Abstract
An abrasive tool includes a first perforated sheet having a front surface and a back surface, and a second perforated sheet having a front surface and a back surface. A first layer of abrasive grains is bonded to the front surface of the first perforated sheet and a second layer of abrasive grains is bonded to the front surface of the second perforated sheet. A core is made of a first material, the core having a first surface and a second surface, the back surface of the first perforated sheet disposed adjacent to the first surface of the core and the back surface of the second perforated sheet disposed adjacent to the second surface of the core, the core being bonded to the first perforated sheet and the second perforated sheet by forming the core between the first perforated sheet and the second perforated sheet.
