Patent ID: 7360975

Claim:
A milling head for a rotary tool, comprising: a substantially cylindrical body having a central axis and a bore extending into the body along the central axis for receiving an end portion of a tube, said body having a tool mounting connection located near a bottom axial end of the body and adapted to be connected to the rotary tool; at least one inner tube milling element for milling an inner diameter surface of the tube to a death below the end of the tube, said at least one inner tube milling element connected to the body and having a cutting surface located in the bore; and at least two outer tube milling elements for milling an outer diameter of the tube to a death below the end of the tube, the at least two outer tube milling elements connected to a milling element support of the body located at an upper axial end of the body opposite the bottom axial end by a securing element and each outer tube milling element having a cutting surface located a greater radial distance from the central axis than the cutting surface of the at least one inner tube milling element, wherein the cutting surface of each of the at least two outer tube milling elements is rounded or comprises at least ⅛ of a circumferential segment of a circle, wherein a portion of each of the cutting surfaces of at least two outer tube milling elements extends past the upper axial end of the body, and wherein a portion of each of the cutting surfaces of the at least two outer tube milling elements are located at a greater distance away from the bottom axial end of the milling head body when compared to the inner tube milling element cutting surface measured parallel to the central axis.
