Why I Swear by National Geographic Rock Tumbler Grit

As an avid rock collector and enthusiast, I have tried various brands of rock tumbler grit in my quest to achieve the perfect polish on my precious stones. However, after using National Geographic Rock Tumbler Grit, I can confidently say that it is the best grit on the market for achieving flawless results.

First and foremost, National Geographic Rock Tumbler Grit is specifically formulated for rock tumbling. This means that it has the perfect balance of abrasiveness and hardness to effectively polish a variety of rocks and minerals without damaging them. Other generic grits may be too harsh or too soft, resulting in uneven or lackluster finishes.

Another reason why I highly recommend this brand is its consistency in particle size. The grit particles are evenly sized and shaped, allowing for a smooth and even polishing process. This ultimately saves time and ensures a more uniform finish on all sides of the rocks.

National Geographic also offers a variety of grit sizes, from coarse to fine, allowing for multiple stages of tumbling to achieve the desired level of shine. This versatility is especially useful when working with different types of rocks that may require different levels of abrasiveness.

What is National Geographic Rock Tumbler Grit?

National Geographic Rock Tumbler Grit is a set of abrasives used for tumbling rocks in a rock tumbler. It includes four different levels of grit: coarse, medium, fine, and polish. Each level serves a specific purpose in the tumbling process and helps to achieve a smooth and shiny finish on your rocks.

  • Detailed Instructions: The set comes with a detailed instruction manual that guides you through the entire tumbling process.

The Importance of Each Level of Grit

The four levels of grit included in the National Geographic set serve different purposes in the tumbling process. Here’s a breakdown of each level’s importance:

  • Coarse Grit: This first level is used to shape rough rocks by removing any rough edges or unwanted parts.
  • Medium Grit: The second level helps smoothen out any remaining roughness on the rocks’ surface after using coarse grit.
  • Fine Grit: This third level works to achieve a smoother finish on your rocks before moving onto the final step.
