Cutting tool for gang saw

A cutting tool for a gang saw, comprising:

• a blade configured to extend in a width direction or a length direction of a workpiece;
• at least one cutting tip protruding from a lower portion of the blade and configured to cut the workpiece while reciprocating in a swinging motion;
• and
• a joint portion disposed between the blade and the at least one cutting tip and configured to bond the blade and the at least one cutting tip by a brazing,
• wherein the joint portion includes a first brazing layer, a metal sheet layer disposed on the first brazing layer and having a melting point higher than a temperature of a brazing bonding process, and a second brazing layer disposed on the metal sheet layer,
• based on a direction in which the blade extends laterally, a length of the metal sheet layer constituting the joint portion is equal to, or greater in a lateral direction, than a length of the cutting tip bonded to the joint portion, and
• wherein in a blade region adjacent to the cutting tip, a heat-affected zone (HAZ) is disposed, and the joint portion is configured to have a size capable of covering at least a portion of a surface of the heat-affected zone.
