A rotary saw blade, comprising a series of outward tapering toothlike radial projections on and around a circular core of a base plate of metal, each of said projections comprising a leading surface which is inclined at an angle not greater than 60.degree. to the periphery of the core and deposited with abrasive particles held in an electro-deposited layer of metal.
A rotary saw blade comprising a series of outward tapering toothlike radial projections, each of which comprises a leading surface inclined at an angle not greater than 60.degree., along which a powder metallurgically formed tip comprising particles of abrasive is secured, said abrasive consisting of at least one selected from diamond and cubic- and wurtzite-type boron nitrides.
