Abstract:
A saw blade comprising:a carrier blade having an outer edge; andat least one saw tooth mounted on the carrier blade at one end, said saw tooth having a straight cutting edge on an opposite end, said saw tooth also having convexly curved flanks positioned on both lateral sides of a plane of symmetry passing through the saw tooth and the carrier blade, said flanks extending more than halfway along both lateral sides from the one end of the saw tooth towards the cutting edge on the opposite end of the saw tooth, said cutting edge meeting with each of the flanks at a transition point;wherein a first spacing distance between a radial center of each of the flanks and the plane of symmetry is greater than a second spacing distance between the transition point and the plane of symmetry, said second spacing distance being greater than a third spacing distance between the outer edge of the carrier blade and the plane of symmetry; andwherein said straight cutting edge has a tetragonally trapezoidal cross section which is symmetrical with respect to the plane of symmetry.
