A method for improved penetration of a work material using a high velocity fluid jet from a nozzle element by providing a sealed chamber between a surface of the work material and the nozzle element is described. With hard and/or irregular materials, a deformable element is provided between the nozzle element and the work surface so that the deformable element conforms to the surface to effect the seal.
