  • Patent number: 10710181
    Abstract: A saw blade (10) comprises a generally circular blade base body (100), and a plurality of teeth (101a, 101b), extending radially from the base body (100). The teeth (101a, 101b) are alternatingly set towards opposing axial (A) directions of the saw blade, such that each tooth presents a respective tooth plane, which is angled relative to a base body plane. The teeth (101a, 101b) present a respective first cutting edge (102a, 102b), extending along a radially distal edge portion (103) of the respective tooth, along a length of the tooth, as seen in a direction of rotation of the saw blade. The radially distal edge portion (103) presents a first bevel (104), providing a first bevel surface (105) which is non-perpendicular relative to the tooth plane. The radially distal edge portion (103) presents, at a radially outermost portion thereof, a hard portion (106) having greater hardness than the base body (100). The saw blade can be used in a brush cutter.

  • Publication number: 20190160566
    Abstract: The present disclosure provides a method of producing a saw blade (10), comprising providing a saw blade blank, comprising a circular blade base body (100) with radially extending teeth (101), said teeth being in an initial position, in a first bending step, bending at least some of the teeth (101), such that the teeth are plastically deformed, towards an axial direction (A) of the saw blade blank, to an intermediate axial position (N?), and in a second, subsequent, bending step, bending said at least some of the teeth (101), such that the teeth are plastically deformed, towards an opposite axial direction (?A) of the saw blade blank, such that the teeth arrive at a final axial setting position (N?). In the method, the intermediate axial position (N?) is axially beyond the final axial setting position (N?).
