HQ diamond bit is the very important part of wireline drilling system. HQ diamond bit is the part directly cut the rock, to penetrate through the different stratum. Relay on the HQ wireline coring system, circulate the rock debris to the surface by drilling fluid,at the same time, retrieve the 36.4 mm column core sample by HQ core sampling tube(commonly HQ inner tube).

The quality of the HQ diamond bits will mostly decide the 59.5mm B size diamond drilling efficiency.

CGEO mainly offer four types of HQ diamond bits:

                                                                                 - HQ Impregnated Diamond Bits(HQ IMP Bit)

                                                                           -HQ Surface Set Diamond Bits(HQ SS Bit)

                                                                   -HQ Polycrystalline Diamond Compact Bits(HQ PDC Bit)

                                                                    -HQ Thermally Stable Diamond Polycrystalline Bits(HQ TSP Bit)

Among diamond bits, CGEO especially concentrates on the impregnated diamond bits. Because the impregnated diamond bit is very complicated, and it is the best choice for most rock formations.

It has best resistance to wear in most rock formations, particularly in fissured and fractured formations. It is less sensitive to abuse, rough handling and improper use.
