Frequently Asked Questions
What is a DTH hammer bit?
DTH hammer drill bits are made with quality alloy steel and precision machined, used in drill rigs for penetrating various rock formations. Down-the-hole hammers are drilling tools attached to a drill string and drilled into a bore to help break up tough rock through quick penetration.
What is the IADC Code, and how do you read it?
The International Association of Drilling Contractors devised a system to describe any tricone bit through a simple four-digit number. This streamlines the process of ordering a new tricone bit and reduces confusion for drillers everywhere.
The IADC classification system dedicates the first three digits to the design and function of the tricone, with the final digit being an alphabetical code for any additional features of the bit. Here is how to read an IADC Code properly:
|1||STEEL TOOTH BITS for Soft Formation STEEL|
|2||TOOTH BITS for Medium Formation|
|3||STEEL TOOTH BITS for Hard Formation|
|4||TUNGSTEN CARBIDE INSERT BITS
For varying formation hardness with 4 being the softest and 8 the hardest.
|1||1, 2, 3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest.|
|Third Digit||BEARING / SEAL TYPE|
|1||Standard open bearing roller bit|
|2||Standard open bearing roller bit, air-cooled|
|3||Standard open bearing roller bit with gauge protection which is defined as carbide inserts in the heel of the cone|
|4||Sealed roller bearing bit|
|5||Sealed roller bearing bit with gauge protection|
|6||Journal sealed bearing bit|
|7||Journal sealed bearing bit with gauge protection|
|Fourth Digit||ADDITIONAL FEATURES|
|S||Standard Steel Tooth|
|G||Extra Gage Protection|
|Z||Other Insert Shape|
The first digit represents the hardness of the rock formation for which the drilling tool buttons are best suited. The tool is assigned a number between one and eight, indicating the type of rock the teeth or buttons of a drilling tool are designed for:
If the first digit is a 1, 2, or 3, this indicates a steel tooth where 1 is engineered for soft rock formations, 2 for medium formations, and 3 for hard formations. If the first digit is a 4, 5, 6, 7, or 8, this indicates a tungsten carbide insert (TCI). 4 represents softer formations, with 8 representing the hardest formations.
The second digit represents further rock formation information. 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 formation hardness.
The third digit represents the bearing type of the drilling tool. For example, Tricone bits use different bearings depending on the type of material to be drilled. A 1 stands for standard roller bearings, 2 is for air-cooled bearings, and 3 is for open bearings with gauge protection. A 4 or 5 represents sealed roller bearings, with 4 being standard sealed roller bearings and 5 being a sealed roller bearing with gauge protection.
The numbers 6 and 7 represent sealed journal bearings, with 6 being a standard sealed journal bearing and 7 being a sealed journal bearing with gauge protection.
The fourth digit of the IADC Code is a letter indicating the special properties of the drilling tool.
