In the mining industrial, blast hole drilling is very important to achieving the required product or outcome. Drilling suitable holes allowing explosive charges to be placed down the holes. And then to blast large areas making them more manageable and easier to remove.
Blast Hole Drill Bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.
