Abstract
A milled tooth (22) is provided having a back face (38), including an upper back face surface (58) and a lower back face surface (60). A tip or top surface (36) is provided below the upper back face surface (58). The upper back face surface (58) is in a recessed position relative to the lower back face surface (60). A gage rib guide (64) runs along one side of the lower back face surface (60). A layer of hardfacing material (33) is applied to the milled tooth (22) so that the layer (72) applied to the lower back face (60) surface is flush with the gage rib guide (64) and the layer (74) of hardfacing material (33) is thickest in the region of the upper back face surface (58).
