Abstract: A wear member includes a forward working portion that is disposed along its longitudinal axis including a closed end, and a rear attachment portion that is disposed along the longitudinal axis including an open end with an exterior surface, and an interior surface. The interior surface defines an interior counterbore with a major diameter, and a minor diameter. A ratio of the major diameter to the minor diameter ranges from 1.8 to 2.2.

Abstract: A spring loaded retainer includes a lug receiving portion defining a first maximum outside dimension, the lug receiving portion also defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. A drive portion defines a second maximum outside dimension, and a first flat is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall.

Abstract: A decision model is applied to a set of current data from a mortgage portfolio to generate a first portfolio metric. The decision model is formed from a network of a plurality of predictive models that are trained on historical data derived from a plurality of mortgage account profiles for a plurality of mortgages within the mortgage portfolio. One or more of the predictive models is an action-based predictive model allowing modification of at least one attribute affecting performance of the mortgage portfolio. One or more of the attributes can be modified and a second portfolio metric can then be optimized, using the decision model, in light of at least one constraint (which can be user-defined). Related techniques, apparatus, systems, and articles are described.
