Our line of rotary drilling tooling and supplies includes tricone bits, pdc bits,

claw bits, drag bits,HDD rock reamer, and hole opener, and much more.

Prod rill Products offers a complete line of tricone, bicone and reverse circulation

bits. Tricone 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 use in all formations,

with any bearing/seal type, and a wide range of additional custom features.

Tricone bit Included Steel Tooth (also referred to as milled tooth) bits and

Tungsten Carbide Insert (TCI) bits, TCI bits are much more durable than Steel Tooth

ones, but carry 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

All ProDrill tricone bits the above are manufactured according to strict standards

set forth by the American Petroleum Institute (API).

Tricones and PDC Bits are classified according to characteristics set forth by the

International Association of Drilling Contractors (IADC).

Tricone bit, are widely used in mining, oil well, water well, thermal drilling
