Abstract
A bone mill including a base and a mill head that is removably attached to the base. A cutting disc is moveably disposed in the mill head. A motor is disposed in the base. A spindle attached to the motor releasably engages the cutting disk. The spindle is also capable of movement towards and away from the motor. A spring holds the mill head away from the motor. In some versions of the invention, the spring urges the spindle towards the cutting disc. The biasing force exerted by the spring urges the spindle into engagement with the cutting disc. A locking assembly releasably holds the mill head to the base in opposition of the force exerted by the spring.
