A drive bar is a tool used to adjust the loft and lie of a golf club head. It is a metal bar with a series of holes that fit over the hosel of the club head. By turning the drive bar, the club head can be rotated to the desired loft and lie angle.
Using a drive bar is a relatively simple process. First, remove the club head from the shaft. Then, place the drive bar over the hosel of the club head and turn it until the club head is at the desired loft and lie angle. Finally, reattach the club head to the shaft.
