A fluid jet assembly includes a non-pressurized lance barrel through which a high pressure hose (“a lance hose”) is threaded and anchored at the distal end of the lance barrel relative to an operator's position. The other end of the lance hose is coupled to a high pressure fluid source. The fluid is fed into the lance hose and transported to the output of the lance barrel, where it is discharged as a fluid jet stream. A nozzle is mounted at the output of the lance barrel to control the characteristics of the fluid jet flowing out of the lance hose. When infused with an abrasive material, the fluid jet stream exits the nozzle in a focused jet capable of cutting through most structural surfaces.
