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.

The thread button bit, also known as a tap drill bit or a threading bit, is an essential component in the process of thread cutting. Its design incorporates a button-shaped projection at its end, which not only aids in the initial piercing of the material but also contributes to the accuracy and stability during the threading operation. The 'button' serves as a cutting edge, shearing off material as it rotates, gradually forming the required thread pattern.
