Abstract: Digging edge structures for buckets of earthmoving machines, excavators, loaders, and the like. A bucket wall which has a front cutting edge region is formed with a notch which receives a receptacle of a hard, wear-resistant material. This receptacle is made up in its entirety of only a single pair of shells which are welded to each other and define the hollow interior of the receptacle, this hollow interior having a front open end through which a tang of a bucket tooth is adapted to be inserted into the hollow interior of the receptacle to be removably fastened therein in any suitable way. These shells which form the receptacle are welded to the bucket wall and at least one of the shells has a pair of laterally extending front lips which extend along the cutting edge region of the bucket wall while being welded thereto.
