Coax Tools Coaxial Cable Tools As far as standard cable goes, coax is usually what we think of. Even though it is still used regularly around the home and business, the cable will still need some maintenance over time. When you need to troubleshoot, you should make sure you have the proper tools. At HNSTools, we have the right coaxial cable tools to help you get the job done. Coax cable features an inner conductor, typically copper, that is surrounded by an insulating layer that is then inundated with a tubular conduction shield, typically an outer plastic with an inner woven copper. This design helps to produce a meticulous, consistent conductor spacing to provide more efficient results. In fact, the term coaxial actually stems from the fact that the conductor inside shares a geometric axis with the outer shield that surrounds it.
