摘要： The present invention relates to a cutting tip for a cutting tool, which is used in cutting or drilling a brittle workpiece such as stone, bricks, concrete, and asphalt and has an excellent cutting speed and a long lifetime, a method of manufacturing the cutting tip, and a cutting tool including the cutting tip. The cutting tip includes an abrasive material and a sintered bonding material, wherein the bonding material is formed of a metal matrix; the metal matrix includes a phase II and/or pore having a certain size at a certain volume fraction; and the phase II is one of a non-metallic inclusion and ceramic. According to an aspect of the present invention, there is provided a cutting tip having excellent cutting speed and a long lifetime at a much lower price.
