ChaiTools R&D the Solid Carbide Drilling Tools With Tungsten Carbide.
Carbide drilling tools is a kind of drill bit used in core drilling. The steel cylindrical drill body is named after the carbide cutting tool inlaid with tungsten carbide. The shape of the cemented carbide cutting tool and the number of inserts on the drill, the arrangement, and the angle of inserts are different, which are called the bottom edge, the inner edge and the outer edge, so as to ensure there is a gap for water and powder discharge. The upper part of the drill bit body is connected with the core pipe by the thread, the side part of the drill bit body is provided with a water groove, and the bottom lip surface is also provided with a water outlet. Both the water tank and the water outlet ensure the circulation of the flushing liquid, so as to remove the rock powder and cool the drill bit. In order to increase the clearance when drilling into clay layers and shale formations, ribs are welded on the inner and outer walls of the cemented carbide bit, which is called a rib-type bit. Needle carbide self-grinding drills can be used in hard formations with high abrasiveness. Generally, carbide drill bits can drill into formations with grades II to VII; needle-shaped carbide drills can drill into rocks of grades VI to VIII.
