yt29a air leg rock drill of the rock drill bit came about as a one-piece tool, featuring a single cutting edge that could be linked up to the drill string. As the bit spun upon application of the drill string's torque, the immense weight of the string pressed down to give the cutting edge its force to break through and grind away at the rock.
Thousands of years ago, man-powered rock drills were used to create openings in rock faces, primarily for mining activities. These drilling tools additionally served as the preferred drill bits for water and oil wells of the period. Without them, excavating operations would have been impossible.
As technology has evolved, so too has the rock drill bit. Originally fashioned from materials that just barely surpassed the hardship of the rocks they were intended to bore through, current offerings are crafted of tungsten carbide - a substance incomparably tougher than its task. And with variances in size and shape, these indispensable tools come in all possible iterations.
A threaded connection binds the bits to the drill string, which is then spun by a drilling machine. The weight of this length of pipe pushes the bit down as its cutting surface slices through the rock.
Constructed from tungsten carbide, an extremely tough material harder than the rocks to be drilled, rock drill bits come in an array of sizes and shapes to accommodate numerous deep-burrowing tasks. Whether the job requires fine detailing or heavy-duty penetration, the right bit for the operation is easily obtainable.
