I. Advantages of Surface Post-Treatment for Cemented Carbide ButtonsDuring drilling operations with Down-the-Hole (DTH) drill bits in high-hardness (rock hardness coefficient f = 14-16 and highly abrasive rock formations, cemented carbide buttons are continuously subjected to severe impact loading, cutting action, and abrasive wear caused by hard rock.Conventional manufacturing processes generally result in carbide buttons with unfavorable surface stress conditions, insufficient surface layer densification, and relatively low fracture toughness. Under continuous cyclic loading, microcracks readily initiate and propagate, leading to failure modes such as button chipping, fracture, and excessive wear, ultimately resulting in premature failure of the DTH drill bit. Frequent bit replacement not only significantly increases consumable costs for mining operations but also adversely affects production continuity and operational efficiency.Unlike conventional approaches that primarily focus on optimizing carbide composition or adjusting sintering parameters, which often provide only limited performance improvements, surface post-treatment technology enhances the microstructure and stress state of the surface layer through mechanical surface plastic deformation. This fundamentally improves the wear resistance and fracture resistance of cemented carbide buttons.The major advantages are as follows:(1) Performance enhancement without changing the substrate materialThe process does not require any modification to the composition of the carbide substrate. Instead, substantial performance improvements are achieved through mechanical strengthening of the surface layer.(2) Optimization of surface stress stateA stable residual compressive stress layer is introduced to effectively offset alternating tensile stresses generated during drilling operations. This suppresses the initiation and propagation of surface microcracks, enhances resistance to fatigue impact, and reduces the risk of brittle fracture under instantaneous impact loading.(3) Increased surface hardness and wear resistanceMechanical strengthening densifies the relatively porous surface structure of the carbide button while refining the carbide grain structure, thereby forming a dense, high-hardness strengthened surface layer with superior wear and erosion resistance.(4) Improved fracture toughness (KIC)Mechanical strengthening repairs original microscopic surface defects, optimizes the surface stress field, and blunts crack tips, effectively inhibiting crack propagation and significantly improving the fracture toughness (KIC) of the cemented carbide buttons.II. Comparative Test1. Test ConditionsThe field test was conducted at a large domestic tungsten-molybdenum mine. The ore body consisted of dense, hard tungsten-molybdenum ore with a rock hardness coefficient of f = 14-16. The formation exhibited excellent integrity and extremely high abrasiveness, representing one of the most demanding drilling environments with severe drill bit wear.        2. Test Results   Cemented Carbide Post-processing:   Standard Cemented Carbide: Compared with standard cemented carbide, post-processed carbide achieves a 10% increase in overall drill bit service life, more stable drilling performance, higher penetration efficiency and 20% reduction in button fracture rate.   III. Conclusion Surface post-treatment technology enhances the surface layer of cemented carbide buttons through mechanical strengthening and plastic deformation, effectively optimizing both their mechanical properties and surface stress state. As a result, the wear resistance and impact toughness of DTH drill bit carbide buttons are fundamentally improved, effectively addressing the primary failure mechanisms of rapid wear and button fracture encountered in high-hardness rock formations.

