A water jet is an industrial tool capable of cutting a wide variety of materials using an extremely high-pressure jet of water. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods like plasma cutting, examples include plastic and aluminum. However, it can also cut steel, brass, and other plate metals
The water jet process is often used to achieve high tolerance, intricate cuts in very thick materials. Parts can be cut upwards to 6" thick.
