for multiple batches. Keep in mind how often you use your tumbler and how many rocks you typically tumble at once when considering the amount of grit included in a refill kit.

Quality of Grit

The quality of grit can greatly affect the outcome of your tumbled rocks. Lower quality grit may not produce the desired smoothness and shine, and may even cause scratches on your rocks. Look for refill kits that use high-quality, industrial-grade grit for best results.

Additional Supplies Included

Some refill kits may come with additional supplies such as extra barrels, tumbling pellets, or jewelry fastenings. These can be a great value and save you from having to purchase these items separately. Consider what supplies you may need in addition to the grit before making a purchase.

Price and Value

Last but not least, consider the price and value of the refill kit. While it may be tempting to go for the cheapest option, keep in mind that lower quality grit or fewer supplies included may affect the overall outcome of your tumbled rocks. Look for a refill kit that offers good value for its price and has all the necessary components for successful tumbling.

Overall, purchasing a National Geographic Rock Tumbler Refill can be a simple process if you keep these factors in mind. Remember to check compatibility with your tumbler, types and amount of grit included, quality of grit, additional supplies included, and price and value before making a decision. With these considerations in mind, you can continue tumbling beautiful rocks with your National Geographic Rock Tumbler!
