Abstract
A cutting segment for a cutting tool used for cutting or drilling a brittle workpiece, such as stone, brick, concrete and asphalt, a method of manufacturing the segment and a cutting tool provided with the segment are disclosed. The segment comprises a plurality of plate-shaped metal matrix layers laminated perpendicular to a cutting surface of the segment while being parallel to a cutting direction of the segment, the plate-shaped metal matrix layers being integrally combined with each other and made of a ferrous or non-ferrous material; and diamond particle layers arranged between the plate-shaped metal matrix layers such that diamond particles can be provided in an array on the cutting surface. The segment has an excellent cutting capability, and can be made by a simplified manufacturing process, thereby remarkably reducing manufacturing costs.
