US12644683 - Archery arrow and related method of manufacture

An archery arrow is provided to include a shaft that is tubular and includes an exterior surface and an opposing interior surface, with an insert secured to the shaft. The insert can define a hole configured to join a component, for example, a broadhead with the arrow. The hole can be round and concentric with the exterior surface of the shaft, and in some cases non-concentric with the interior surface. The insert can be adhered to the shaft and later machined to define the hole to provide the concentricity of the hole and the shaft exterior or an associated outer diameter. When a component such as a broadhead is joined with the arrow via installation in the hole, the component can be centered relative to the shaft exterior. A related method of manufacturing an arrow is provided.
