As an avid rock collector and enthusiast, I have experimented with various methods to polish and enhance the beauty of my stones. However, it wasn’t until I used National Geographic Rock Tumbler Grit that I truly saw a significant difference in the results. Here’s why I believe this product is a necessity for any rock tumbler enthusiast.

Firstly, the grit provided by National Geographic is specifically designed for rock tumbling.

Moreover, National Geographic Rock Tumbler Grit comes in multiple stages, from coarse to fine. This allows for a gradual and thorough polishing process, resulting in a smoother and more polished finish compared to using just one type of grit. Each stage serves a specific purpose, with coarse grit removing rough edges and imperfections, medium grit smoothing out surfaces, and fine grit giving a final glossy shine.

Another reason why this product is necessary is its durability. The grit particles

My Buying Guide on ‘National Geographic Rock Tumbler Grit’

As an avid rock collector and enthusiast, I have been using the National Geographic Rock Tumbler for years now. It has never failed to provide me with beautifully polished and shiny rocks. However, one of the key components of this tumbler is the grit, which is responsible for smoothing and polishing the rough rocks. In this buying guide, I will share my personal experience and tips on choosing the best National Geographic Rock Tumbler Grit.

Understanding Grit

Before diving into the details of buying National Geographic Rock Tumbler Grit, it is crucial to understand what grit is and its role in rock tumbling. Grit is a substance made up of small particles that help in smoothing and polishing rough rocks by removing their imperfections. It comes in different forms such as silicon carbide, aluminum oxide, and cerium oxide.

Types of Grit

National Geographic offers three types of grit – coarse, medium, and fine. Each type has a specific purpose in the tumbling process. The coarse grit (60/90) is used to smooth out any rough edges or surfaces on your rocks. The medium grit (180/220) further smooths out the rocks while the fine grit (500/600) gives them a final polish.

Quantity

When purchasing National Geographic Rock Tumbler Grit, it is essential to consider how much you will need for your tumbling process. The amount of grit needed depends on the size and capacity of your tumbler as well as how many batches of rocks you plan on tumbling at once. As a general rule, you should use 1 tablespoon of each type of grit per pound of rocks.

Quality

The quality of your grit can significantly impact the results of your tumbled rocks. Low-quality grit may not effectively smooth out or polish your rocks, resulting in unsatisfactory results. It is crucial to purchase high-quality grit from reputable sources to ensure optimal tumbling outcomes.

Compatibility with National Geographic Tumbler

To achieve the best results with your National Geographic Rock Tumbler, it is recommended to use their brand-specific grit as it is specifically designed for their tumblers’ motors and barrels. However, if you choose to use other brands’ grits, make sure they are compatible with your tumbler’s motor power and barrel size.

Cost

The cost of National Geographic Rock Tumbler Grit may vary depending on where you purchase it from. It is essential to consider both quality and quantity when comparing prices between different retailers or online stores.

Final Thoughts

Overall, I highly recommend using National Geographic Rock Tumbler Grit for optimal results with your rock tumbling process. Remember to always follow instructions carefully when using any type of grit and be cautious when handling it as it can be harmful if ingested or inhaled. Happy tumbling!
