Abstract
A wall anchor for use in a friable material, composed of a generally cylindrical body having a flanged end, a central portion, and a drill end. The drill end has a generally flat blade which includes a first portion and a second portion. The first portion has a first angled cutting edge and a first side cutting edge, and the second portion has a second angled cutting edge and a second side cutting edge. These portions are formed on a common line and are offset relative to each other along a plane passing through a diameter of the cylindrical body, and these portions together form a point. The central portion and the flange end have a combined axial length, and the drill end has an axial length which is shorter than that of the central portion and the flange end.
