Each tumbler is designed to deliver consistent, high-quality results for both beginners and experienced rock collectors.
- All-in-One Tumbling Solution: This complete 6 lb grit kit includes everything needed for a full 4-step rock tumbling process. Each set contains 2 lb of Step 1 (60-grit coarse silicon carbide), 2 lb of Step 2 (150-grit medium silicon carbide), 1 lb of Step 3 (600-grit fine silicon carbide), 1 lb of Step 4 (1200-grit aluminum oxide polish).
- Professional-Grade Results for Every Level: Designed to deliver consistent, high-quality finishes from rough shaping to final polishing. Whether you’re a beginner or an experienced lapidarist, this kit ensures a flawless transition through each stage for glossy, professional-grade stones.
- High Efficiency – Polish up to 40 lbs of Rocks: Each set provides enough grit and media to process up to 40 lbs of stones across multiple batches. Ideal for continuous projects or large-capacity tumblers, ensuring cost-effective and efficient tumbling sessions.
- Recommended Usage – For optimal results, use about 2 tablespoons (≈25–30 g) of grit per 1 lb of stones in each stage. Add just enough water to cover the stones inside the barrel and tumble for 7–10 days per step, checking periodically and adding water if needed to maintain smooth rotation. Adjust tumbling time slightly depending on stone hardness and size.
- Compatible with All Rock Tumblers: Suitable for both rotary and vibratory tumblers. Perfect for hobbyists, classrooms, and professional workshops alike—KoolStone grit kits are engineered to help you transform rough rocks into smooth, glass-like gems with ease and precision.
