6-1/4'' IADC622 TCI Trione Drill Bits

TCI Roller Cone Bits
Rock drilling tools manufacturer Bloom offers a complete line of tricone, bicone bit. Tricone drill bits are available in new and used (re-tip and re-run) steel tooth and tungsten carbide insert, size from 3 3/8"(85.7mm) to 26”(660.4mm) for all formations, with any bearingal type, and a full range of additional custom features.

Features:
1. The tricone roller bit working life is according the drilling formation and the drilling rig.
2. Rock formation: Very soft with low compressive strength and high drillability, such as shale, clay, sandstone and conglomerate, etc.
3. Journal bearing. Hard faced bearing surface. Inner hole of cone is silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
4. O ring seal is made of the more wear resistant and high saturated buna-N with the increased seal section and precisely designed scaling flange in the cone sealing area has increased the reliability of the seal.
5. All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.
6. High wear resistance and excellent cutting ability of the insert bit are given full play by using carbide compacts of high strength and high toughness in combination with optimized compact numbers and rows, the exposure height and special shaped compacts. For steel booth bit, the tooth surface is hard faced with new type of wear resistant material and thus has extended working life of the cutting structure while still maintaining high ROP. 

Tricone drill bit include Steel Tooth (also referred to as milled tooth) bits and Tungsten Carbide Insert (TCI) bits, TCI bits are much more durable than Steel Tooth bits, but with a higher cost to manufacture. Both these two groups of Tricone Bits are available with

(1) Open Bearing or Sealed Bearing

(2) Roller Bearing or Friction Bearing (Journal Bearing)

(3) Gage Protected or Non-Gage Protected, etc

Bloom offers heavy duty  bitsAetroleum ndustry number (API Number) and nternational ssociation of rilling ontractor number (IADC number). The IADC number further classifies the tricone bits based on the tooth material of construction, suitability for drilling into soft, medium or hard rock and bearing type used. Bloom can offer rotary drilling toolsfor all possible combinations of IADC number.
