摘要： Disclosed is a diamond saw capable of reducing noise by installing a damper for absorbing vibration in a shank. The low noise diamond saw comprises: a shank formed of a circular metallic plate; and a diamond blade bonded to an outer circumferential surface of the shank, in which a damper is partially bonded to one or both of upper and lower surfaces of the shank by a spot welding. Said one or both of the upper and lower surfaces of the shank may be provided with recesses having a thickness enough for an uppermost portion of the damper not to be higher than an uppermost portion of the diamond blade According to another embodiment of the present invention, a low noise diamond saw comprises: a shank formed of a circular metallic plate; and a diamond blade bonded to an outer circumferential surface of the shank, in which a plurality of recesses having a predetermined depth are formed in upper an d lower surfaces of the shank in correspondence with each other in a circumferential direction, a hole having a diameter smaller than that of the recess is formed in the recess, and a damper is mounted in the hole so that a clearance may not be generated between a surface of the recess and a surface of the damper. In the diamond saw, noise is reduced as the number of the dampers is increased.
