How to Cut Granite Slab


Granite is one of several different types of stone commonly used in home design, and can be seen in anything from bathroom tile to countertops. Granite is one of the hardest stones used in home projects, and that would seem to suggest granite would be extremely difficult to cut. Fortunately, this turns out to be untrue. In fact, granite can be cut with an ordinary wood-cutting saw -- provided it has the appropriate blade. This is not to say that cutting granite is a simple process, however.

Things You'll Need

  • Power saw or table saw, with continuous diamond-edge blade
  • Marker
  • Straightedge or tape measure
  • Sawhorses
  • Spray bottle of water
  • Safety goggles
  • Gloves
  • Don your safety apparel -- gloves and safety goggles are required. A thick jacket and a faceplate are also recommended to protect you from granite shards and splinters.

  • Place the granite slab on the saw horses or on the table saw so the polished side is facing up. You always want the polished side of granite facing up, as this will lessen the chance of a chip or crack in the polish while cutting.

  • Measure out your cut with a tape measure or straightedge. Draw a line along the tape measure or straightedge with your marker. You will follow this line with your power saw or table saw when you are cutting.

  • Position the blade of your saw so that it is almost touching the granite. Line up the blade with your marked line.

  • Turn on the saw and guide the blade slowly into the granite. Do not try to force the blade through the granite, as this could damage your saw.

  • Spray a light amount of water into the cutting area with your spray bottle every few seconds. This will help keep the saw blade from overheating.

  • Continue until you have finished your cut. Repeat Steps 2 to 6 as needed until you have successfully cut your granite slab into the desired shape.
