ABSTRACT An abrasive member for surfacing a workpiece by rotary abrasion under a flow of liquid, comprises a base and a plurality of abrasive segments protruding from the base. The abrasive segments are shaped and arranged in spaced relation to one another so as to form a network of intersecting primary and secondary channels, the secondary channels cooperating with the primary channels to effect substantially complete scavenging of detritus by centrifugal drainage of waste liquid carrying the detritus through both the primary and secondary channels to the outer periphery of the abrasive segments. Each abrasive segment has a planar working surface for abrading contact engagement with the workpiece and a bevelled leading edge which defines a sloping abrasive surface permitting the abrasive segments to ride up over surface irregularities protruding from the workpiece during rotation of the abrasive member, whereby the sloping abrasive surface cooperates with the working surface to grind the surface irregularities without causing chipping of the workpiece.
