A portable flange facer may be used to machine flange faces without removing the pipe from its installation thereby avoiding extensive disassembly and downtime. A stationary spindle, mounted centrally within the pipe bore, provides a structure about which a main body rotates. A motor, mounted upon the main body, and a gear means, coupling the motor to the stationary spindle, are used to rotate the main body about the spindle. A cutting element, mounted upon a turning bar slidable within the main body, may be moved radially inwardly and outwardly by manual or automatic means. The flange facer may be used to resurface a flange face or to form circular grooves therein.
