ABSTRACT:
A drilling machine especially adapted for reaming tubes includes an elongated hollow drive shaft having a cutterhead attached to its forward end and a drive piston attached to its rearward end. Fluid pressure is applied to the rear end face of the drive piston in order to propel the drive shaft forward, while concurrently supplying fluid which flows out through openings in the cutterhead so as to flush the materials being reamed from a tube that is being cleaned. The machine includes a reversible drive flow for the fluid pressure system. It also includes a separate rotating drive for imparting rotation to the drive shaft.
