    Yorvik Minerals | Your industrial garnet supplier

    The largest industrial use of Garnet in North America is in Waterjet cutting. A machine known as a waterjet cutter produces a high-pressure jet of water with entrained abrasive granules. When these are directed at a piece of metal, ceramic, or stone, a cutting action can occur that produces very little dust and cuts at a low temperature.
