How To Cut Flagstone with Circular Saw?

Once you have gathered all the required tools and a suitable blade for cutting rock with a circular saw, you can move on to the main task. 

Here is the step-by-step process of cutting flagstones with a circular saw:

Get Yourself Prepared

Before you start working with your circular saw, make sure you wear your safety gear properly to get yourself ready for the job. Wear a pair of dust masks, earplugs, sturdy shoes, safety goggles, and heavy gloves. 

Measure the Cutting Piece

Start with measuring the width and height of the flagstone piece. This step is essential to decide what size saw blade you need for the task. Take your measure tap and write down the measurement on a piece of paper.

Make sure the measurements are accurate to prevent cracks or any unwanted situations in the future. 

Pick Your Saw Blade

You already know that a diamond-tipped saw blade is widely used to cut flagstones. But if you’re looking for a more affordable option, you can opt for standard masonry blades. 

These blades also cut effectively through heavy stones like limestone or granite. However, the tip of the blade should be fine and thin so that it can go through smoothly without cutting too much material.

Ensure Proper Lighting

Now, if you’re cutting the piece in your workshop, make sure the place is bright and has plenty of light. In case you’re cutting outdoors, try to complete the task during the daylight. 

Plus, ensure your work area has enough space to move around freely with the saw.

Mark the Stone

Before start cutting the flagstone piece, pre-mark the cutting lines to get precise and accurate results. Get your chalk or marker and accurately mark the backside of the stone.

However, you can skip this step if you’re cutting stones to decorate your garden ground or something similar. Stones with no specific curvings look better and more attractive for garden paths.

Cut

Great! Now that you’ve prepared your materials and have your marking in place, it’s time to start cutting. Here’s what you’ll need to do:

• Secure your cutting piece on a table or even surface. If you don’t have a cutting table, that’s okay – just make sure the flagstone is stable.
• Swap out the old blade for a new diamond blade and set it no deeper than an inch. Check out how to change the blade easily.
• Sit on a low stool and hold the saw with both hands.
• Slowly start cutting along your marking, pulling the saw towards you. You can gradually increase the speed as you go.
• If you’re cutting scrap pieces of flagstone to create a new tile, be extra careful as it can be prone to cracking.
• Once you’re finished, turn off the saw and store it safely. Wipe off any excess dust from the new cutting piece and place it where you’d like.

And there you have it! You’re all set with your freshly cut flagstone.
