U-YOUNG Internatioal Trade Co., Ltd is one of the main manufacturers of geological diamond drilling tools in China. Excellent design, sophisticated furnace and CNC lathe, experts in powder metallurgy, strict quality control, has enabled U-YOUNG to manufacture all range of matrix to achieve the demand of every day drilling. U-YOUNG is capable of designing and manufacturing diamond core bits, reaming shells, exploring drilling tools, also can make special products to the customer specifications. We try our best to provide competitive return-on-invest for most customers. 1. Impregnated Core Bit Impregnated diamond drill bits are designed to perform as grinders. Diamonds are embedded in an sintered matrix. The matrix erodes away at the same rate as the diamonds become worn and rounded. Thus new sharp diamonds are exposed to continue cutting through the rock. Surface set diamond bits can be used with any type of core barrels. By varying the diamond grade, size, quality, and matrix hardness and crown shapes, the users can satisfactorily drill and core hard and homogeneous formations. To avoid excessive matrix wear at the leading edge of each segment, tungsten carbide inserts are fitted on each side of the water way. This kind of bits cannot be used in broken or loose formations. U-YOUNG surface set bits have proven to have a high penetration rate, long service life, and best adaptability to change formation. 4. Impregnated Reaming Shell Diamond reaming shells are important tools to be used together with bits. Its main funtions are maintaining bore-hole gage, improving drill string stability and protecting lower drill string from excessive wear. U-YOUNG Impregnated reaming shell provides high quality systhetical diamond and PCD pins,wearproof matrix, good fluids passage. Therefore its service life is long, its reamer and penetration rate is high. Reaming shells are available for all types of core barrels and drill bits 5. Surface set reaming Shell Standard U-YOUNG surface set reaming shell set with specially selected diamonds and PCD pins, facilitate effective flushing and contribute to long service life and good drilling economy for both reaming shells and drill bits.
