Solid 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

Solid 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.

[ What is claimed is:] [1.]1. A circular saw blade, comprising:a plate, made of a metal; andone or more multi-tooth segments which are affixed to the perimeter of said plate;wherein each said segment includes multiple teeth, integrally formed with said segment, which protrude outwardly from said perimeter of said plate;and wherein each said segment is made of a super-hard material, which is harder than said metal, and which has a hardness greater than 90 on the Rockwell A scale.