In the field of bulk material crushing and mineral processing, High-Pressure Grinding Rolls (HPGR) are undoubtedly the "heart" for boosting material comminution efficiency. Nevertheless, when handling high-hardness and highly abrasive ores, severe wear of the roller surface liners has long remained a technical bottleneck plaguing numerous enterprises. Frequent shutdowns for maintenance not only erode production benefits but also drive up operating costs.  To tackle this prevalent industrial challenge, our company proudly launches the TCS series brazed tungsten carbide wear-resistant studs — a premium "bulletproof vest" tailor-made for the repair and strengthening of HPGR roller surfaces. The solution revitalizes your equipment and delivers ultra-long service cycle operation.   I.          Tungstud (Wear and crushing tools) Core Technology: Customized Heavy-Duty Protection Solution Drawing on and optimizing mainstream international wear-resistant technologies, we have carried out comprehensive localization and technical upgrades adapted to the extremely harsh working conditions of high-pressure grinding rolls.   1.      Premium Cemented Carbide: Ultimate Balance of Hardness and Toughness The heads of wear-resistant studs adopt self-developed high-quality WC-Co cemented carbide. Adopting precise formulation and Hot Isostatic Pressing (HIP) sintering process, the material delivers extremely high microhardness. It can well withstand compressive stress generated during HPGR operation and effectively prevent micro-spalling and edge chipping. 2.      Unique Brazing Process: Eliminate Chunk Falling and Fracture The bonding strength of wear-resistant studs determines their service life. We apply advanced high-frequency induction brazing / vacuum brazing technology together with high-strength copper-based filler metal to achieve sound metallurgical bonding between the carbide substrate and steel stud body. The shear strength far exceeds industrial standards, guaranteeing no chunk detachment or fracture even under continuous high impact load. 3.      Scientific Structural Design: Realize Effective "Self-Lining Protection" The overall dimension and taper of the product are precisely calculated for perfect matching with densely distributed holes on HPGR rollers. After the studs are embedded into the roller surface, they efficiently trap fine ore particles to rapidly form a robust material lining between adjacent studs. This dynamic balance of "rock-on-rock grinding" enables nearly zero wear of the roller surface. II.        Crushing and Mixing Tools, Wear and Crushing Tools Application Value: Reduce Costs and Boost Efficiency for Your Production Line Applying the TCS series wear-resistant studs to HPGR roller surface repair delivers tangible economic benefits: 1.      Significantly extended roller service life: Compared with conventional hardfacing repair, roller surfaces restored with cemented carbide wear studs achieve 3–5 times longer service life, supporting thousands of additional hours of heavy-duty operation for the grinding roll. 2.      Lower maintenance and downtime costs: Outstanding wear resistance greatly prolongs maintenance intervals. Traditional roller refurbishment requires 48–72 hours of work. For the same repair area, TCS wear studs cut repair time to only 25% of conventional processes. Benefiting from precision-engineered design, localized damaged sections can be replaced separately rather than scrapping the entire roller, substantially lowering spare parts expenditure. 3.      Stable product particle size & higher throughput: Consistent roller geometry enables the HPGR to maintain steady compression force. This ensures uniform discharge particle size and improves the hourly throughput of the downstream grinding circuit.     III.      Crushing Tools Professional Services: Full-Lifecycle Technical Support We fully recognize that high-quality products represent only half the solution; precise repair procedures are equally critical. Therefore, our company not only supplies premium wear-resistant studs, but also delivers one-stop solutions for roller surface rehabilitation: Roller Surface Condition Assessment: On-site measurement of wear data and analysis of failure causes. Customized Repair Schemes: Offer optimal layout and model selection recommendations according to varying ore hardness and residual roller shell thickness. Welding & Installation Guidance: Assign experienced technicians to provide on-site installation and process guidance to guarantee repair quality. Feel free to contact our technical specialists to discuss the optimal roller surface repair solution tailored to your needs.

With the increasing demand for road infrastructure maintenance in China, urban road repair, highway maintenance, and cold recycling of pavements have placed higher demands on the efficiency, precision, and economy of milling operations. When dealing with high-hardness asphalt mixtures and complex working conditions, challenges such as rapid wear and frequent replacements are often encountered.         The R&D team of Luoyang Goden Egret Engineering Tools developed wear-resistant alloy cutter heads to address the pain points and difficulties encountered in road construction. By adjusting the alloy ratio and using advanced vacuum sintering technology, the hardness and toughness of the alloy are balanced, effectively improving the wear resistance of the alloy, extending the service life of the cutting teeth, and reducing downtime for replacement. The deeply hardened steel tooth body gives it strong impact and bending resistance, effectively preventing breakage and deformation under harsh working conditions and avoiding wear of the tooth base.   Application Cases   In July 2026, product testing was conducted on the expansion and reconstruction project of the Suining-Chongqing Expressway in Sichuan. Compared to products with the same configuration, our G7-2019 had an 18% longer service life than brand Z. Our G8-2220 had approximately a 24% longer service life than brand Z.   The road surface consists of an asphalt overlay and a base layer of asphalt. The asphalt has high hardness, requiring a milling depth of 8-10cm. The aggregate is dense and large-particle, containing pebbles, which causes significant wear on the cutting tool. An XCMG XM2005K milling machine was used.           Comparison of remains:   XTC milling machine: 974 meters, approximately 175 cubic meters. Z brand milling machine: 825 meters, approximately 148 cubic meters.        

