![]() Most bits in use today can be broadly classified either as roller cone or fixed cutter bits. However, the development of synthetic diamonds in the early 1970s led to the creation of the fixed cutter, polycrystalline diamond compact bit-a significant departure from the three-cone bit that established a major branch off the bit's evolutionary tree. The two-cone rotary rock bit, patented by Howard Hughes in 1909, later evolved into a three-cone roller bit, which became the dominant bit design for much of the 20th century. The niche established by the fishtail bit was soon overtaken by the roller cone bit. In deep, hard formations, these bits tended to wear out quickly. The bit worked primarily by plowing or scraping away at the rock. This bit is shaped like a flat chisel whose blade is divided into two segments. At that time, rotary rigs relied on a fishtail, or drag, bit to drill the wellbore. Six years after this technique was introduced to the oil field, a steam-driven rotary rig was used to drill the Spindletop well in Texas, USA, further boosting the popularity of rotary drilling. The rotary drilling rig uses a spinning rotary table to transmit torque to the drillstring and the bit. Instead of using the chisel as a percussion tool, the rotary drilling technique bored a hole by rotating the chisel. However, cable tool drilling was slow and was eventually eclipsed by a new approach developed in the early 1880s for drilling waterwells. In 1859, cable tools helped launch the modern oil business when they were used to drill the first commercial US well in Titusville, Pennsylvania. Before the drill bit's development, many wells were drilled using cable tool technology, in which a steel cable repeatedly lifted and dropped a heavy spike or chisel into a borehole to break and crush the rock. The drill bit has evolved throughout the relatively brief history of the modern petroleum industry. Translating surface horsepower into brute force downhole, the bit gouges, shears or crushes rock as it drills. Of all the equipment found on today's drilling rigs, perhaps none has undergone more change than the drill bit. Ideal for jewelers, mold makers, embossing, die makers. It is well known that the smaller the tip size the weaker the tool, but because these end mills ‘taper out’ they will have much more strength.
