Abstract

A milling tool for forming recesses, such as an undercut in a borehole, in masonry, concrete and similar material structures includes a tool shaft with a bearing pin extending outwardly from one end of the shaft and with the axis of the pin offset eccentrically to the axis of the tool shaft. A freely rotatable annular milling head is positioned on and encircles the bearing pin. The outside surface of the milling head has cutting edge members.
