A total recovery drill assembly for providing a flowable cutting material discharging from a multiple orifice nozzle with the nozzle rotating around the longitudinal axis of the drill is provided herein. This assembly includes an outer tube that is connected to a vacuum source on a proximal end and terminates with grooves on the distal end. Within the outer tube is an inner tube that rotates within the outer tube. The proximal end of the inner tube is connected to a high pressure source for discharging a flowable material that is either a gas, a liquid or a particulate solid. The distal end of the inner tube is connected to a nozzle. The nozzle has a cutting orifice and an agitating orifice. The cutting orifice discharges the flowable material towards the grooves of the outer tube. Drilling is achieved by aiming the discharged flowable material as a laminar flow. Additionally, the nozzle has an agitating orifice designed to agitate the cut substance for removal by the vacuum. In an alternative embodiment, the drill has a second nozzle similarly designed and discharging either the same or different material.
