API customized drill bits IADC126 5 1/4 inches (133mm) for hard rock
Product Description
Wholesale API milled tooth sealed tricone roller cones bits in the stock based on the lowest price and excellent quality from China factory
Bit Description:
IADC: 126 - Steel tooth journal sealed bearing bit for soft formations with low compressive strength and high drillability.
Compressive Strength:
0 - 35 MPA
0 - 5,000 PSI
Ground Description:
Very soft, unstratified, poorly compacted rocks such as poorly compacted clays and sandstones, marl limestones, salts, gypsum, and hard coals.
We can offer mill tooth and TCI tricone drill bits in a variety of sizes (from 3 7/8” to 26”) and most of IADC Codes.
Depending on the cutting material, tri-cone bits can be divided into TCI bits and steel tooth bits.
TCI IADC126 is suitable for very soft formations. It is very important to choose the right rock drill bit before starting the project.
The hardness of rocks can be classified as soft, medium, hard or very hard, and they may be different in hardness for the same rock, for example, limestone, sandstone and shale have soft limestone, medium limestone and hard limestone, medium sandstone and hard sandstone, etc.
With 15 years and more than 30 countries of service experience in drilling engineering, Far East has provided drill bits and advanced drilling souls for many customers, different applications. These include oilfield, gas, geological exploration, dredging, mining, water well drilling, HDD, construction and foundation.
If you can provide specific information, such as rock hardness, type of drilling rig, rotation speed, weight and torque of the bit, we can provide you with an engineer's exclusive solution. When you tell us about vertical drilling, horizontal drilling, oil well drilling, no-dig drilling or foundation piling, it also helps us to find the right drill bit for you.
Product Specification
5 1/4" is always used in exploration, water well drilling and cement plug drilling, it has a central flush hole for mud fluid circulation, the bearing is sealed and thread connection is produced in rules of API 3 1/2 reg pin.
The teeth are hard-faced by tungsten carbide, teeth life is very long in drilling mudstone and soft rocks.
