<p>A milling head particularly useful for cutting sharp interior corners in a workpiece, includes a rotary shaft coupleable to the rotary drive of a milling machine so as to be rotatable about the shaft longitudinal axis; and a conical cutter member coupled to the rotary shaft so as to be rotated thereby about a rotary axis at an angle with respect to the shaft longitudinal axis. Preferably, the conical cutter member defines a cone angle of 70 degrees, and its rotary axis is 55 degrees with respect to the longitudinal axis of the shaft. The conical cutter member is disposed within a case and is aligned with an opening in the case, such that the external surface of the case, engageable with the workpiece, is effective to align the conical cutter member with respect to the surface of the workpiece to be milled, and to enable the conical cutter member to cut sharp internal corners in all three dimensions.</p> |
