Abstract
An abrasive tool comprises a base and an abrasive powder bonded to the base in the form of a single-layer structure in which the particles do not substantially overlap or rest one upon another. For the bonding purpose the abrasive powder is either dispersed in a dilute solution of a binder resin and a solvent for subsequent application of the solution to the base or is spread over and fixed to a binder resin coat formed beforehand on the base.
