ABSTRACT:
This invention provides an improved backup pad for an abrasive disk adapted to permit a view of surface as it is being ground which comprises a compressible pad and a relatively rigid support member laminated to the pad that has shorter radial dimensions than the pad in those portions of the circumference of the pad that are likely to snag an angled surface during grinding. The result is that abrasive disks borne on the pad are less likely to tear from such contact.
