ABSTRACT:
A scarfing tool for scarfing the inside of a tube-like member in which an elongated body is adapted for attachment to the end of an impeder rod. The body includes a cutting tool and a pair of spaced apart rollers aligned with the cutting tool. A thrust roller is pivotably mounted to the side of the body opposite from the cutting tool and rollers to force the cutting tool against the inner area of the tube member to be scarfed. A pair of first and second hydraulic means having associated pistons which are connected to a common source of hydraulic fluid. The first hydraulic piston is operably connected to said thrust roller for actuating said roller into extended contact with the inner tube member and the second piston is operably connected to a bias means to work against said means as the thrust roller is extended by the first hydraulic piston.
