A spinning insert for allowing the free rotation of a cutting tip (broadhead) relative to the rotation of an arrow is mounted to the tip end of the arrow and includes an insert having a flange that projects from the tip end of the arrow, a stepped and partially threaded cavity extending within the insert, a shaft axially projecting from the insert and concealed within the arrow, and a sleeve that is mounted to the shaft and abuts the interior annular surface of the arrow. The cutting tip is screwed into the cavity of the insert and the spinning insert is mounted to the tip end of the arrow so that the cutting tip can freely spin or rotate thereon and separate from the rotation of the arrow during the flight of the arrow and also when contact with a target (a game animal) is made thereby allowing the cutting tip to continue its rotation and rotate off matter, such as bone, providing for deeper penetration of the cutting tip within the body of the game animal from less draw weight resulting in a quicker and more humane kill.
