Abstract: A bone graft harvester and method of use are described which produces bone grafts of superior quality to existing techniques. The bone graft harvester is driven in a reciprocating and impacting fashion when placed against bone to be fashioned at a rate of 500 to 20000 impacts per minute and with non-rotating longitudinal movements of 0.5 to 5 mm. Bone is collected in a hollow core of the hollow core coring tool of the bone graft harvester and can be retrieved therefrom for bone grafting procedures. Preferably the hollow core is tapered to allow expansion of the bone in the coring tool so as to better hold bone which is retrieved from the harvesting site.
