Long life of the drill bit: Since the wear ratio of the diamond composite sheet as the cutting tooth is 20-40 times higher than that of the cemented carbide, it is more than 10 times that of the ordinary diamond drill bit, so the service life is greatly prolonged;2, the drilling efficiency is high: the diamond exposure is large (the composite polycrystalline layer is almost completely exposed), the drill bit can always keep sharp, thus greatly improving the footage speed;3, can be low pressure, low speed drilling: the drill bit is scraped and sheared to crush the rock, and the drilling pressure is only about 1/3 of the same diameter diamond impregnated drill bit;4, good diameter-keeping effect: the inside and outside of the composite drill bit can be set with diamond polycrystalline diameter, strong wear resistance, good diameter-keeping performance, and can make efficient use of cutting teeth.5, a wide range of use: Practice has proved that the drill bit is suitable for the drilling of carbonate, limestone, white rock, clay rock, siltstone, sandstone and other soft, medium-hard (rockable below 9 grade rock formation) strata. Compared with the general drill bit, especially the rock formation of 6-8 grades, the effect is particularly significant;6. Due to the fast drilling speed and long service life, the number of starting and lower drilling is small, the drilling cost is greatly reduced,Cost-effective. Specification model:You can use 50 drill rods or 42 drill rods or 60 drill rods.
