Multiple abrasive grinder consisting essentially of a series of discs of an abrasive material, between which is disposed, in its center or core, disks or rigid separating washers that cover a reduced area from the central hole, being occupied the remaining area of the gap between two abrasive discs, by a complementary crown of elastic and debris-resistant material. Which, due to its constitution, allows its peripheral edge to be torn or broken up into small particles during the work of the wheel and due to rubbing or friction on the surface of the material being worked, producing a peripheral recess in the form of a channel, in the edge of the filling material, with which an effective cooling of the wheel is obtained and less heating of the material on which it acts.