Drilling Rods Introduction and Applications Rock drilling tools, including drill bits, drill rods, and shank adapters, are used for blast-holes drilling in rock formations. The drill rod serves as the connecting link between the shank and the bit, transmitting impact energy and rotational torque from the rock drill.  Heavy-duty drill rods are categorized by application into drifting rods, medium- to deep-hole mining rods, surface mining rods, and roof bolting rods.  For jumbo drilling applications, the R32 thread series is the most widely used drifting rod type, employed in tunnel drifting and underground excavation projects to drill blast holes with diameters ranging from 43 to 51 mm. Rod lengths are available from 3,700 mm to 6,400 mm. The rock tools for Hydraulic jumbo are classified by the thread model on the bit-end connection. Given that blast-hole diameters typically range between 41mm and 51 mm, the diameter at the bit-end connection must be kept below 32 mm. With the continuous advancement in hydraulic rock drill performance—particularly higher impact power and increased output torque—the reduced cross-section at the thread root on the bit-end connection to match with the top hammer bits has become the weakest point of the rod body. To enhance material strength, the industry has introduced the α250, α280, and α330 thread series, along with the SR32, SR35, and SR38 series, as well as the TC35 and TC42 series. XTC Luoyang offers a comprehensive drilling rods range, manufactured with high-quality alloy steel, advanced carburizing heat treatment, and precision machining technology. The rods deliver consistent product quality, extended service life, and proven performance in mining operations across multiple regions, contributing effectively to cost reduction and efficiency improvement for customers.

Coal mining picks are one of the main consumables in coal mining machines. With the advancement of intelligent, high-yield, and efficient coal mining, the proportion of hard coal seams and gangue-containing composite coal seams being mined continues to increase. Coal picks are subjected to high-frequency impacts, abrasive wear, alternating loads, and high-temperature friction. Frequent replacement not only interrupts continuous production but also significantly increases consumable costs and underground operational safety risks, directly restricting mining efficiency and increasing the cost per ton of coal produced.   The main failure modes of coal mining bits are as follows: 1. Abrasive wear: The tooth tip becomes blunt, the alloy head wears down, and the cutting ability is lost.   2. Impact fracture: Impact from gangue causes the carbide head to chip and crack; alternating loads generate fatigue cracks in the tooth body, leading to tooth shank fracture.   3. Weld failure: Insufficient brazing strength causes the entire alloy head to detach; impact cracking leads to the entire carbide head detaching.   4. Thermal fatigue failure: Cutting friction generates instantaneous high temperatures, and spray cooling causes repeated thermal expansion and contraction, resulting in a network of microcracks on the tooth head, accelerating the wear and fracture process.   To address the aforementioned issues, Luoyang Golden Egret has focused its research on upgrading materials, innovating processes, and improving structures to enhance the overall performance of cutting teeth in terms of wear resistance, impact resistance, and fatigue resistance.     Luoyang Golden Egret balances hardness and toughness by adjusting the tungsten-cobalt ratio in its alloy teeth. For soft coal seams and hard coal seams with intercalation of gangue, they use gradient cobalt-containing cemented carbides and WC powders with different grain sizes to prepare cemented carbides, improving strength while maintaining hardness. RS1 high-strength alloy steel is selected as the base material for the tooth body and forged. Simultaneously, a composite heat treatment process is employed to enhance the fatigue resistance of the tooth body and significantly reduce fatigue fracture.   Luoyang Golden Egret Coal Minig Picks Application Case   In a coal mine in Jincheng, Shanxi Province, Luoyang Golden Egret and Manufacturer K conducted comparative tests on U95 coal mining cutting picks. After on-site comparison underground, the consumption ratios of the two specifications of cutting picks from Luoyang Golden Egret and Manufacturer K were 1:8 and 1:1.8, respectively. Overall, the consumption of our company's cutting picks was lower, and the customer recognized the effectiveness of our products.     Mining Face Operating Information Total length 124 frames (approximately 210 meters), mining height approximately 3.5 meters. Frames 70-84 consist of gangue and large interbedded rocks (blue sandstone, high hardness and strong abrasiveness), the remainder being coal seams. Equipment Brand and Drum Type Tiandi 1650 Coal Mining Machine Diameter: 2.24 meters, single drum can hold 54 cutting teeth, 24 cutting teeth are installed on the inner ring of the drum.

