For many years, our company contributes all heart to the Chinese drilling industry, has become the leader of the realm. Our company presents first rate management, designing, manufacturing and after sales service of drilling bits and tools. As specialists in the drilling realm, it is our commitment to provide customers with the highest quality, low price, up-to-date drilling bits and tools. Whatever your requirements in specialized large diameter shaft drilling, you can rely on the total capabilities of the King-drilling Engineering Science & Techniques Limited Company(Langfang). Now, our products have been widely used abroad in foundation engineering drilling realm, and form many series. Roller Cutters and Large Diameter Roller Cutter Bits In large diameter drilling industry, roller cutter bit is the most useful and effective tool for drilling in hard rock formation. Our company have developed 6-series,8-series,12-series,15-series and 17-series roller cutters with either TCI tooth or welding-tooth or milled tooth. All king-drill roller cutters have long life with metal seal design. King-drill bit bodies are available in diameters from φ700-φ5000mm. TCI cutter TCI cutter bit cutters in batches for export TCI cutter bit for export welding teeth cutter welding teeth cutter bit Roller Cone Bit and Large Diameter Assembled Roller Cone Bits Our company provide φ76-φ660 tri-cone bits with either TCI or milled tooth. All these bits are long life and low price. At same time we developed king-drill series large diameter assembled roller cone bits. The bits are available in diameters from φ345-φ1200mm. 2800 assembled roller cone bit assembled roller cone bit roller cone bits assembled cone bits in batches Belling Tools for Piling Foundation We can design and manufacture any belling tools for any formation, any rig and any parameters, provide one to one service. roller cone belling tool soil belling tool soil belling tool rock belling tool for big rig 2500 rock belling tool No-circulation Drilling Tools for Hydraulic Rotary Drill Rig Along to the spring up of hydraulic rotary drill rig, we developed no-circulation drilling tools series, to match various rigs, such as Bauer, Mait, Sany and all others. We design and manufacture more than 1000 tools every year, the manufacture technology keep ahead in China. NO-circulation drilling tools include drilling buckets, drilling augers and core barrels. Drilling bucket Soil and rock drilling buckets are available in diameter φ600-φ3000mm. The bucket bottom can be single bottom or double bottom. Single bottom bucket is used for drilling clay formation; double bottom bucket is used for drilling other formation. And the bottom can be one eyed or two eyed. One eyed bottom is fit for drilling small diameter sand or scree formation, but two eyed bottom is fit for big diameter scree or boulder formation. The bucket teeth can be flat teeth for drilling in soft formation; flat teeth and round shank chisels for drilling in soft to median rocks; round shank chisels for drilling in no-weathered rocks. bucket for rock bucket for soil buckets for sending out bucket for claypan Soil and rock drilling augers Soil and rock drilling augers are available in diameterφ600-φ2500mm, including different configurations –single cut/single flight, double cut /double flight, flat teeth cut and round shank chisels tapered cut. rock auger bit soil auger bit Core barrels Core barrels are special tools which can remove a core, only cut an annular groove so that penetrating rate increased, cooperate with augers and buckets. Core barrels are available in diameterφ600-φ3000mm, with flat teeth for soft soils, round chisels for median rock and roller bit for hard rock. 2500 roller cone core barrel R-chisels core barrel Drilling teeth At same time, our company provides all series of drilling teeth. All these drilling teeth have excellent quality. drilling teeth round chisels seat Down-hole Reverse Circulation Drilling System for Hydraulic Rotary Drill Rig Technics illustration Down-hole reverse circulation drilling system is designed to cut rocks with strength exceeding 100Mpa. The system can be used for core drilling or full section drilling. There are two methods to select: down hole air-lift reverse circulation system and down hole water-power reverse circulation system. In condition of steady well wall or using casing protection, air-lift reverse circulation system is used; but in condition of unsteady well wall and no casing using, water power reverse circulation system is good choice. Now, our company keep ahead in rock drilling techniques in the world. air lift circulation roller core bit air swivel air lift circulation drilling air lift circulation full section cutter bit PDC Bits and Small Diameter Drag Bits Our company design, manufacture and sale small diameter grab bits. Excellent steel material, excellent tungsten carbide, excellent foundry and heat treatment techniques make drag bit long life. We also deal in PDC bits in diameter from φ91-φ311. three type drag bits PDC bits Chevron drag bit Reamer Bits for Oil, Water and Mine Well Drilling Our company have abundant manufacture experiences in reamer bits and tools for oil well, water well and mine well drilling industry. The gauge, stabilization, penetrate rate and life all achieve first level in national and international drilling realm. For example ,we have developed 157-φ244.5 and φ157-φ310.9 roller cone reamer bits for Chinese Continental Science Drilling engineering, and made excellent contribution to CCSD because of excellent quality and low price. reamer bit for CCSD reamer bits for CCSD in batches reamer bit for coal mine big diameter roller cone reamer bit drag reamer bit Reaming Tools for Rock Trenchless or Minisized Tunnel Drilling Industry To satisfy the demands of national and international trenchless and city minisized tunnel drilling industry, we developed rock trenchless reamer bits and tunnel drilling cutters. All these bits and tools have excellent quality and cheap price, and have been abroad applied in the country and out of the country. minisized tunnel bit minisized tunnel cutters minisized tunnel cutters II trenchless cutter trenchless drilling bit trenchless drilling cutter bit trenchless drilling cone bits Engineering Drilling Pipe and Other Tools Our company can design and manufacture various drilling pipes ,casing and other tools. All these production have excellent quality and cheap price. Casing drill tools for SMW long auger drill pipe rotate joint flange drill pipe
