A diamond abrading disc having a discontinuous pattern, and a method for making such a disc, distributing a layer of diamond particles over an abrading surface in a disc body having interspersed conductive metal zones and resist zones, and initially bonding the diamond particles to the metal zone by electrodeposition of nickel while the disc body is in horizontal position in an electrochemical bath. The diamond particles at the resist zones are then dislodged by tilting and shaking the disc body, and then repositioning the body vertically in the bath so that the initially bonded diamond particles at the metal zones may be finally bonded with further electrodeposition of nickel. The resist zones may be provided by applying resist material on a metal surface of a disc through a pattern of openings in a screen. Alternatively, conductive metal zones may be formed on a body of non-conductive material, which otherwise are resist zones.
