Custom Drill Bit

The upper part of the bit body is a threaded connection core tube, the side of the bit body is provided with a water tank, and the bottom lip surface is also provided with a water nozzle. Both the sink and the nozzle ensure the circulation of the rinsing liquid, which eliminates the role of rock powder and cooling the Drill Bit. In order to increase the clearance when drilling the clay layer and the shale formation, the ribs are welded to the inner and outer sidewalls of the hard alloy drill bit, which is called a rib type drill. A needle-shaped carbide self-grinding drill can be used for a hard layer having high abrasiveness. Generally, hard alloy drill bits are drilled into rock formations of grade II-VII; needle-shaped carbide drills can be drilled into VI-VIII grade rock.
