Many different tools can be used to cut stone, from chisels to expensive professional rock cutters. If you are working on a small rock, stone or masonry cutting project at home, you may not need to rent a rock cutting saw to finish the job. The simplest way to build a rock cutting saw is simply to convert an existing circular saw. With the right blade, a circular saw is capable of cutting even the strongest granite.

Step 1

Purchase an abrasive blade for rock cutting, or a diamond-tipped circular saw blade from your local hardware store.

Step 2

Push the blade lock button on the circular saw. This assists in changing the blade.

Step 3

Locate the blade changing tool (the "key") that came with your circular saw. It looks like a small wrench.

Step 4

Put the key on the bolt in the center of the blade. Twist to the left to unscrew the bolt completely.

Step 5

Pull up the blade guard on the saw to expose the blade.

Step 6

Lift the blade up off of the bolt and, and pull out. Do not lose the nut and washer that held the blade to the center bolt.

Step 7

Place the diamond or abrasive blade in the saw and on the center bolt.

Step 8

Put the nut and washer on over the new blade, turn right to twist tight.
