PURPOSE: A cutting edge coupling structure of a cutting tool for machining a piston ball seat of a vehicle compressor is provided to carry out the cutting and abrasion of a synthetic diamond by desired dimensions and chamfering the upper part of the cut surface of the diamond before inserting the diamond to an abrasion rod, thereby preventing the motion of the diamond in advance and improving the workability. CONSTITUTION: In a cutting edge coupling structure of a cutting tool for machining a piston ball seat of a vehicle compressor, semicircular synthetic diamond(10) has the length from the center, is coupled with a solid carbide edge(12) on a rear surface, and formed with a chamfer at the upper part of a cut surface, the diamond is inserted into a groove(15) formed to a cutting rod(14) of a cutting tool(13) with a predetermined depth and a predetermined width, many copper plates are inserted into a space between the inner wall of the groove and the solid carbide edge with a predetermined interval to fix the diamond, and a silver solder is inserted in a space between the inner wall of the groove and the copper plates to be melted by a welding element to couple and fix the diamond to the cutting rod.
