Abstract
A circular saw blade includes a substantially planar main body having an essentially circular periphery in which are formed a plurality of annularly spaced tip support portions, and a plurality of cutting tips affixed by brazing to the tip support portions of the main body. Each cutting tip has a mounting base formed with at least two locking surfaces along which the brazing affixes the mounting base to a respective tip support portion. The locking surfaces are configured and located in relation to one another and to the main body for counteracting forces which act against the cutting tip in differing directions in the plane of the main body during rotational cutting operation of the blade.
