Product Description

Product Description

Our tricone bit is from high manganese steel and carbide, can be used for geological prospecting, development of oil and gas, drilling water wells,blast holes and making holes for seismic prospecting,construction engineering. Now there are eleven common types of tricone rock bits.

Normal IADC:

437 Soft Formation TCI Tricone Bits:

The 437 TCI bits are used to drill low compressive strength, very soft formations. 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.

517Medium 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 formation. The HSN rubber O-ring provides adequate sealing for bearing durability.

637Hard Formation TCI Tricone Bits:

The 637 bits can be used to drill hard and abrasive formation. 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.

617Medium-Hard Formation TCI Tricone Bits:

The 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-ring provides adequate sealing for bearing durability.

Our Advantages

Apply to oil well ,gas well, Construction, Water Drilling, Mining, Horizontal Directional Drilling, Geothermal and Environ-mental. Tricone bits are used in general to drill a wide variety of rocks, from soft to extremely hard, while PDC bits can drill various sorts of formations, especially at harsh environments.
This is just part of the content. Do you want to know more about it? Please contact our customer service,tell your needs, you will hear the most professional reply!

Please select the applicable formation and parameters according to the instructions. Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate. Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously. Bottom hole must be clean and bit must not be used for long section reaming. Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures The bit should be kept indoor with dry and well ventilated conditions at 10-33ºC and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.
