An improved diamond tipped saw blade for cutting stone, concrete and similar materials having an innovative laminated core structure of metal and ceramic fiber material arranged to reduce operating noise, increase resistance to heat and significantly increase blade strength and wearability. Importantly, an innovative welding process is employed for attaching diamond cutting segments to the core thereby materially enhancing cutting performance of the blade and permitting replacement of worn cutting segments. Modifications of the aforedescribed blade structure are disclosed setting forth alternative structure of parts.
