The Evolution of Drilling Over the History
From securing objects to underground exploration, humans have developed a range of sophisticated technologies to create holes of various shapes and sizes in all kinds of places.
But what was the evolution stage of all these technologies
As far back as the Stone Age, humans harnessed these forces by using bow drills to create fires as well as make holes. For fires, a blunt, smooth spindle was placed onto wood and rapidly rotated using a bow to set it spinning.
For large-scale earth-moving projects, such as the creation of cross-country rail links, Tunnel Boring Machines – or TBMs – are often the most effective solution. These giant machines feature huge drill-like rotating cutter heads, which make use of friction and pressure to chip away at earth and rock in order to burrow vast subterranean tunnels.
