API Thread IADC537 IADC637 TCI Tricone Rock Bits Tricone Bits

Product specifications:

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, are widely used in mining, oil well, water well, thermal drilling.

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

SOLLROC Drilling Tools can hard face the milled teeth so that they sharpen themselves while drilling.

Milled tooth tricone bits are designed for very soft to medium hardness formations.

Open Bearing mill tooth Tri-Cone roller cone bit can come with or without gauge protection.

These are less expensive than sealed bearing but they typically do not last as long.

Sealed Bearing mill tooth tri cone bit with or without gauge protection

These are the best preforming and longest lasting style of tri cone on the market.

Guage protection increases the life of the drill bit.
