Abstract
A glass cutting disc forms a scribed line on a surface of a glass product along which the glass product can be broken when an external force is applied thereto. The glass cutting disc includes an outer peripheral portion radially outwardly beveled to define a peripheral ridge. The peripheral ridge has surface features formed thereon so as to alternate in a direction circumferentially of the cutting disc. The surface features may be in the form of protrusions and grooves that alternate with each other over the peripheral ridge.
