2 inch rock drill bit

  • 1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

    Another important factor contributing to the rising sales of drilling equipment is the growing emphasis on sustainable practices. As environmental concerns become more pronounced, companies are seeking ways to minimize their ecological footprints while meeting production demands. This demand has led to the development of eco-friendly drilling technologies, such as water-driven rigs and electric-powered drillers that reduce emissions and environmental disruption.

    2). Features:
    1, the drill selects the motor through the high-performance reducer as the reverse power; Use cylinders for propulsion. The hydraulic system is eliminated, so the mechanical efficiency is high, the cost is low, and the performance is stable.2, with anti-card maintenance, when the drill is stuck, the motor is not easy to burn, the reducer is not easy to damage.
    3, simple and easy to move, the weight of the drill machine is less than 500Kg, and can be broken down into three pieces, easy to move and put on the shelf.
    4, the selection of rolling drag plate, the track is not easy to wear.
    5, the drilling machine uses semi-automatic cloud dynamic disassembling drill pipe, high efficiency.
