The anchor drill bit is typically made from high-quality materials such as tungsten carbide or cobalt, which offer durability and longevity. These materials are carefully selected for their ability to withstand the high pressures and temperatures generated during drilling. The bit's cutting edges are designed to be extremely sharp, allowing it to easily penetrate through hard surfaces without causing damage or deformation.

It was not until the development of the hydraulic drifter in the 1950s that rock drilling truly entered the modern eradrifter for rock drill. This innovative tool used high-pressure hydraulic fluid to power a piston that rotated the drill bit, allowing for much greater penetration rates and precision. The hydraulic drifter quickly became the go-to tool for drilling holes in hard rock, paving the way for many of the major engineering projects of the time.
