摘要： A remote cutter head (14) and a system (1) therefore which can operate in confined spaces are provided. The remote cutting system (1) including a cutter assembly (4) driven by a fluid source, a pushrod hose (10) coupling the cutter assembly (4) to the fluid source, a control assembly (8) detachably secured to the pushrod hose (10), and a monitor assembly (12) coupled to at least one camera (36). The monitor assembly (12) provides video images of the cutter assembly (4) and cutter assembly surroundings. The cutting head (14) including a fluid-driven gearmotor, the gearmotor including a two-piece housing (88,90), bearings (94), a pressure balanced gearmotor cavity (69), and two rotating members (70,72) provided in the pressure balanced gearmotor cavity (69), one of the rotating members protruding from the cutting head (14). High-pressure fluid provided to the cutting head (14) turns the two rotating members (70,72) to drive a cutting bit (74) attached to the rotating member (72) protruding from the cutting head (14). Also provided is a cutting bit (74).
