Why National Geographic Rock Tumbler Grit is Necessary
When I first started my rock tumbling journey, I quickly realized that having the right materials was crucial for achieving the polished stones I envisioned. The National Geographic Rock Tumbler Grit, in particular, became an essential part of my process. I learned that grit isn’t just a random accessory; it’s the backbone of successful tumbling.
Using the right grit at each stage of the tumbling process helps to effectively shape and polish the stones. I remember my first few batches where I used subpar grit; the results were lackluster and disappointing. The National Geographic grit, however, is specifically formulated for optimal cutting and polishing. Each type of grit—coarse, medium, and fine—serves a distinct purpose that guides the rocks through their transformation. This systematic approach not only enhances the quality of the finished stones but also saves time and effort in the long run.
Moreover, I found that using a high-quality grit like National Geographic’s significantly reduces the risk of damaging my stones. Cheaper alternatives often led to uneven surfaces and chips, which was frustrating. With the right grit, I could see a clear progression in the appearance of my stones, which motivated me to keep going

After experimenting with various brands and types, I found that National Geographic Rock Tumbler Grit stands out for several reasons. Here’s my comprehensive buying guide based on my experience with this product.
Understanding Rock Tumbler Grit
Before diving into my recommendations, let’s talk about what rock tumbler grit actually is. Grit is a mixture of abrasives used to polish stones and minerals. The process typically involves multiple stages, each requiring different grit sizes to achieve the desired shine. I learned that using the right grit at each stage can significantly affect the outcome of my tumbling project.
Why Choose National Geographic Rock Tumbler Grit?
From my experience, National Geographic offers a high-quality grit that is designed specifically for their tumblers but can work well with others too. Here are a few reasons why I recommend it:
- Quality Assurance: The grit is manufactured to strict quality standards, ensuring consistent results.
- Ease of Use: The packaging is user-friendly, making it easy for me to measure out the right amount for my tumbler.
- Comprehensive Kits: National Geographic provides complete grit kits that include coarse, medium, fine, and polishing grits, which I found very convenient.
Types of Grit Available
I discovered that National Geographic offers different types of grit for various stages of the tumbling process:
- Coarse Grit (60/90): This is the first step in the tumbling process, perfect for shaping and smoothing rough stones. I noticed a significant difference in the stones after using this grit.
- Medium Grit (120/220): The medium grit refines the stones further, eliminating scratches left by the coarse grit. I appreciated how smooth my stones felt after this stage.
- Fine Grit (500): At this stage, I could see my stones starting to shine. The fine grit helped to polish the surface and prepare for the final stage.
- Polishing Grit (Pre-polish and Polish): This is where the magic happens! I was amazed at how shiny and beautiful my stones became after using the polishing grit.
How to Use National Geographic Rock Tumbler Grit
Using the grit is a straightforward process, but I’ve learned some tips along the way:
- Follow the Instructions: Always adhere to the instructions provided with the grit. I found that the recommended amounts and timing made a huge difference in the quality of the polish.
- Clean Your Tumbler: After each stage, I made sure to clean my tumbler thoroughly before moving on to the next grit. This helped prevent cross-contamination and ensured the best results.
- Be Patient: Tumbling rocks takes time. I learned to enjoy the process and not rush it, as each stage contributes to the final outcome.
