A rotary cutter and end bit therefore is provided for cleaning and clearing debris and roots from a pipe. The cutter comprises a support housing having a plurality of radially extending skid fins, which help position the chain root cutter in the center of the pipe. The support housing carries a rotor and the rotor rotates relative thereto. A motor supported by the support housing is adapted to rotate the rotor. A plurality of linkages extends radially from the rotor and attaches at least one end bit to the rotor of the chain root cutter. The end bit comprises a hard wear resistant material, such as carbide, that faces radially outward and increases the wear life of the end bit. The wear resistant material may comprise carbide chips that continuously provide sharp edges over the life of the end bit.
