A rasp for use in spine surgery comprising:

• a circular head portion for fitting within an intervertebral space between two adjacent vertebral bone plates and having an upper face and a lower face and an outwardly disposed surface extending between said upper and said lower face, and wherein at least a portion of one of said upper face, said lower face and said outwardly disposed surface includes a rasp surface;
• and
• a shaft extending from said outwardly disposed surface to permit said head portion to be angularly displaced at least slightly within said intervertebral space, and
• wherein said rasp is a roughing combination rasp having a rasp surface on at least a portion of said outwardly disposed surface and upon on at least a portion of at least one of said upper and said lower faces, so that said circular head portion may be rotated about a center to remove intervertebral material.
