PURPOSE: A cutting saw for preventing noise is provided to reduce a noise by noise preventing member without melting the noise preventing member and to improve cutting work by selectively using cooling water. CONSTITUTION: A cutting saw for preventing noise comprises a cutting saw(10) having an iron plate(12); a through hole(18) formed on the iron plate; and a noise-preventing member(20) mounted in the through hole. The noise-preventing member is composed of lead, copper, zinc, silver, and aluminum. The cutting saw generates noise by cutting friction while cutting a material. Then, the noise-preventing member absorbs vibration of the cutting saw to prevent the noise of the cutting saw. The melting point of the noise-preventing member is higher than the melting point of the iron plate. Thereby, the noise-preventing member prevents the noise without melting the noise-preventing member. Moreover, the cutting saw for preventing noise improves cutting work by selectively using cooling water. The cutting saw for preventing noise performs the noise preventing function without using the cooling water in cutting the material.
