ABSTRACT:
For extracting a test sample of fluid from a cable or the like, the present invention provides a combination drill and plug that has cutting means at one end thereof and tapered thread forming or cutting means proximate the other end thereof. When the combination drill and plug is driven forwardly by the apparatus and utilizing the method comprising the present invention, the cutting means thereof removes a mass of material in the form of chips and/or a disk and retains the mass of material so that it does not contaminate the fluid in the cable. After a suitable quantity of fluid is removed from the cable, the combination drill and plug is further advanced so that the thread forming or cutting portion thereof engages the hole formed by the drill portion and forms or cuts threads therein so as to seal the cable and permit its further usage without additional leakage of fluid.
