How to cut marble with a grinder

Updated February 21, 2017

Marble is a natural material used in the construction industry for flooring and countertop fabrication. This porous stone is considered a soft material when compared to stones such as granite. Cutting marble is a delicate process that requires precision cuts to achieve a professional result. Patience and the proper blade are crucial to avoid damaging the marble, which could be expensive to replace. A grinder is an ideal power tool to cut marble when outfitted with a diamond-cutting blade.

  1. Place the marble on a sturdy workbench or table with an area large enough to hold the marble so that it does not overhang. Marble has many veins that are its weakest points. Allowing the marble to hang over the edge of the workbench while cutting may cause it to break.

  2. Attach a diamond-cutting blade to an angle grinder. Most home improvement centres sell a wide variety of diamond-cutting blades.

  3. Make accurate marks on the surface of the marble in the location of the cut using a pencil or white correction pen.

  4. Apply light pressure when cutting the marble with the angle grinder. Work the grinder so that it slightly penetrates the surface of the marble along the cut line.

  5. Cut all the way through the marble on both ends of the cut line. This helps to prevent the marble from breaking during the cutting process. Finish cutting the middle of the cut line until the cut is complete.

  6. Tip

    Be patient and do not rush the cut -- marble is a very delicate stone.


    Wear safety glasses when cutting stone or using power tools.
