The science behind this tool's efficacy lies in its ability to maintain a consistent level of tension and compression throughout its length. As forces act upon the tapered drill string during operation, the variation in diameter ensures that stress is evenly distributed, reducing the risk of material fatigue and failure. This feature is paramount in deep wells or those that require extended reach, where the integrity of the drill string is constantly tested against the unforgiving subterranean environment.

One of the most well-known tunneling tools is OpenVPN, an open-source software application that implements virtual private network techniques to create secure point-to-point or site-to-site connections. It uses SSL/TLS encryption for security, making it capable of traversing firewalls that might block traditional VPN protocols. Another example is IPSec, which is built into many operating systems and provides secure tunneled communication over the Internet.
