By pressurizing water into thousands of pounds per square inch and emitting it at high velocities through a tiny orifice, water jet cutters are able to cut through a diverse range of mat erials. Pure water jets are used in softer, lighter applications such as food, foam, and paper cutting. The addition of garnet sand works as a tool in water jet stream and enables the unit to be used for cutting large thickness granite, metals, tile, and other hard materials with precision .
