Claims

[Scope of Claim for Utility Model Registration] In a grinding tool such as a blade or saw chain in which a grinding wheel segment containing abrasive grains such as diamond is fixed to a tool base as a blade portion, the grinding wheel segment is composed of two or more types of grinding wheel segments. A grinding tool characterized in that the contact width of each grindstone segment with respect to the workpiece is smaller than the grinding width, and the cutting positions are appropriately arranged so as to be shifted one after another.
