The impregnated diamond core bit has emerged as the most commonly used type in the mineral exploration industry. Our impregnated Diamond Core Bit performance is the product of many years of research, coordinating diamond grading and selection technology, bit design, matrix composition and manufacturing processes with extensive testing under a very wide range of drilling conditions. The result- Our impregnated core bit can be designed and produced to give the best performance and economic results under any specified drilling conditions.


We manufactures the impregnated diamond core bits series range of impregnated diamond matriceswith matrix layer metal bonds that range from hard, abrasion resistant types to soft, ductile types.


In general, a hard, abrasion resistant matrix such as the“GS2” or “GS4” would be used to drill a  soft, abrasive, unconsolidated formation while a soft, ductile matrix such as the GS10” or “GS12”and “GS14” would be used to drill an extremely hard, non-abrasive, consolidated formation.

The “GS6”,”GS7”,”GS8” “GS9” are used for the medium hardness formation. The idea is to match the bit matrix hardness to the formation hardness in order that the metal bond of the matrix layer will erode at a controlled rate during normal drilling operation. This controlled erosion of the matrix layer metal bond will in turn continually expose new layers of sharp synthetic diamonds until the matrix layer of the bit crown is totally consumed. The matrix hardness of “GS” series are selected according to the colors.

In addition, we manufacture the new technology matrix formula of the impregnated core bits. We also offers high performance GH-Series range of impregnated diamond matrices. For the very hard formation, we can supply the impregnate turbo type and gear type diamond core bits for you. They have the more high performance for drilling.

They are AQ, BQ, BQ3, NQ, NQ2, NQ3, NQTT, HQ, HQ3, HQTT, PQ, PQ3, PQTT, T2 series, T6 series, DCDMA standard, European standard of 412, HWF, PWF, GEO S BORE, AW, BW, NW, PW, HWT, PWT, BQ rod shoe, NQ rod shoe, HQ rod shoe, BTW, NTW, NMLC, HMLC, TNW, LTK 48, LTK 60, AWT, AXT, NWD4 and over-sized bits.
