Tips to How cut flagstone with circular saw:

  1. Make a template. A circular saw cuts best when it is guided by a straightedge. To make a template, draw the outline of the flagstone on a piece of plywood or cardboard and cut it out with a jigsaw.
  2. Cut the flagstone along the template line using a circular saw. For best results, use a saw blade that is specifically designed for cutting stone.
  3. Wear safety gear. Safety goggles, gloves and earplugs are essential when using power tools.
  4. Drill pilot holes in the flagstones before using masonry screws to fasten them together. The screw should be long enough to go through the stone and about 1/4 inch into the base. To find out what size drill bit you need, measure the diameter of the screw shaft and divide by 2; that will give you your bit size.
  5. Keep in mind that when you are working with flagstone, the thickness of the material is not uniform, but it varies from one piece to another. That means there will be some stones that need to be sanded down a bit for a perfect fit.
  6. If necessary, sand each stone before setting them in place. To reduce the amount of dust created by sanding, cover the floor and furniture with drop cloths and move them out of the room or use a sander with a vacuum attachment.
  7. Use a rubber mallet to tap stones together. The circular saw method will make saw marks on each piece.

In either case, make sure to measure and mark your stone accurately before starting to cut.

Make sure to wear the appropriate safety gear and drill pilot holes in the stone before screwing them together. Remember that not all flagstone is uniform in thickness, so some stones may need to be sanded down for a perfect fit. Use a rubber mallet to tap the stones together, this will help reduce the number of saw marks on each piece.
