9 7/8" IADC 215 Tricone Bits with Steel Milled Teeth
Rock drilling tools manufacturer ProDrill provides a full range of rotary drilling tools such as tricone bit & bicone bits. Tricone bits are available in new and used (re-tip and re-run) steel teeth(ST) and tungsten carbide insert(TCI), size from 3 3/8"(85.7mm) to 26"(660.4mm) for use in all formations, with any bearing/seal type, and provide a wide range of additional custom features.
ProDrill offers heavy duty Steel tricone drill bits to meet your customized needs. We have classified the bits based on their diameter (footprint), American Petroleum Industry number (API Number) and International Association of Drilling Contractor 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. ProDrill manufactures tricone bits for all possible combinations of IADC numbers.
Tricone drill bits include Steel Teeth (or milled teeth) bits and Tungsten Carbide Insert (TCI) bits, TCI drilling bits are much more durable than Steel Teeth bits, but come 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.
Tricone drill bits are widely used in mining, oil well, water well, thermal drilling.
Tricone Roller Bit break rocks by applying axial force and rotational torque to the drill bit through the rotation and pressure mechanism of the drilling rig. The rotation of the drill bit drives the roller cone to roll. Under the action of axial static load and dynamic load when the roller cone rotates, the roller cone drill bit will crush the rock through different actions such as crushing, impact, shearing and scraping.
The single-cone drill bit (palm plate) has the same structure as the tri-cone drill bit, but the palm plate has an added straight shank welding or straight shank detachable structure, which is installed on large-diameter rotary drilling cone combination drill bits or to form non-excavation cone reamer products.
Main steel grades for roller cone drill bit bodies: 15-20Ni4Mo, 24SiMnNi2CrMo, 15MnNi4Mo.
Geological drill bits, as important tools in geological exploration and engineering construction, integrate a variety of advanced technologies and play a crucial role in resource development and infrastructure construction. The main steel grades used for drill bit bodies are: 35CrMo and 42CrMo.
