<p>A universal abrasive article (100) adapted to mount on a mounting surface of a sanding machine having a plurality of dust extraction holes that define an open area. The abrasive article includes a plurality of discrete apertures (110) that are sized and positioned so as to expose a majority of the open area of the dust extraction holes (130, 135) independent of the angular orientation of the abrasive article when the abrasive article is in registration with the mounting surface. The discrete apertures may include elongated, arcuate slots that may be symmetrically positioned about a center point of the abrasive article. In one embodiment, the discrete apertures may include seven arcuate slots (210). These embodiments also include sufficient abrasive material to provide adequate sanding cut rate and structural integrity during use and removal.</p> |
