There are several types of rock drill button bits available, each designed for specific rock formations and drilling conditions. For example, dome-shaped buttons are ideal for hard and abrasive rock formations, while conical buttons are better suited for softer formations For example, dome-shaped buttons are ideal for hard and abrasive rock formations, while conical buttons are better suited for softer formations For example, dome-shaped buttons are ideal for hard and abrasive rock formations, while conical buttons are better suited for softer formations For example, dome-shaped buttons are ideal for hard and abrasive rock formations, while conical buttons are better suited for softer formationsrock drill button bit. By selecting the right type of button bit for the job, drillers can optimize their drilling efficiency and productivity.

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.
