摘要： The invention provides a cutting segment for a cutting tool for cutting or drilling a brittle work piece such as stone, bricks, concrete and asphalt, and a cutting tool having the cutting segment. The cutting segment includes a cutting surface for cutting a work piece and a plurality of abrasive particle layers. The abrasive particle layers are disposed perpendicular to a cutting direction. Each of the abrasive layers has a plurality of abrasive particle rows in a width direction of the cutting segment. Each of the abrasive rows has a plurality of abrasive particles arranged in a line. Further, the abrasive layers have a plurality of blank sections therebetween. In the blanks sections, abrasive particles are absent or have a concentration of 70% or less with respect to those in the abrasive rows. In addition, the blank sections include relatively thick blank sections and relatively thin blank sections.

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 R 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.
