摘要： The invention relates to a cutting segment of a diamond tool for cutting or drilling a brittle workpiece such as stone, bricks, concrete and asphalt, and a diamond tool having the same. The invention allows superior cutting rate and lengthy useful life without suffering from wear during cutting. In the cutting segment, a number of diamond particles are arranged in a plurality of plate-shaped layers stacked perpendicular to a cutting direction. Each of the diamond particle layers has a plurality of particle rows on a cutting surface. Further, at least two of the diamond particle layers are superimposed on at least one side of the cutting segment seen from the front of the cutting segment in cutting direction. The invention ensures uniform cutting by significantly reducing R wear that arises during cutting and thus enables superior cutting rate and longer useful life.

摘要： The present invention relates to a cutting tip for a diamond tool and a diamond tool having the same which serve to cut or perforate various brittle materials such as stone, brick, concrete and asphalt. In particular, the cutting tip for a diamond tool and the diamond tool have diamond particles which are suitably arrayed to improve the cutting rate. The present invention provides a cutting tip for a diamond tool having diamond particles which are distributed in the cutting tip, wherein the diamond particles are inclined in respect to a cutting direction in a plane parallel to a cutting surface, and arrayed whereby grooved channels are formed successively overlapped on a brittle substance in cutting operation.
