Power Tools with Titanium Hammer Cases and Associated Flange Interfaces

1. A power tool, comprising:

an external titanium housing having a forward portion and an opposing rearward portion and a cavity extending therebetween, wherein the titanium housing has a body of titanium with at least a major portion thereof, including a rear section thereof, having a thin wall with a substantially constant thickness;

an interface flange residing in the titanium housing cavity; and an external motor housing extending rearward of the external titanium housing and attached to the interface flange, wherein the interface flange is internal with respect to the external titanium housing and external motor housing,

wherein the interface flange has a plurality of corner detents extending outwardly thereby defining at least a portion of an outermost curvilinear perimeter thereof, the corner detents provide an interference fit with corners of an inner surface of the titanium housing; and

wherein the interface flange comprises at least one transversely extending recess, and wherein the titanium housing comprises at least one inwardly extending projection that cooperates with the at least one transversely extending recess.