Top hammer bits are core rock-breaking components widely used in mining and tunnel excavation. During operation, they are continuously subjected to high-frequency impact, alternating stress and severe abrasive wear. Their service life, structural strength and operational safety are highly dependent on precise control of the heat treatment process for the rock drilling tools. Deviations in heat treatment parameters will easily lead to abnormal metallographic structures, degraded mechanical properties and premature fracture failure. Our company implements standardized and refined full-process heat treatment management to consistently guarantee the in-service performance of products. 1. Pre-Heat Treatment Preparation  1.1 Raw Material Inspection High-quality alloy steel complying with relevant standards is adopted for drill bit blanks. Strict inspection is conducted on material specifications to ensure the base material meets the requirements for high-strength rock-breaking working conditions. 2. Post-Forging Pre-Treatment All forged drill bits undergo annealing to eliminate forging residual stress, refine internal structures and improve machinability, laying a solid foundation for subsequent machining and formal heat treatment. 3. Surface Cleaning Before furnace loading, all oil stains, oxide scales and impurities on work-piece surfaces are thoroughly removed to prevent surface defects during heating and ensure stable heat treatment quality. 4. Structural Optimization for Stress Relief Stress concentration tends to occur at water holes, flushing grooves and sharp corners of drill bits, which are high-risk areas for quenching cracks. In the machining phase, we optimize structural designs by replacing sharp right angles with circular arc transitions. Fine grinding is applied to special-shaped parts such as water holes and flushing grooves to relieve local stress and enhance overall structural reliability.  2. Control of Heat Treatment Equipment and Core Processes  We adopt vacuum heat treatment equipment and customized precision processes to achieve stable and controllable performance of top hammer drill bits.  2.1. Vacuum Furnace Heat Treatment Heating is performed in a full vacuum environment to effectively avoid surface oxidation and decarburization, ensuring uniform and stable surface performance and metallographic structure of drill bits. 2.2 Precision Temperature-Controlled Quenching Quenching temperatures are strictly matched in accordance with steel grades to avoid coarse grains and uneven structures, so as to ensure qualified overall mechanical properties of finished products. 2.3. Gradual Preheating Process A staged preheating method is applied with a properly regulated heating rate to reduce thermal stress and effectively prevent cracking and deformation of work-pieces. 2.4. Size-Based Programmable Temperature Control Exclusive heat treatment programs are configured for drill bits of different sizes and structures. This ensures synchronous and uniform temperature distribution between the surface and core of work-pieces, and eliminates incomplete quenching and inconsistent product performance.  3. Full-Process Quality Inspection & Control A dual inspection system covering raw materials and finished products is established to realize traceable quality control across all working procedures.  3.1. Incoming Raw Material Testing Prior to warehousing, strict tests are carried out on key indicators including chemical composition, non-metallic inclusions and grain size to prevent unqualified base materials from entering production. 3.2. Sampling Inspection of Finished Products Regular sampling tests are conducted on heat-treated finished products to verify core performance indicators such as hardness, metallographic structure and impact toughness, guaranteeing stable quality and compliant performance of all product batches. Supported by this complete set of standardized heat treatment management systems, our threaded drill bits deliver excellent impact resistance, wear resistance and structural stability. We have developed differentiated heat treatment processes tailored for tunnel engineering and iron ore mining to adapt to various harsh operating conditions. Our high-reliability top hammer drill bits help ensure safe, efficient production for mining and tunnel construction projects.

