Abstract (en)
[origin: WO9303887A1] A flexible sanding/deburring head (10) adapted for driven rotation by a power tool is formed from a plurality of juxtaposed thin sheets (38a-38d) of flexible abrasive material individually die cut to define a connecting portion having a mounting opening (42a-42b) disposed centrally thereof and at least three projections (44a-44d) 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 (48a-48d) 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.
