33196 CAN 3A Abstract of the Disclosure A flexible, low mass coated abrasive sheet material magnetically held on a support surface of a magnetized pad providing more than 6 magnetic poles per inch in one direction along the support surface. The coated abrasive sheet material incorporates sufficient ferromagnetic material that only the force of magnetic attraction between the magnetized pad and the ferromagnetic material and any force applied to the sheet material through the magnetized pad normal to the support surface will produce sufficient static friction between the support surface and the coated abrasive sheet material to retain the abrasive coated sheet material on the support surface while it is driven by the magnetized pad to abrade a workpiece.
