Hard stones like agate are actually softer than the diamond dust embedded in your saw blade. This simple reality allows a thin metal disc to slice through mineral deposits that have existed for millions of years.
Finding the Best Lapidary Saws depends on understanding your specific throughput needs. Some setups prioritize precision, while others value raw horsepower. Here is what you should consider before making your final selection.
Key Takeaways
- Prioritize a water cooling system to prevent your blade from overheating and warping during heavy usage.
- Ensure the arbor size matches your blade requirements exactly to avoid dangerous wobbling while the machine is running.
- Select a variable speed motor if you plan to switch between cutting soft cabochon materials and harder, crystalline specimens.
- Verify the cutting capacity or throat depth of the saw to confirm it can accommodate the size of your rock collection.
- Opt for thin kerf blades when working with expensive rough to minimize the amount of material lost as dust.
