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. | InventorsApplicationNo. 370066 filed on 08/06/1999US Classes:83/838, Plural separable sections76/27, Roller76/112, Saws83/835Toothed blade or tooth thereforField of Search76/25.1, SAW-MAKING OR FURBISHING DEVICE OR MACHINE76/24.1, Process76/101.1, BLANK OR PROCESS76/112, Saws76/27, Roller125/15, Saw blades83/835, Toothed blade or tooth therefor83/838, Plural separable sections83/840, By independent connecting element83/845, By deformation83/854Teeth having cutting edge parallel to blade surfaceExaminersPrimary: Bray, W.
