DonaldAttorney, Agent or FirmInternational ClassesB23D 057/00B23D 063/00 AbstractSolid carbide segments are brazed to the rim of a steel body and then teeth are ground into them. This allows more teeth/inch on the perimeter and larger diameter blades than on previous carbide-tipped blades. The segments, which typically form an arc of a circle, provide the improved performance of carbide blades without excessive expense of solid carbide blades. | |
