A dead blow hammer head with end caps coupled to a central body through an interference fit. The ends of the body can be flared axially and radially outward and interference fit with the recesses to maximize the surface area overlap between the ends of the body and the recesses. By maximizing the surface area overlap, stress concentrations and failure are reduced. The hammer head can also include a shot or other mass that is unobstructed by screws or pins due to the interference fit of the hammer head components. The interference fit can become stronger during use with each impact further solidifying the surface area overlap between the ends and central portion of the hammer head.
