Abstract
A tooth for a digging bucket of an excavator has a wedge-like profile formed by an end face (6) and two surfaces (4, 5) extending at an angle with respect to each other, one of which is undulated with at least two convex portions (8, 9) conjugated by a concave portion (11). The profile of the undulated surface (4) in the concave portion (11) is in the form of brachistochrone. A groove (7) is made in the end face (6) of the tooth to extend widthwise of the tooth.
