ABSTRACT:
A bone mill including a base and a mill head that is removably attached to the base. A cutting disc is rotatably disposed in the mill head. When the mill head is attached to base, the cutting disc is rotated by a motor internal to the base. A plunger mounted to the mill head urges the bone against the cutting disc. The cutting disc and an impingement plate internal to the mill head shear the bone into chips. The chips are discharged from an opening in the mill head into a catch tray removably attached to the mill head.
