The type of the drilling bit is different according to its usage, the common ones we often use are DTH drilling bit, Rotary tricone drilling bit, PDC oil drilling bit, and drag drilling bit. The DTH drilling bit is attached to the DTH hammer section, and it is very efficient at drilling through rocks and reach to pure water deep in the ground. It is also the most suitable choice for drilling a borehole on a stone for blasting purposes.
The water well drilling rig powers the DTH drilling bit to drill by its hydraulic system and the compressed air from the screw air compressor powers the DTH hammer to make the movements of hitting the stones. When a driller drills a borehole, he needs to take two pieces of equipment to the worksite, a screw air compressor and a hydraulic water well drilling rig, the water well drilling rig will push the DTH drilling bit into the ground and the compressed air from a screw air compressor goes into the DTH hammer, and the DTH hammer hits the rock into the piece through the DTH drilling bit.

The common diameter of the DTH drilling bit is 5’’ (127mm), 6’’ (152mm), 8’’(203mm), 10’’ (254mm), and 12’’ (304mm). The customer can choose the DTH drilling bit sizes according to the requirements, such as what is the diameter of the water pump is most preferred in your local place.

Here is another DTH drilling bit available, it is a casing DTH drilling bit, or you can call it an eccentric DTH drilling bit. It can take the casing into a water well borehole while drilling. This kind of DTH drilling bit is specially designed for protecting the water well wall as the drilling geological condition is soft or easy to collapse during the drilling process.
