A drilling assembly includes a hydraulic amplifier assembly, a driver, a bearing housing, and a shaft. The hydraulic amplifier assembly is configured to increase a pressure of a drilling fluid so as to produce a pressurized drilling fluid. The driver is driven by the pressure of the drilling fluid and is configured to rotate a drill bit. The bearing housing is coupled to the driver. The shaft extends through the bearing housing and is configured to be coupled to the drill bit. The shaft is driven to rotate by the driver. The hydraulic amplifier is configured to deliver the pressurized drilling fluid to the drill bit.
