Old Dental Clinic Bits ( ex school ) check it out, all this came from a school dental clinic ( which closed some years ago , look at all the pics , will only sell as one lot at this stage , if it does not sell as one lot ? then may sell of as lots , I believe the drill and burr bits are used for bone carvers etc ? so if you collect old dental stuff ? then this is for you ? ot if you are into doing your own dental work then so be it ?
