ABSTRACT:
A milling head for a rotary tool, which is preferably utilized to process, prepare, or otherwise impart a desired finish to a workpiece, preferably an end portion of a tube. In a preferred embodiment, the milling head includes at least three different cutting or milling surfaces each capable of performing a distinct operation on a workpiece. In one embodiment, the milling head includes a) a membrane milling and/or outer diameter tube film removal element; b) a beveling element capable of imparting a bevel to the tube end; and c) an inner diameter tube film removal element. In yet a further embodiment, outer diameter tube film removal elements or blades are provided having a curved or rounded cutting or milling edge which can be utilized especially in milling operations having close quarters. In a preferred embodiment, the milling head outer diameter cutting blades are provided with elongated, slotted bores.
