Functions and features, long drill life, using diamond composite as the main cutting teeth, its service life is more than times that of cemented carbide, and ~ times that of ordinary diamond drill bits
, high drilling efficiency, diamond exposure Large quantity (almost all of the composite polycrystalline layer is exposed). The drill bit can always remain sharp, thus greatly increasing the footage rate
. The drill bit can drill at low pressure and low speed to break rocks by scraping and shearing, and its weight on bit only needs Diamond impregnated drill bits with the same diameter have a bit weight / left and right
and good diameter protection effects. Our company's composite disc drill bits can be inlaid with diamond polycrystalline diameter protection inside and outside. They have strong wear resistance and good diameter protection performance, which can make the cutting teeth highly efficient. Utilization
Wide range of applications. Practice has proven that this drill bit is suitable for drilling in carbonate rock, limestone, chalk, claystone, siltstone, sandstone and other soft and medium hard (rock formations below the drillability level) Compared with ordinary drill bits, the drilling effect is particularly significant, especially in drilling-level rock formations
Due to the fast drilling speed and long life, the number of drilling and drilling operations is less, and the drilling cost is greatly reduced, which has the advantages of Cost-effective.
The drill bit is welded by a composite piece and a steel body, so the water outlet design can be freely controlled. The outer diameter of the steel can be increased with protective alloy, extending the service life of the drill bit while improving drilling efficiency
