Abstract

This product is a diamond grinding wheel in which an annular raised section is provided on the circumference of a disc-shaped metal plate, and a diamond abrasive layer is formed on both sides of the disc from a position where the raised section is shortened to the outer edge of the disc, as well as on the outer surface of the raised section. This product is used to simultaneously grind the tip relief surface and the rake surface of the cutting edge of a brush cutter's saw blade by facing the peripheral edge of the disc and the diamond abrasive surface of the raised section toward each other.
