The 7 degree refers to the angle at which the cutting edge of the button bit is set. This particular angle is not arbitrary; it is a result of meticulous research and development by engineers to optimize performance and durability. It strikes an ideal balance between penetration rate, wear resistance, and chip removal, making it a preferred choice for drilling hard materials like rock, concrete, and even metal.

As technology progressed, coal mine tools underwent a transformation. The introduction of pneumatic machines in the 19th century revolutionized coal extraction. Devices like the pneumatic pick, powered by compressed air, significantly increased the speed and efficiency of coal cutting. This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavations This marked a shift from sheer human effort to mechanical assistance, reducing the physical strain on miners and paving the way for more substantial excavationscoal mine tools.

The materials used in drill rod connections also play a vital role in their performance. Typically, these connections are made from high-strength steel alloys that can resist corrosion and withstand the abrasive conditions encountered during drilling. Some advanced connections may also incorporate tungsten carbide inserts or other wear-resistant materials to further enhance their durability.
