Tips for Cutting Granite with a Circular Saw:

It’s important to be mindful of safety when using a circular saw for cutting granite. Here are some things to keep in mind while you’re working:

Inspect Your Blade Before Use:

Before cutting granite, make sure you inspect your blade! A dull blade is more likely to shatter while cutting the granite.

Use High Speed on Your Cutter:

While cutting with your diamond-coated cutter, make sure that it’s on high speed. This will help you cut things faster and will result in cleaner cuts.

Start Slow Before Getting Into a Rhythm:

When making your first two or three passes on the granite, start slow instead of full speed. This will save you from chipping the granite and save your blade from overheating.

Keep a Water Source Nearby:

Keeping a water source nearby while cutting granite is a good idea since it helps keep the dust down and cool down your saw blade. If you do get any chips in your granite while cutting, make sure to pick them out with a chip brush.


Is it possible to cut granite with a circular saw?

Yes, but not every type of circular saw is capable.

What can I use instead of wet/dry vacuum cleaner?

You could also use a dust mask to remove smaller particles from the air so you can see what you are doing more easily. If this isn’t an option, simply try blowing your cuts clean with compressed air or another lawn blower. Make sure that ventilation is working well in the room where you are working if you do this step since breathing in too much granite dust can be harmful to your lungs over time.

What should I do if I hit a wire or pipe during the cutting process?

If you are using a wet/dry vacuum, disconnect it immediately and follow proper ventilation guidelines to protect your lungs before proceeding with the cut line. If you are using compressed air, refer to your owner’s manual for more information on how much pressure is too much. Make sure that all electrical lines are marked so you don’t accidentally cut any while working.
