screw extraction trephine
Once the head of a screw has become detached the shaft can be very difficult to extract, particularly when the screw has been in situ for some time. The Screw Extraction Trephine is designed to ‘core out’ the screw shaft either in its entirety or partially to allow the screw to be grasped by extraction forceps. The internal diameter is a little larger than the screw to be extracted. The external diameter is small enough in most cases to allow the replacement of the screw by a larger one.The Trephine fits directly into a Jacobs Chuck.
