Diamond drill bits for making or coring holes into marble surfaces

Marble core bits are a hollow cylindrical bit that is the cutting part of a core drill. It leaves a cylinder shape which often is used as sink holes or to feed lines and pipes. These marble hole saws and cutters are made up of a concentration of diamonds and metal bonds in order to cut the hard surface of the granite. Marble core bits are occasionally Vacuum Brazed or Electroplated. The zsstore.shop offers two options, dry and wet diamond drill bits.
