Renqiu Dream Bit Co., Ltd.

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. Application Fast delivery factory tricone drill bit for various mining stone,rock with high quality tungsten carbide insert Our drill bits are widely used in mining, oil, gas, water well drilling, HDD, quarrying and construction. Company Information Hunan TianYing Drilling Machine Manufacturing Co., Ltd. was founded in 1958, located at Zhuzhou, China, the word famous tungsten Carbide production base.

1, the classification: drilling, exploration, oil, drill, and drilling accessories 2, the product name: 215.9 mm 8 1/2 inches £¬rubber sealing disc bit three 3, product introduction: H series bit for O form rubber sealing sliding bearing drill bit, in a routine use can withstand high speed drilling of pressure. 4, its main structure features: 1) using high strength and high toughness cemented carbide gear, improve the shock resistance ability of teeth, reduce the broken teeth rate 2) the optimization of the tooth row number, gear, toothy height and unique alloy tooth shape, give full play to the drill bit cutting ability and the cutting speed 3) the card spring lock, able to bear high disc drilling pressure 4) die hole with gold, and improve the welding minus integration of the bearing capacity of bite 5) using high saturated acrylonitrile-butadiene rubber sealing ring, optimization of o-type seal compression quantity and improve the reliability of the bearing seal 6) can limit the pressure difference and prevent drilling fluid into the lubrication system of the rubber oil storage sac, for bearing system provides good lubrication, and to ensure that "O" type sealing ring, improve the normal work bit working life 7) with 250 ¡æ high temperature resistance, low wear new, improving the drill bit sealing grease lubrication system high temperature resistant ability. According to the customer request.

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.
