Abstract
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.
