Expanders are used for enlarging the hole after the initial bore is made. The expander is designed for use with a pulling attachment and a steel cable. In addition, it must be assisted with a power winch or some other pulling equipment to assure continued tension on the cable. Front End Expanders are recommended for occasional use only.
