Abstract
The present invention relates to an improvement of the conventional sandwiched type saw blade shank by providing, as the intermediate layer, a coated thin sheet with tens of electro-conductive points or a thin sheet with multiple contacts to enhance weldability and to minimize the thermal deform or pressed marks, so that sound absorption, noise reduction and also heat dissipation may be maximized during a high speed cutting operation. The invention provides a saw blade shank with cutting tips on the circumference of the shank, comprising two or more conductive steel plates (22,24) and coated thin sheet (30) as an intermediate layer inserted between the neighboring conductive steel plates, the coated thin sheet being coated so as to leave a plurality of uncoated areas (32a) on at least one of its surfaces, whereby the coated thin sheets (30) and the steel plates (22,24) are integrally combined by multi-contact thermal fusion through a predetermined high pressure and electric current concentrated on the uncoated areas (32a).
