Abstract

An abrasive pad for a manual grinding machine, in particular for an eccentric grinder, has a flat contact surface (13) on which an abrasive sheet is placed, and attachment means located on the contact surface (13) for creating an adhesive connection with the abrasive sheet. To reduce the production costs of the abrasive pad, it is made entirely—including the attachment means—of plastic using a single-component injection molding procedure, whereby the attachment means are designed preferably as hook-type fasteners (18) which extend out of the contact surface (13) (FIG. 1).