During rock drilling, drill rods are subjected to complex alternating stresses caused by impact, torsion, bending and other loads. The surface of the rod body suffers severe abrasion from rocks, while the central bore undergoes impact and corrosion by mine water, leading to complex failure behaviors. As a consumable for rock drilling, the quality of R32 drill rods has a substantial impact on mine production costs. Hence, stabilizing and improving the manufacturing quality of drill rods is of great importance. I. Main Failure Modes of R32 Drill Rod The primary failure modes of R32 drill rods fall into three categories: thread wear failure (see Figure 1), fracture failure at the transition zone between threads and rod body (see Figure 2), and rod body failure (see Figure 3, a less common case).                Figure 1                Figure 2                 Figure 3 II. Quality Problem Analysis of R32 Drill Rod 1. Material defects of hollow steel used for R32 drill rods. 2. Defects including poor straightness and low dimensional accuracy of the rod body. 3. Unreasonable structural design of drill rod end faces and non‑standard processing, resulting in poor fitting between adjacent drill rod end faces. 4. Deficiencies in the design or processing of transition zones, which lead to low precision of threads, thread roots and transition zones, surface scratches, and high stress concentration in transition zones. 5. Poor transition fit between wave‑shaped threads and transition arcs, leading to stress concentration. 6. After heat treatment, the microstructure and hardness of the drill rod’s surface layer and core fail to meet specifications, resulting in inferior comprehensive mechanical properties. 7. Restricted by equipment limitations, surface treatments such as shot blasting and anti‑corrosion treatment cannot be implemented, which compromises the overall mechanical performance of drill rods. III. Measures to Improve the Quality of R32 Drill Rods 1. Rod Body Structure The structural form of end faces and transition grooves is a vital factor influencing the quality and service life of drill rods. Strictly designing and machining end faces and transition grooves in compliance with standards is an effective way to prevent premature fracture of R32 drill rods. 2. Machining Process Controlling rod body straightness and standardizing the machining of thread end face structures as well as internal and external end‑face chamfers are primary measures to guarantee drill rod service life.The depth of transition grooves and the radius of curvature at groove bottoms exert the greatest impact on the stress concentration factor and must be strictly regulated. Besides, the fullness of wave‑shaped threads is also a major determinant of service life; wave‑shaped threads with insufficient fullness have small volume and wear quickly. 3. Heat Treatment Process The common heat treatment process for R32 drill rods is carburizing + air cooling + tempering. As a chemical heat treatment technique, carburizing enables specific elements in the atmosphere to infiltrate the steel surface through heating and thermal insulation, modifying the chemical composition of the surface layer and creating distinct microstructures and mechanical properties between the core and surface layer. During carburization, higher temperature, carbon potential and carburizing speed accelerate the carburizing process, while lower parameters slow it down. Excessively high carbon content in the carburized layer produces network carbides, increasing brittleness and notch sensitivity. After quenching, coarse martensite and excessive austenite form; surface austenite in the carburized layer impairs the surface hardness and wear resistance of drill rods. Accordingly, the proper selection of carburizing and heat treatment parameters is the most critical factor affecting drill rod quality. 4. Shot Blasting and Anti‑Corrosion Treatment Shot blasting and anti‑corrosion treatment are among the key measures to improve rock hammer drill rod quality, as they significantly extend fatigue life and are indispensable procedures. At present, few domestic manufacturers conduct surface treatment for drill rods, which is a major reason for the substantial quality gap between domestic and foreign drill rods. IV. Conclusion XTC rock drilling tools enforce strict control over key production links including machining, heat treatment and surface treatment to ensure manufacturing quality. Our goal is to provide customers with highly wear‑resistant, impact‑resistant and long‑service‑life rock drilling tools, contributing to the efficient development of the global mining industry.

The cutter body utilizes independently developed high-strength alloy tool steel, combined with superior heat treatment processes, resulting in industry-leading strength and toughness, effectively coping with high ground pressure and highly abrasive environments.   • Spark-Free Series (Advanced Testing Type): Developed for high-risk environments such as gas outburst mines, these tools, through a special material formula design, effectively prevent spark generation during impact, ensuring safe production.   A mine in Ningxia demonstrates firsthand: From "15 teeth per cut" to "only 4 teeth per cut"   No matter how advanced the theory, nothing is more convincing than concrete, real-world data. Previously, a large coal mine in Ningxia encountered a severe "tooth consumption problem" with its coal mining machines when facing hard rock formations. Ordinary cutting teeth wear out extremely quickly, requiring an average of 15 teeth to be replaced for every cut of coal, resulting in monthly tooth procurement costs exceeding 500,000 yuan. Even more troublesome was the frequent downtime for replacements, which severely impacted the mine's uptime and coal production.   After introducing Luoyang Golden Egret 35 alloy ceramic cutting teeth, the mine's operational data underwent a dramatic transformation. Under the same operating conditions, now only 32 cutting teeth are needed for 8 cuts of coal, averaging just 4 per cut. The benefits of this change are astonishing: it not only significantly reduced spare parts procurement costs but also completely solved the problem of frequent downtime caused by tooth replacements, significantly improving single-shift operating efficiency and coal output, truly achieving "cost reduction and efficiency improvement."   Conclusion   A good cutting tool determines the success or failure of a production line.

