ABSTRACT:
A combination digging tooth and holder therefor for use on excavating machines. Each holder has provisions by which it can be attached to an endless chain of a trencher or to a bucket lip. The forward part of the holder has an outwardly opening pocket formed therein of a particular configuration which receives part of the digging tooth in close tolerance relationship therewithin such that a forward marginal part of the tooth extends forwardly from the holder for engaging and digging in the earth. Each opposed marginal end of each of the teeth has identical cutting edges formed thereon so that a tooth can be reversed as well as being substituted one for the other. The teeth cooperate with the holder pocket in an unusual manner.
