TCI bits series

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 bothconical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure desigh, combined with maximum cone offset,result in high bit penetration rates. The deep intermesh of cutter rows prevents bits bailing in sticky formations.

517   Medium Formation TCI Tricone Bits

The 517 features aggressive chisel tungsten carbide insert 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 HAN rubber O-ring provides adequate sealing for bearing durability.

617  Medium-Hard Formation TCI Tricone Bits

The 617 features robust chisel tunsten carbide inserts on the heel row and conical on the inner   rows.  This design provide a fast drilling rate and added cutting structure durability in medium  to medium hard formations.  The HSN rubber O-riprovides adequate sealing for bearing  durability.

637 Hard Formation TCI Tricone Bits

The 637 bits can be used drill hard and abrasive forma-tions. Ware-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bits gauge.maxmum numbers of hemisphercal-shaped inserts are used in all rows to provide cutter durability and long life.

114-117  Soft Formation Tooth Bits

The 114-117bits 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-resistant hard facing is used to control tooth wear.Onthe softest bit types this hard facing completely covers the bit teeth.

127   Medium-Hard Formation Tooth Bits

The 127bits are 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

About The Tricone Bit

1) High-strength,high flexibility,high temperature,high wear resistance.

2) High-precision metal seal.

3) locking roller ball,to adapt to high-speed.

4) The use of high strength hig toughness carbide teeth.

5) Hours in the rotary cone bit with the impact,crushing and shearing the role of broken rock.

6) cone bit to adapt to the soft,medium and hard of various strata.

7) Reasonable price and long working life.

Feature: Diamonds are impregnated in the matrix behind the PDC cutters.

Benefit : Increased footage drilled in abrasive applications.

Feature :pdc bit are arger than standard TFA.
