摘要:
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.
