8 1/2" IADC Code 127 Tricone Bit with Steel Milled Teeth. Tricone drill bits have two types, Steel Teeth (or milled teeth) bits and Tungsten Carbide Insert (TCI) bits, TCI drilling bits are much more durable than Steel Teeth bits, but carry a higher cost to manufacture. Both these two groups of Tricone Bits are available with
IADC Codes - Tricone Rock Bits. IADC Codes make it easier for drillers to describe what kind of rock bit they are looking for to the supplier. Bit Brokers International follows the IADC bit classification system in which the first three digits classify the bit according to the formation it is designed to drill and the bearing/seal design used.
teeth, can be a normal wear characteristic of tung-sten carbide insert (TCI) bits and does not necessar-ily indicate problems in bit application or operating practices. Broken teeth, however, are not considered a normal wearing condition for steel tooth bits. For those, it may indicate either improper bit application or operating practices.
Tricone rotary bits are sometimes a good alternative to a DTH hammer. Available in TCI (carbide buttons) and mill tooth configurations. We carry a large inventory of rerun bits and can also supply new bits. TCI bits are available for Medium Soft, Medium Hard, and Hard formations.
These bits mainly fall into two classes depending on the manufacture of the cutting elements or "teeth". Steel-tooth bits have cones that have wedge-shaped teeth milled directly in the cone steel itself. Extremely hard tungsten carbide material is often applied to the surfaces of the teeth by a welding process to improve durability.

Milling bits, also called milling machine tools and bits, are shank- or arbor-mounted cutters that can shape a variety of workpieces. End mills are designed to remove material and create multi-dimensional shapes and profiles. Some function similar to a drill bit and can plunge into a workpiece vertically.
To be effective, hard facing must be resistant to loss of material by flaking, chipping, and bond failure with the bit. Hard facing provides wear protection on the lower (shirttail) area of all roller-cone bit legs and as a cutting structure material on milled-tooth bits (Fig. 8).
Apr 05, 2017· ROLLING CUTTER BITS • Milled Tooth Bit (Steel Tooth) – Long teeth for soft formations – Shorter teeth for harder formations – Cone off-set in soft-formation bit results in scraping gouging action – Self-sharpening teeth by using hard-facing on one side – High drilling rates - …
A Milled-Tooth Bit is a type of a rolling cutter bit that has tooth cutters made up of steel which have been assembled as the parts of bit cone. This bit is rotated to gouge or cut out the formations. Every bit has a different kind of teeth based on the rock formation. It may use inserts build-up of diamond or tungsten carbide on its gauge.
Regardless of tooth type, the second digit takes into account all factors of the bit and ranks the rock formations the drilling tool is best suited for on a scale from 1 to 4. 1 represents soft formations going up to 4 representing the hardest formations.
