A digging tooth including a body portion and a plurality of hard water resistant conical inserts. The body portion includes a generally planar distal portion, a medial portion, and a bifurcated proximal portion having at least two prongs separated from each other to form a slot. The conical inserts are secured to and spaced along said distal portion and have a generally cylindrical body portion and a top portion which tapers to a point to form a tip, wherein the ratio of the diameter of the cylindrical body portion to the spacing distance between the tips of the conical inserts is between 0.50 and 0.80 and, preferably, 0.72.
