摘要： The present invention relates to a diamond tool for cutting a workpiece. An object of the present invention is to provide a diamond tool, wherein a wear-resistant region is formed in a connection portion between a segment and a shank of the diamond tool to prevent an under-cut phenomenon, to extend the service life of the diamond tool and to improve cutting quality due to easy discharge of cut chips. A diamond tool of the present invention for achieving the object has a cutting segment that contains a plurality of diamond granules and is attached to an outer peripheral surface of a shank, wherein the segment comprises an auxiliary cutting portion that has a thickness identical with that of the shank and a height and is attached to the shank; and a primary cutting portion that is integrally formed on the top of the auxiliary cutting portion and has a thickness larger than that of the auxiliary cutting portion.
