1. I am Bella Qiao at your service at any time:

Hejian Smart Petroleum Machinery Co., Ltd. was founded in 1998, located in the center of North China and Beijing open highway, Cang Shi Highway, the road adjacent to Beijing and Tianjin Shi, Beijing-Kowloon railway, Beijing-o-rail from the left and right after. South of the capital170 km, 110 km to Tianjin, North China Pearl Baiyangdian 35 km, excellent location and convenient transportation, a favorable convenient conditions for our development.We mainly specializes in Tricone Bits. TCI Rock Bits,Steel Tooth Tricone Bits,PDC Bits, PDC Drag Bits, PDC Core Bits, Single Bits, Bits Cones for oil,water and mining drilling.The material all tungsten carbide or high carbon steel, And the quality in accord with API and ISO standards.

TCI tricone  bits for Mining and Rock Drilling
The strength and wear resistance of inserts are improve by using carbide inserts with high strength

and high wear resistance.
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.
The service life of the bearing is further extended by adopting harder and mort wear resistant material for thrust bearing.
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.
TCI tricone bits for Oil Drilling
Inserted tricon bits
1. This series tricone bit use Sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.
2. Thrust bearing surfaces are hardfaced and treated with friction reducing technology.
3. Ball locked cone, suitable for high rotary speed.
TCI Tricone bits
1 This series tricone 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.
2. O ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.
3. The bit bearing can be ball locked
4. For steel tooth bit, the tooth surface is hardfaced with new type of wear resistan
Material and thus extended working life of the cutting structure while still maintaining high ROP. 5..Main Availability

 The IADC code introduction of TCI tricone bits

tricone bit Cutting structure: very long widely spaced ,chisel-shaped inserts and considerable cone axis offset against center line of bit ensure very high penetration rate .To secure the bit from diameter loss, the gage protection inserts have got shorter length and greater angle of the top. Formations: long intervals of very soft poorly compacted shales ,sandstone, clays, salts and soft li mestones. Size and IADC available: 3 3/4" to 26" IADC 415,435,445,417,437,517,537,617

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 bothconical 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 for mations the HSN rubber o-ring provides adequate sealing for bearing durability.

TCI 637 can be used to drill hard and abrasive forma-tions .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.

TCI 617 the tci 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 .

Steel tooth bit

The 114-117 soft formation tooth bits are used to drill low-compressive strength ,soft formations long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistent hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.

The 127 medium – hard formation tooth bits

Used to drill high-compressive strength medium hard formations   short projection teeth with reduced crest length are used in this series of bit designs durable hard facing is applied to reduce tooth wear.

Milled tooth bit specializes in designing, manufacturing, marketing and serving the high performance diamond bits and drilling tools used in petroleum industry .The company is established by the top experts of the field ,and equipped with advanced equipments and facilities .Our diamond bits named Great, which ranging from 3"to 17-1/2".All the products have been awarded the ISO9001 certificate.Furthermore, the experienced and knowledgeable service team will ensure all the superior performance of our products in both the domestic and international market.With our service pursuit "Drilling requirement initially ,Customer satisfaction finally ",we assure the products the best quality by adopting advanced design technology ,manufacturing process and strict quality control .Our company will always improve and innovate to satisfy different needs for all users in the entire world
