China Factory Supply Mining Drill Bits Rock Drilling Tricone Bits For Hard Rock Product Descriptions Tricone bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.

1.Tighten the bits when screw on. 2.When the bit lower down to the bottom , Should give a soft pressure, slow drilling .After a drilling 0.2m-0.3m with appropriate pump, then give the conventional drilling. 3.Drilling could not be without water, if not fear the normal vibration sound or drill too slow, lift the drill to check without delay. 4.When drill jammed, withdraw first, should not to force the rig start. 5.Drill could not without water, to ensure that the bit will be too hot. 6.Use the bits in right order , big size first, then small one . 30*35*40cm 45kg
The used tricone bits are much more cheaper than the new ones because of the cost is low, but the quality is promised. 30*35*40cm 45kg
Company Introduction Our company (Hebei Goldman Petroleum Machinery Co., Ltd.) is located in Hejian City, a historical city nearby Capital Beijing. Hejian city is nearby the well known Huabei Oilfield ,which propelled the establishment and development of Goldman. We specialize ourselves in researching and production of rock drilling bits, mainly including tricone bits, PDC bits, drag bits, HDD hole opener, roller cutters and related tools like drill pipe,rotary slips, and so on. Our products are mainly used for oil well drilling, gas well drilling, geothermal well drilling, mining, geological survey, water well drilling, HDD pipelines projects and foundation projects. Product Detailed Description 1.Cutting Structure The wear-resistance of the teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for the steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit 2.Gauge Structure Multiple gague protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capacity and bearing life. 3.Bearing Structure High precision journal bearing with two thrust faces,Balls lock the cone.Hardfaced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure of the bearing are improved.and suitable for high rotary speed 4.Seal and Lubrication The advanced metal seal package consists of two metal seals and two elastic energizers.Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force,and achieves the bearing seal.In the drilling,metal seals are relatively dynamic,and the energizers are static.This will improve the reliability and durability of bearing seal.The pressure compensator system and advanced grease can greatly increase the lubricating reliability. Our Services (1) We are manufacture can supply good quality goods and competitive price (2) We not only have ourselves design but also can accept customization (3) We have fast and on time delivery time (4) Every bits have it's quality assurance (5) Contact our anytime if you have any question with bits. (6) 24 hours on time reply Contact us All sizes and type can be customized. If you need,welcome to contact me at any time.
What is the feature of 17 1/2tricone drill bit? 1.The strength and wear resistance of inserts are improve by using carbide inserts with high strengthand high wear resistance. 2.Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the load capacity and service life of the bearing. 3.The service life of the bearing is further extended by adopting harder and mort wear resistant material for thrust bearing. 4. Preventing reflux structure has dual function, it can avoid air counterflow and dust entering into bearing when the air-compressor stop working accidentally, and separate air and water in order to avoid water entering into bearing when it works normally to prolong the life of bearing 5.This series oil well rock bit use Sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased. 6.Thrust bearing surfaces are hardfaced and treated with friction reducing technology. 7.This series oil well rock bit use Journal bearing. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improved. What is the superiority of 17 1/2tricone drill bit? 1. It can recycle; it just consume one third of its lifespan in oil exploration process. 2. It can withstand high wob under the conventional drilling rate.
