14 3/4'' Reverse Circulation Drill Bit, Roller Cone Drill Bit¹

Product DescriptionProduct DescriptionTCI Tricone Drill BitHengji tricone bits are made from high-quality steel and carbide materials for exceptional durability.They feature sealed bearing structures and advanced vacuum oiling technology, ensuring longer bearing life and smoother operation.Designed for performance in various rock formations, our tricone bits deliver reliability and cost-effectiveness for your drilling needs.Tricone  drill bit  featuresTricone bits typically consist of cones, bearings, water passages, and nozzles. The core function is rock breakage through rotation and pressure. The cones are studded with cutting teeth that alternately contact the well bottom, effectively reducing wear and improving drilling efficiency. Tricone bits are classified by the number of cones: single, double, triple, and multiple, with tricone bits being the most common due to their good balance and high drilling efficiency.The bearing system is a crucial component of the bit, typically using rolling or sliding bearings. The bearing inner race mates with the cone shaft, ensuring stability and wear resistance during high-speed rotation. The bit's locking system, including ball locking and thrust bearings, secures the cones and withstands axial loads.Structural FeaturesGauge inserts of high-quality tungsten carbide alloy. Reduce the wear of bit in grinding formations, improve the stability and life of bit.Wear-resistant coating. Carbide wear-resistant material is applied to the palm tip and the edge of the tooth palm, increase wear resistance and life of the bit. Carbide centralizer embedded on the surface of palm. Reduce the wear of bit grinding formations, oblique well and horizontal well, improve the life of bit.Optimize water conservancy structure. Enhance the self-washing.SpecificationHENGJI BIT  SPECIADC CODE 417~837Diameter3 7/8''~32''Bearing Typerubber sealed,metal sealed,composite sealedCirculation TypeMudThread Connection API REG PINNozzlethreePacking & DeliveryPackagingWood Box Packaging: Standard packaging for safe delivery.Fumigation Tray: Used when necessary for international shipping.Custom Packaging: Available based on customer requirements.Delivery Prepared for Delivery: Within 1 week if in stock.Out of Stock: Delivery time depends on order quantity.Transportation Methods: By sea or air.CertificationsServiceCustom Solutions: Tailored to meet specific drilling needs, ensuring the right bit for the job.Global Availability: Our products are available worldwide, ensuring timely delivery for projects of all sizes.Expert Consultation: Our technical team offers ongoing support, assisting with optimal bit selection and maintenance.After-Sales Service: Comprehensive after-sales support, including advice on bit performance and lifecycle management.ApplicationsWater/Oil/Gas Well DrillingHengji tricone bits are commonly used for drilling water, oil, and gas wells. Their ability to handle a wide range of rock formations, from soft to hard, makes them ideal for creating stable and efficient wellbores. Our tricone bits feature advanced bearing systems, including sealed and vacuum-oiled bearings, which enhance durability and ensure extended operational life, especially in harsh environments.Underground Raise Bore Pilot DrillingIn raise boring applications, tricone bits are used for pilot drilling to create shafts for ventilation and ore passes in underground mining. Our tricone bits are engineered to perform efficiently in difficult conditions, ensuring precise and reliable hole creation for raise boring operations. The high-quality materials and advanced manufacturing process we use make DrillMore's bits highly resistant to wear, ensuring a long service life and reduced operating costs.Mining Blast Hole Drillingtricone bits are widely used in mining blast drilling to create holes for explosive charges. They are highly effective in hard rock formations, allowing for quick and efficient penetration. Designed with durable carbide inserts and optimized bearing structures, ensuring reliability even under the most demanding conditions. Our bits are known for their long-lasting performance, reducing downtime and improving productivity in the mining sector.Company ProfileHejian Hengji Bit Manufacture Co.,LTD  is specialized in manufacturing high quality rock bit,especially for tricone bit,PDC bit,hole opener,single cone bit and drag bit.With advanced CNC machines and R&D team and on-time delivery. we have kept our clients ahead of schedule and under budget by providing the highest quality tools at the best possible prices .    We ship to more than 40 different countries and serve industries such as Oil & Gas, water well , Construction,Mining,  Horizontal Directional Drilling (HDD), Geothermal and Environmental.
