The invention refers to a backing pad (100) for use with a hand-held or hand-guided orbital sander (10) or polisher. The backing pad (100) has a planar extension and an essentially triangular form comprising a triangular region (102), with a top surface for releasable attachment of the backing pad (100) to the sander (10) or polisher and with a bottom surface for releasable attachment of a sheet-like sanding or polishing member (132) to the backing pad (100). In order to provide for a possibility to sand or polish surfaces within narrow, cramped, tight, twisty and crooked spaces with a sander (10) or polisher having an essentially triangular backing pad (100), it is suggested that the backing pad (100) comprises at least at one of the three corners (104) of the triangular region (102) a protrusion (108) extending in the plane of the planar extension of the backing pad (100) and projecting laterally beyond the triangular region (102).
