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

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.

Product Description: 215.9mm IADC137 Industrial standard:SY/T5164 Payment terms: T/T,Western Union,and L/C are acceptable Applications:Medium hard with high compressive strength and high abrasiveness, such as limestone, dolomite, sandstone and chert, etc. Note:other size and IADC is available

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.

Product Description: 1. Bit Breakers The Bit Breakers are suitable to make up or break out the drilling bit during the oil well drilling and repairing operations. The Users should be chosen the bit breaker according to the size and model of the drilling bit. Feature:Improve support and retention Advantage:Manage the magnitude cutter loading and bit torque Benefit:Improved bit durability and directional responsiveness Advantage:Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allow for higher flow rates with minimal increase in pump pressure. 2. Detailed introduction to Bit breaker 1) Bit breaker is mainly used to screw on or off a rock bit to the bottom of drill string. 2) It can also prevent the rock bit from dropping into well hole. 3) The price of it is cheap and the use of it is safety and reliable. 4) It is easy to operate. First, the bit breaker is placed on well hole and then put the rock bit onto it. Turn it to screw on or off the bit by turnplate.

TCI 437 Soft formation TCI Tricone bits The 437 tci bits are used to drill low compressive strength very soft formation tci bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design combined with maximum cone offset ,results in high bit penetration rates.the deep intermesh of cutter rows prevents bit bailing in sticky formations. TCI 517 medium formation TCI Tricone bits The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows this design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations the HSN rubber o-ring provides adequate sealing for bearing durability. TCI 617 TCI tricone bits 617 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows .this design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations . the HSN rubber o-rin provides adequate sealing for bearing durability . TCI 637 can be used to drill hard and abrasive formations wear –resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.
