Drt reverse circulation drill bit suppliers in south africa
Reverse circulation drill bit is a key component in reverse circulation drilling technology, which is widely used in geological drilling, mine rescue, engineering construction and other fields. The main feature of reverse circulation drilling technology is that the flushing medium (such as water, mud, or air) rises at a high speed in the center hole of the drill rod, effectively removing drilling debris and improving drilling efficiency.
Drt reverse circulation drill bits is made by quality tungsten carbide tips and steel with forging process, Combining the hardness and the high impact toughness of the steel makes the drt revest circulate DTH drill bit widely used in hard formation drilling, especially in the water well drilling, mining and rock drilling. Except for DTH hammer bit, we also supply thread button bits, retrac button bit, taper button bits, drill rods, shank adapters, coupling sleeve etc drilling tools.
Working principle of reverse circulation drill bit
In reverse circulation drilling, the drill bit is connected to the power device through the drill string, and the power device drives the drill string and drill bit to rotate for drilling. At the same time, the flushing medium flows downwards from the wellhead through the annular space between the drill pipe and the hole wall or between the inner and outer pipes of the double walled drill pipe, and then returns to the surface from the drill pipe or the inner pipe of the double walled drill pipe after reaching the bottom of the hole, forming a reverse circulation. During this process, the water holes or special designs on the drill bit allow the flushing medium to flow back smoothly, carrying the drill cuttings back to the surface.
Advantages of reverse circulation drill bit
Strong slag discharge capacity: Due to the high-speed rise of the flushing medium in the center hole of the drill rod, drilling cuttings are easily carried to the surface, reducing the phenomenon of repeated crushing at the bottom of the hole and improving drilling efficiency.
Small disturbance to the borehole wall: During the reverse circulation drilling process, the flushing medium has a relatively small flushing effect on the borehole wall, which is beneficial for drilling stability and reduces accidents such as buried drilling and broken drill rods inside the borehole.
Water saving drilling: When air is used as the circulating medium, water-saving drilling can be achieved, especially suitable for construction in arid and water scarce areas.
