Steel tooth bits used to drill through soft rock formations, such as chalk or limestone, are longer, more slender and more widely separated than the teeth for hard rock formations, such as granite. Steel tooth bits are also known as milled bits, even when a manufacturer used a forging process to create the cutting wheels.

Drill-It’s Steel Tooth Tri-cone Bits are forged with the highest quality steel and and features a new formula and process of high-quality tungsten carbide and special conical spherical inserted teeth, which can break hard to very hard strata rocks more effectively and can withstand drilling under high drilling pressure.

The trimming teeth at the cutter tips and the gauge protection teeth on the cutter back can protect the drill bit more effectively, make the borehole more regular, and prolong the service life of the drill bit.

It also features high precision plain bearings with two thrust surfaces, ball lock mechanism, with bearing surfaces inlaid with wear resistant alloy and silver plated. It has excellent wear resistance and is suitable for high-speed rotation during drilling.

Accompanied with high-quality HNBR rubber seals that are wear-resistant and high-temperature resistant, which will increase the reliability and durability of the bearing seals during the drilling process. The compensating seal system and high-quality grease allow to limit the pressure difference, greatly improving the lubrication reliability and protecting the bearing mechanism.

Our Steeltooth Tricone Bits

At Drill-it we strive for the best, and would be unhappy with anything less and we hope our customers feel the same. Thats why our steeltooth tricone drill bits are just that and more.

Strong, durable, with high rates of penetratrion and a long life, these bits are perfect for all kinds of senarios.

The go-to solution for well digging from simple water wells to industrial scale oil Field applications. The main benefit of using a Tricone is that you can make it and design it to work for you. Each Tricone has its own IADC code which changes and varies based on ground formations i.e. IADC code 1.1.1 will be a Steel Toothed Tricone used in soft formations

Selecting The Right Bit

Please refer to the following graphs to establish if the bit you are purchasing is right for the job.. The following graphs demonstrate what series of core drill bit and what drill bit profile would be appropriate for differing rock formations.

IADC Codes

IADC codes are a standardized way to classify and describe tricone (or rotary) drill bits used in the drilling industry. These codes help drilling professionals identify the specific type of tricone bit they need for a particular drilling application. The IADC code typically consists of four characters and provides information about the bit's design, cutting structure, and bearing/seal system.

  1. First Character (Formation Type)
  2. Second Character (Bit Profile)
  3. Third Character (Bit Type)
  4. Fourth Character (Additional Features and Special Designations)

For example, an IADC code like "537" might indicate a tricone bit designed for drilling in very hard formations (5), with a TCI bit profile (3), featuring sealed roller bearings (7).
