Abstract
A wear member may include a front end and a rear end and a longitudinal axis extending therethrough. The rear end may have a cavity formed therein with a rear portion and a forward portion. The cavity may have two horizontal surfaces in cross-section and converging toward the longitudinal axis. The cavity may have four substantially planar surfaces that are oblique in cross-section. A first two of the four substantially planar surfaces may be disposed on a first lateral side of the two horizontal surfaces, and a second two of the four substantially planar surfaces may disposed on a second lateral side of the two horizontal surfaces. An intermediate portion may be disposed between the rear portion and the forward portion, with the intermediate portion comprising a different number of surfaces in cross-section than a number of surfaces of the rear portion and the forward portion in cross-section.
