Geodrilling Bits Mfr. (GBM)
|Geo Drilling Bits Mfr. specializes in the production of high quality diamond core drilling tools for mining exploration drill consumables and diamond core drilling (wireline core and double-tube core drilling). All our products (impregnated core bits, surface set bits, impregnated reaming shells, surface set reaming shells, PDC core bits, PDC non coring bits, impregnated casing shoe bits, surface set casing shoes, core lifters, core lifter cases, locking couplings, adaptor couplings, stabilizers) are made by ourselves. As the biggest manufacturer of diamond core bits (including the impregnated and surface set), reaming shells (including the impregnated and surface set), PDC bits and exploration drilling tools in China for ten years, we can provide all the products to satisfy our customer's requirements for exploration drilling. Based on "win-win" relationship and long-term respect, we are able to supply a complete set of wireline and double-tube drilling equipment. We have the advantage of providing the most competitive quality and most timely services. We do our best to fabricate ordered items as soon as purchase orders are received. We promise the most satisfactory products, the best and timely service in wireline core drilling exploration and all drilling projects.

|Impregnated Diamond Core Bits
Geo Drilling Bits premium series of impregnated diamond core bits are ideally suited to modern drilling conditions. The impregnated core bits are wireline series and double-tube series (including AQ, BQ, NQ, HQ, PQ, BQ3, NQ3, HQ3, PQ3, NQ2, BWG, NWG, HWG, BWF, NWF, HWF, T2 56, T2 66, T2 76, T2 86, T2 101, T6 86, T6 101, T6 116, T6 131, T6 146 etc.). All matrixes of the impregnated core bits are suitable for rock formations with a choice of soft to very hard matrices. They are especially good in fractured, abrasive or silicified rock. Matrix hardness is specified by our colour system, which is designed to help you match the most effective impregnated diamond core bits to your application. Before ordering, refer to Matrix Selection Guide, Bit Wear and Crown Shapes of the impregnated core bits. In particular, the gear type impregnated diamond core bits are designed and developed by ourselves. They are suitable for the following materials: ironstone, quartzite, taconite, rhyolite, silicious stone, streak quartzite, marble and jasperite, and for non-abrasive or dense soft stones and very hard stones.
|Surface-set Core Bits
Natural diamond surface-set core bits, designed for core drilling in soft, medium-hard, hard-formation, the specified formula structure, the stone sizing and bit geometry will ensure maximum cutting efficiency. Over several years, we have manufactured several types of surface-set bits for exploration drilling in any rock using wireline and double-tube core barrels. The tapered step crown design of the surface set provides good stability, while the big water hole crown is designed for soft and loose rock (especially NQ3, HQ3 and PQ3).
The casing shoe is effective in applications ranging from very abrasive, lighting fractured formation to loose conglomerates or overburden. 1. hard matrix of the casing shoe bits is durable for use in changing formations with both high and low thrust drilling; 2. medium-hard matrix of the casing shoe bits for use in moderately abrasive and fractured formation.
- Size from AW , BW , NW , HW , PW , SW (the casing shoe bits include NQ , HQ , PQ drilling rod casing shoe bits);
- Crown of the casing shoe bits: flat and "V" type, and other types needed by customers;
- Natural diamond set-surface and impregnated diamond casing shoe bits.
Using quality natural diamonds set in a very resistant matrix, the natural diamonds sections are accurately cast into the matrix of the reaming shells and become an integral part of the shell. It ensures maximum performance as the reaming shell will maintain a full gauge hole in all types of ground. Reaming shells include standard reamers, backend reamers and other lengths of AQ, BQ, NQ, HQ, PQ, T2 56, T2 66, T2 76, T2 86, T2 101, T6 86, T6 101, T6 131, T6 146 (available to your reaming shell specifications). Also, we improve the carbide locking couplings (two rings) which can protect and stabilize the wireline core barrel.
These Include PDC, PCD and natural diamond non-coring bits. PCD and natural diamond noncoring bits are normally used in all large geological projects (such as hydroelectricity) and exploration drilling. They are designed for drilling/grouting rather than core drilling.
|PDC Core Bits
These consist of a purpose designed cast matrix head to which PDC inserts have been fixed in a pattern. PDC bits have proved successful in soft to medium hard consolidated formations. PDC core bits are used in coal mining exploration and for opening hole drilling exploration.
Standard size of the PDC bits: AQ, BQ, NQ, HQ, PQ, BQ3, NQ3, HQ3, PQ3, NQ2, T2 76, T2 86, T2 101, T6 86, T6 101, T6 131, T6 146.
Barrel assemblies: carbide locking coupling, adapter coupling, inner tube stabilizer, core lifter, core lifter case, stop ring, landing shoulder, landing ring and so on.
