- The 20th century saw further advancements in drill bit technology. The introduction of tungsten carbide and diamond-tipped drill bits revolutionized the industry by providing much longer wear life and allowing for drilling in harder materials such as steel and concrete. Additionally, the development of rotary drilling rigs and hydraulic hammers made it possible to drill deeper and more precise holes than ever before.
