  • Patent number: 4688458
    Abstract: A bandsaw blade for use in milling timber having in-line swaged teeth, wherein the cutting tip of each tooth, in front profile, is triangular in shape with a central apical point (30) and two side points (32, 34). Preferably, the apical angle (.theta.) is from 60.degree. to 140.degree., with the base angles (.gamma.) of the tip being equal to one another and lying from 20.degree. to 60.degree., thus providing an elongate pentagon shape in front profile. Also, a dark blue temper band (50) may be curved so that its top is spaced below the apical point (30) by a distance of 0.5 to 1.3 times, preferably 0.6 to 1.2 times, the blade thickness.
