advantage

1)soft with low compressive strength ,such as soft marl ,clay, unconsolidated sand-storm ,salt or hard shale,ect.

2)The world's latest sealing technology ,ensure the bearing is more effcient ,and more suitable for drilling at high rotary speed and high tem-perature working condition.

3)Bits bear is enhanced treatment ,and prolonging the bit working life,reducing the drilling cost.

detailedinformation

1. Tricone bit cutting structure
Adopting new formula of new technology of the high quality hard alloy tooth, enhance the cutting teeth mechanical properties.
2. Tricone bit diameter structure
Using multiple gage protection structure: Die with multidrug trimming tooth (GT teeth), round back, claw back set have cemented carbide gear, surfacing resistance mo alloy, strengthen ZhaoJian and anterior apply welding, greatly improving the drill gage protection ability.
3. Tricone bit bearing structure
Adopting high precision with radial sliding, two way thrust bearings, ball tight. Tooth claw big shaft neck and two stop surface welding have wear-resisting alloy, cone big hole and two stop surface solution and silver inlaid special alloy, increase the abrasion resistance and resistance bearing vice occlusive ability, improve bearing ability of high speed vice adapt.
4. Tricone bit seal lubricants
Adopting advanced metal seal, greatly extend the drill life.
5. Tricone bit applicable
Metal seal bit stable performance, than common rubber seal bit longer life, suitable for underground power drill and high penetration rate turntable drilling.

We are HeJian tengda Drill Bit Manufacturing Co.LTD. Was established in August 18, 2001, from a simple bit processing, gradually developed into a research and development with independent research and development, design, production capacity, production, trade type enterprise.Company continuously introduced international advanced production equipment and production technology, wide social elite, and employ more people of  engaging  in cone bit, diamond bit of research and development, manufacturing for more than ten years of professional senior technical engineers team, to continuously upgrade its products.The company's operating philosophy is "quality first, customer first" we believe that the product has no best, only better, only by constantly improve the quality of their products to win customer recognition, can be in an impregnable position in the intense market competition.
