摘要： Power tools with housings or hammer cases include a thin wall titanium shell tapering from a smaller forward section to a larger rearward section; with at least the rearward section having a wall with a substantially constant wall thickness and an interface flange that includes an outer perimeter profile that is curvilinear and defines a plurality of outwardly extending detents that provide an interference fit with the wall of the hammer case.
