A diamond tool having segment type cutting tip for use in apparatus such as cutting saw machine, grinding wheel machine, and core drill machine, having a structure which cutting tip is able to produce cutting chips with relative large size during cutting operation so that produced chips are easily discharged outside to reduce the friction with cutting tip of tool, thereby to increase cutting ability and to prevent cutting chips dispersing in the air and giving rise to the bad effects to user's health and the contamination of environment. The diamond tool according to the present invention comprises a wheel body connected with a shaft of electric motor, and cutting tip for cutting, grinding or drilling crushable materials comprising a plurality of diamond layer segments disposed at predetermined intervals on the circumference of wheel body, each of diamond layer segments having at least two diamond layers longitudinally disposed parallel with the rotation direction of the tool in which diamond particles are included, and non-diamond portion disposed between the diamond layers in which diamond particles are not included.
