How to Use a Wet Saw to Cut Marble Tile


Cutting marble on a wet saw is a fairly easy and safe operation. The diamond blade, kept cool by running water, keeps the marble from becoming too hot and flaking apart. The blade is made to grind through hard materials and will not cut your hand without putting some effort into it. Marble is softer than most materials cut on a wet saw which makes it easier to cut, but also easier to break. Cut slowly to avoid breaking the tile.

Things You'll Need

  • Wet saw
  • Water bucket
  • Place the pan of the wet saw in an area where the sprayed water won’t make a mess. Fill up the bucket with water and place it by the pan. There is a pump attached to the back of the saw with a clear rubber hose. Attach the hose and put the pump in the water bucket. Keep an eye on the water level and don’t let it get too low.

  • Put the tray on the pan rails with the ruler markings toward you. Slide it forward and make sure it clears the blade. The bottom of the blade should stop just below the top of the tray in the center slot. There is an adjustment bolt on the back that allows you to raise and lower the blade.

  • Place the marble tile on the tray according to the ruled edge and the size cut you need. Check the marble against the edge of the blade to make sure the cut is correct. Slide the tray back toward you and turn the saw on. Push the tray holding the marble into the blade, holding the tile on both sides of the blade. Slowly apply a slight pressure and let the blade cut through the tile without binding or effort. As the blade approaches the back side of the marble, slow up even more to keep the blade from chipping off the back edge.

Tips & Warnings

  • Marble tiles are usually at least 12 inches. Depending on the size of the cut, you can sometimes get two cuts from each tile.
  • Always wear safety glasses when using this or any other power tool.
  • The wet saw will make a mess of water and marble dust. Set up in an area where this doesn’t matter or is easily cleaned.
