Abstract
A flexible sanding/deburring head adapted for driven rotation by a power tool is formed from a plurality of juxtaposed thin sheets of flexible abrasive material individually die cut to define a connecting portion having a mounting opening disposed centrally thereof and at least three projections connected to the connecting portion to extend generally radially of the mounting opening, wherein the projections are uniformly spaced annularly of the mounting opening and bound uniformly sized cut-out areas opening radially of the mounting opening and each projection is divided into parallel fingers having relatively inner ends connected to the connecting portion and relatively outer ends arranged to lie generally along arcs of a circle whose center is coincident with the center of the mounting opening. The projections are skip-cut to define the fingers.
