FAQs
Can I cut granite with a circular saw?
Yes, cutting granite with a circular saw is possible, but it requires caution and the right equipment. Granite is a very hard natural stone, so using a standard wood-cutting blade will lead to chipping, overheating, and rapid blade wear. To safely cut granite:
-
Use a diamond-tipped or segmented blade specifically designed for stone.
-
Wear safety gear—eye protection, gloves, and a dust mask are essential.
-
Keep the blade wet whenever possible; using a wet cutting method reduces dust, keeps the blade cool, and prevents cracks in the granite.
-
Clamp the granite securely to prevent movement during the cut.
-
Cut slowly and steadily, letting the blade do the work without forcing it through the material.
By following these precautions, a circular saw can be an effective tool for both professional and home projects.
What cutting disc for granite?
The ideal cutting disc for granite is a diamond blade, available in segmented, continuous rim, or turbo designs:
-
Segmented diamond blades: Great for rough cuts and fast material removal. They handle large slabs efficiently but may leave slightly rough edges.
-
Continuous rim blades: Provide smoother cuts, ideal for polished granite surfaces and detailed work.
-
Turbo blades: Combine speed and smoothness, suitable for thicker slabs while maintaining edge quality.
Choose a blade rated for wet cutting, as dry cutting generates excessive dust and heat. Blade diameter should match your saw specifications, with 6.5 inches being a common choice for portable circular saws.
What circular saw blade is used for countertops?
For granite countertops, professionals typically use a large-diameter diamond-tipped circular saw blade, often 7–10 inches depending on the saw. These blades are designed to:
-
Cut through dense stone without cracking edges.
-
Reduce vibration for a cleaner finish.
-
Be compatible with wet cutting to prolong blade life and reduce dust.
Pairing this blade with a stable guide or track system ensures straight cuts and precise countertop dimensions.
What is the best technique for cutting granite?
Effective cutting of granite requires a combination of the right blade, proper setup, and careful technique:
-
Mark your cut line clearly with a pencil or chalk.
-
Score the granite first by running the saw lightly along the line; this helps prevent chips.
-
Cut slowly at a consistent speed, avoiding forcing the blade.
-
Use water to keep the blade cool and reduce dust.
-
Finish edges carefully, sanding if necessary, to smooth any minor chips.
Always prioritize safety. Cutting in a controlled environment with proper clamping and dust control ensures the best results.
Final Thoughts
Choosing the best circular saw blade for cutting granite is critical for precision and safety. Diamond blades—whether segmented, continuous rim, or turbo—offer durability and clean cuts suitable for countertops and slabs. Pairing the right blade with proper technique, safety measures, and possibly wet cutting makes granite projects manageable even for DIY enthusiasts. With the right tools, achieving professional-quality cuts has never been easier.