XTC Crushing Tools Launches a New Generation of Composite-Reinforced Tungsten Carbide Plate — Cast Substrate + Hardfacing Wear Layer + Carbide Studs, Solving the “Impact Resistance + Wear Resistance” Challenge Recently, our company Products for Crushing &Mixing has made significant progress in its R&D project on wear pats for crushing equipment. The new generation of composite-reinforced crusher tooth plates has been successfully trial-produced and has entered the batch verification stage under real-world operating conditions. Specifically developed for high-impact, high-wear environments such as mining, metallurgy, building materials, and solid waste processing, this product utilizes a composite manufacturing technology combining a “high-toughness cast substrate + surface hardfacing wear layer + carbide stud reinforcement.” This achieves comprehensive improvements in impact resistance, wear resistance, and service life.  As a core consumable parts for crushers, the Tungsten Carbide Overlay Plates is subjected to repeated impact from large materials, strong compression, and abrasive wear over long periods of operation. Its performance directly affects equipment throughput, maintenance intervals, and the customer’s total operating cost. Traditional tooth plates made of a single material generally struggle to balance toughness and wear resistance, often leading to cracking, rapid wear, and tooth tip failure. To address these industry pain points, our R&D team has successfully developed a multi-layer composite-reinforced tooth plate structure through long-term research. Substrate MaterialThe new product uses a high-strength, high-toughness alloy cast steel, achieving a tensile strength of ≥850 MPa, yield strength of ≥650 MPa, and impact toughness (AKV, room temperature) of ≥35 J/cm², with hardness is HB280–320. By optimizing the casting process and heat treatment, the internal density and overall load-bearing capacity have been significantly improved. This allows the tooth plate to maintain excellent stability under continuous impact from large ores, effectively reducing the risk of fracture, chipping, and spalling.   Wear ReinforcementUsing advanced automated hardfacing technology, a high-hardness wear-resistant layer is applied to the main wear areas of the tooth plate. The hardfacing layer achieves a hardness of HRC 58–63, a single-layer thickness of 4–8 mm, and a bond strength of ≥350 MPa, offering excellent resistance to abrasive wear and scouring. Laboratory abrasion tests show that the wear life of the hardfaced area is 2–3 times longer than that of conventional high-manganese steel tooth plates. Moreover, through post-weld stress relief and gradient transition design, the hardfacing layer remains resistant to spalling and cracking under high-impact loads.   Carbide Stud ReinforcementAt the critical crushing Tools areas, the company has innovatively applied brazed carbide stud reinforcement technology to upgrade the tooth tips. The studs are made of high-performance tungsten-cobalt cemented carbide, with a hardness of HRA 88–90, bending strength of ≥2200 MPa, and compressive strength of ≥4000 MPa. Using a high-strength brazing process, the studs are firmly bonded to the tooth plate body, significantly improving the cutting and crushing efficiency of the tooth tips and reducing rounding and dulling. In practical applications, the service life of the tooth tip area is expected to increase by more than three times. Validation ResultsBased on simulated operating conditions and preliminary field verification, the comprehensive service life of the new generation composite-reinforced tooth plate is 80%–200% longer than that of conventional cast steel tooth plates. The replacement interval for a single set of tooth plates is significantly extended, and equipment downtime for maintenance is reduced by over 30%. This effectively helps customers lower consumable costs per ton of ore and improve continuous equipment operation efficiency. Commitment to Innovation Going forward, we will continue to respond to customer needs in real-world operating conditions, advancing upgrades to our series of products including crusher tooth plates, toothed rollers, and wear-resistant liners. With higher product performance standards, more advanced manufacturing processes, and a better service system, we aim to help industry customers achieve efficient, safe, and stable production.  

Down-the-hole (DTH) drilling technology stands as one of the most critical innovations in modern rock drilling engineering. As the core component of the entire drilling system, DTH drill bits directly determine drilling efficiency, service life, project cost and construction safety. DTH drill bits connect with DTH hammers through precision spline structures. During high-speed drilling, they bear strong alternating impact loads from the hammer piston, continuous rotating torque and severe friction from rock particles. This harsh working environment puts forward extremely strict requirements on material performance, structural design and manufacturing process: the bit body must have high strength and fatigue resistance, and the carbide teeth must have excellent impact toughness and wear resistance to ensure stable operation under complex geological conditions. In recent years, breakthroughs in tungsten carbide sintering technology have promoted the emergence of ultra-coarse grain and nano-grain carbide materials. These new materials perfectly balance high toughness and high wear resistance, break through the performance bottleneck of traditional carbide teeth, and greatly expand the application scope of DTH drill bits in extreme working conditions.
