摘要

A device for boring a well. The device is attached to a motor that has a power shaft for imparting rotational movement. The device comprises a driver operatively connected to the power shaft, with the driver containing a tubular body, a first bit having a first end connected to the driver so that rotational movement of the driver is imparted to the first bit, and a sleeve disposed about the power shaft, and wherein the sleeve has a radial shoulder. The device further comprises a housing disposed about the driver and a second bit attached to the housing. A plurality of nozzles is operatively placed within the driver, and the nozzles deliver fluid flow to the second bit. The device may further include a planetary gear anchored to the radial shoulder, and wherein the planetary gear is adapted for imparting rotation from the driver to the housing in a counter radial direction.
