GREAT

The Steel body PDC bit body is made of AISI 4145H round steel. The cost of Steel body PDC bit is lower than that of Matrix body PDC bit.

Every Steel body bit shall have heat treatment, to improve the mechanical properties of steel, to eliminate residual stress and improve the cutting performance. 

Each blade surface shall be welded with hardened material to increase wear resistance and erosion resistance.

Most of our raw material is made in the USA and France. Our supplier technical engineers come to our factory training our welder and have a meeting to show their new products regularly. We communicate with our supplier very well and are very happy. So if our customers need, we can ask our engineer to have a meeting with each other face to face. And Every bit has its own tracking card and serial number. For any of our bits shipment to the field, you can provide the serial number, then we will check what kind of cutters we use in the steel body PDC bit and what about the design. 

GREAT, as one of the professional drill bit manufacturers in China,  we design and manufacture a wide variety of Matrix body PDC (polycrystalline diamond cutter) bits. Our matrix PDC bits are offered in a variety of sizes, blade count and cutter sizes. The Matrix body PDC bit is sintered with tungsten carbide powder. Gauge protection with natural diamond.Tungsten carbide matrix can resist erosion, wear resistance, high strength and good effect of diameter control.

This kind of PDC bit is designed for high-speed drilling in shale, limestone, and sandstone formations. Unlike roller cone bits, these PDC bits are one-piece matrix bodies with no moving parts. The fixed-cutters shave away the rock, making it possible to operate with higher rotation speeds more efficiently in consolidated formations.

This type of Bi-center bit mainly used for medium to medium-hard compressive and abrasive formation, it has medium and high-density parabolic crown and heavy cutters density for the bit has good impact resistance and anti-abrasive, high wear-resistant diamond gauge, the bi-center drill bit has a longer service life. In directional applications, Bi-centre bit performance usually presents performance challenges in terms of efficiency.   

We designed this bi-center bits with close attention to hydraulic optimization to improve chip removal and ensure effective tool cooling. In addition to the improved hydraulic configuration, the cutting configuration was carefully studied to ensure that it is both effective and balanced - not only on conventional components but also when used in combination with a bent-case motor. This design concept of bi center bitscombined with GREAT's wide range of PDC cutters grades and geometries results in a bi-center drill with excellent drilling performance.

GREAT customized made Diamond core bits, which include Matrix body PDC bit and Steel body PDC bit, the Diamond core bit is used to drill an underground core (or mineral core) primarily when samples of underground rock (minerals) are required.

• Every PDC Core bit is optimized hydraulically for each cutting structure and formation application.
• Each design is based on a balanced and fully covered cutting structure.

The PDC Core bit has designed a shallow parabolic profile and medium cutter density for coring the medium hard formation. Nozzles options according to the hydraulic request, it is installing the size of the mainly PDC cutter is 1308mm, and the most popular blade is 6 blades,  7 blades,  8 blades,  to enhance the rock core drill bits' ability to drill in hard formations. Special TSP gauge or PDC Arc-cutters to protect the diameter.

• The superior patented tool testing method provides the best PDC cutter for any challenge.
• Soft to medium-hard formation with low compressive strength interbedded with hard layers. 
• Cab be used for different rock types: Mudstone, limestone, anhydrite.

Polycrystalline Diamond Composite (PDC) core bits were originally designed for oil drilling. The surface of the cylindrical PDC cutters consists of high-quality synthetic diamond particles sintered together by high pressure and temperature. The PDC core bits have high tool hardness, wear resistance and toughness, and the bits are widely used in oil, gas, mining and engineering drilling fields.

  RC PDC drill bit from GREAT are manufactured from AISI 4145H heat-treated steel. Reverse circulation drill bits are widely used in geological exploration samples, oil wells, mining, and other fields. The reverse circulation drilling method combined with RC drill bit and hammer is the preferred drilling method for initial exploration, ore body development, and other exploration drilling. By completing the drilling project objectives within the budget, reverse circulation drilling with RC bit provides a more cost-effective drilling method. 

The raw material of GREAT's RC diamond PDC bit is heat-treated steel and has a strict inspection tracking report.

Unlike the traditional center flush circulation, our Reverse Circulation PDC Bits save a lot of fuel and other operating-related costs.

Reverse circulation drilling can obtain preliminary geological data before analyzing cuttings samples and investing in detailed geological data for exploration coring plans. Reverse circulation is also faster than coring, which means drilling more holes. 

We design RC PDC drill bit according to customer requirements and formation conditions. As one of the most trusted drill bit manufacturers in China, GREAT has professional staff and precise equipment to get the best drill bits for customers.

Reverse Circulation Drill Bits price varies based on material and type. The cost of the reverse circulation drill bit （rc drill bit）is an important part of the equipment in order to increase efficiency and quality of use, which is why you cannot compromise on their quality. All reverse circulation bits are submitted to strict quality control by GREAT to ensure that you always get maximum satisfaction. Contact us to get a quotation on a custom rc bit.
