Abstract: A vertically oriented particulate matter collector having a pan and a handle is disclosed. A lip abuts a flat vertical surface to be drilled, such as a wall. The lip when pressed against the wall prevents falling particulate matter from passing between the lip and the wall. A face, attached to the lip, follows the contour of the lip. A back, attached to the face, defines a cavity for collecting particulate matter. A mouth is defined by the opening of the cavity. A floor, opposite the mouth, attaches to the back and face. A collar at the seam joins the face to the floor. The collar projects a slope away from the back and the face. A toe provides support when the pan is set down. The handle, attaches to the mouth defining edge of the back.
