PDC bit is Polycrystalline Diamond Compact bit ,it also named Diamond bit. According to the Material Classification： Matrix body PDC bit: It was made by tungsten carbide powder,and gauge protection is TSP. Steel body PDC bit: AISI 4145H heat treatment steel (America standard steel ), High quality CNC machines milling pockets, blade, nozzles. According to the Applicable Industry Classification: Mining Industry There are some 3blade PDC bit mainly used for mining industry in Australia ,and Russia .The formation is very soft . Choosing Steel body PDC bit can saving more drilling cost. Water well drilling Various used for geothermal well drilling ,PDC bit have higher ROP. Oil & Gas drilling It is the most widely used bit in the field of Oil &Gas drilling. Hydraulic factors are very important to the bit during drilling. PDC bit have been used in areas that were previously unavailable, such as harder, more abrasive, and more variable formations. This expansion into the new field has a great impact on the balance between the diamond (fixed cutter bit) bit and Tricone bit. The PDC bit is mainly composed of the bit body, cutting teeth, nozzles, gauge protection and API Thread connection. Great bits design and manufacture a wide variety of Matrix body PDC bit and Steel body PDC bit. Our PDC bits are offered in a variety of sizes, blade count and cutter sizes.

Great bits design and manufacture a wide variety of Matrix body PDC (polycrystalline diamond cutter) bits. Our 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. The Junk Slot Area of the bit water hole can be designed according to the hydraulic parameters required by the drilling process. The shape of the Matrix body PDC bit can be designed according to the formation characteristics to achieve the best use effect. PDC bits are designed for high speed drilling in shale, limestone, and sandstone formations. Unlike roller cone bits , these PDC bits are a 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. Main Advantages of Matrix Body PDC Bit: Working on the cutting (shearing) principle, the energy consumption of rock breaking is low. PDC composite sheet has super hardness, wear resistance and self sharpness. PDC bit is a fixed tooth bit, no moving parts, high reliability GREAT Matrix Body PDC Bit Advantages: Force balanced, resist impact to the blade during high-speed drilling, to make bit work stable. Plus wear knot section, reduce collision in the high-speed rotational vibration. Patented matrix formulation, extended bit life. Optimal hydraulic design, easy to move out the drill cuttings and cooling. Equipped with back reaming Cutters. The cutter is high performance to increase the ability of anti-impact and anti- abrasive We are here to provide you with a unique and custom solution for your specific drilling needs; from design and manufacturing to service in the field. We have what you need. We are one of the best drill bit manufacturers in china,we produce Great Drill Bits,welcome to buy it.

Overview of Hybrid Drill Bit Hybrid drills bits are compounded by the PDC fixed cutting and the roller free cutting structure. The teeth on the cone crush the rock by impact crushing, forming broken pits at the bottom of the well, and making the bottom of the well uneven. It can weaken the strength of the bottom rock. The auxiliary function of the cone facilitates the PDC tooth to enter the formation, which is more beneficial to the PDC tooth scraping and cutting rock. Developed a personalized composite drill bit series for complex hard-to-drill formations, which has strong formation adaptability in difficult-drilling formations such as hard formation abrasive formations, tight mud shale, and heterogeneous formations such as conglomerate formations. High rock breaking efficiency and fast drilling speed. Hybrid drills bits produced by GREAT combine PDC and cone drill technology for smoother drilling, better torque management, and precise maneuverability. The great brand of hybrid drills is a superior directional drill for motor and rotary applications, offering higher cumulative speed capability, damped torque response and precise steering capability on a variety of bottom hole assemblies. The Advantage of Hybrid Drill Bit PDC is matched with cone optimization, and the drill bit has strong adaptability and high rock-breaking efficiency in hard-drilling strata. The hybrid bit utilizes the cutting advantages of PDCs soft formations and the rock breaking strength and stability of roller cones in hard or intercalated formations, with the potential to maintain a higher total rate of penetration (ROP) than an older cone or PDC single bit over a larger range of footage. The balance analysis and optimization of the composite cutting structure balance the working stability of the drill bit with the adaptability of the formation and improves the service life. Computational fluid dynamics (CFD) optimization analysis of bit watercourse and nozzle to improve flow field distribution and cleaning cooling effect. Cangzhou Great Drill Bits Co.,Ltd. is a drill bit factory,we will give you the best service.

Overview of Drag Bit Drag bit are manufactured from forged high-quality alloy steel and hard alloy, plus state of art welding technology and multiple precision heat treatment to provide the highest penetration rate and longest lifespan at the roughest condition. A drag bit is usually designed for soft formations such as sand, clay or some soft rock. However, they will not work well in coarse gravel or hard rock formations. Uses include drilling water wells, mining, geothermal, environmental and exploration drilling. Whenever possible, they should be used to drill pilot holes because they produce cuttings that are easiest to log. Three-wing bits tend to drill faster, whereas four-wing bits are longer-lasting, more durable, and drill a straighter hole. The Details of Drag Bit The Advantage of Drag Bit The blade system allows you to replace worn or damaged individual blades rather than the entire bit. The cost of purchasing multiple blade types and sizes is much lower than the unit. Prepare a variety of blades to ensure your time on site is most effective. The drag bit is suitable for the formation with low hardness and high plasticity. From 3 7/8" three-step bits to 6 1/4" four-step bits to the various sized chevron bits, this replaceable blade system offers high-quality carbide-tipped wings that weld onto your pipe or threads are cost-effective and versatile. GREAT also produces and sells various drill bits for oil fields, mines, geological surveys, hydrology exploration, engineering piling, geothermal development, Wells and other applications. At the same time, we will provide specific solutions according to customer requirements and actual drilling conditions We provide bits of rock,types of drag bits,drag bit drilling and Great Drill Bits,RFQ today.

This type of firewood is dried in a kiln, which bakes the wood and forces out the moisture, making it ready to be used immediately after purchase or delivery. The process of kiln drying our wood ensures it is insect-free and weighs less than other kinds of firewood. Also, Kiln Dried Firewood is a cleaner burning firewood. It ignites easily and burns hotter and more efficiently than other types of wood. With less creosote buildup, it leaves very little ash or soot in your fireplace or fire pit, which is a win-win all around. Species................Mixed hardwood species Dimensions.............Split logs, averaging 200mm in length Contaminants...........Contamination-fre , e Smoke..................Producing very little smoke
