Pro Tips for Cutting Ultra-Hard Stones

  1. Always Use Cooling: Wet cutting prevents overheating, reduces wear, and minimizes dust.
  2. Select the Right Blade: Match the diamond blade to the stone type for optimal performance.
  3. Use Steady Pressure: Let the tool do the work; excessive force can damage both the blade and the stone.
  4. Secure the Material: Stabilize the stone to avoid shifting and ensure clean cuts.
  5. Invest in Quality Tools: High-quality tools and blades ensure efficiency and long-term cost savings.

By choosing the right tools and following best practices, cutting ultra-hard stones becomes a more efficient and precise process.
