14 3/4inch Milled Tooth Tricone Bit IADC 127

Product Discription


Milled tooth Tricone Rock Drill Bits:

  1. The milled tooth (steel tooth) tricone bits drilling for soft to medium rock formation.
  2. The medium formation milled tooth tricone bits are used to drill high compressive strength, medium rock formation. Shoot projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.
  3. The soft formation milled tooth tricone bits are used to drill low compressive strength, soft formation. Long projection tooth lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear resistance hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.
Cone Size 14 3/4"
Bearing Type Elastomer Sealed Bearing

Application Soft formation with low compressive strength ,and high drill ability, such as mudstone, gypsum, salt, soft limestone, etc.


Main features


1. Cutting Structure of this type sealed and non-sealed TCI tricone bits :

The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for steel tooth bit.


2. Gauge Structure of this type TCI tricone rock bits :

Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hard-facing on the shirttail increases gauge holding capability and bearing life.


3. Bearing Structure of this type TCI tricone rock bits :

High precision roller bearing with two thrust faces. Ball lock the cone. Thrust faces hard-face with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.




Tricone bits , hole openers can be used to explore /drill gas/oil/geothermal/water wells. 3 7/8”~26” are available for Tricone bits. 4 1/2”~17 1/2” are available for Diamond PDC bits.


The TCI Tricone Bit ranges in size from 3.875” (88.9mm) to 28” (711.2mm)
