API tricone drilling IADC127 4 5/8 inches (118mm) for sale

Product Description

Wholesale API steel tooth tricone rock sealed drill bits in the stock based on the lowest price and excellent quality from China factory
Bit Description:
IADC: 127 - Steel tooth journal sealed bearing bit with gauge protection 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.

According to cutting material,three cones bit can be divided into TCI bit and Milled Tooth Bit
Steel tooth tricone bits have another name milled tooth tricone bit since the teeth are produced by milling machine, the cone surface is hard-faced by tungsten carbide.
Milled tooth IADC127 is for very soft formation. Choose the proper rocks drilling bits is very important before starting project.
Rocks hardness could be soft , medium and hard or very hard, hardness of one type of rocks may be also a little different, for example, limestone, sandstone, shale has soft limestone, medium limestone and hard limestone, medium sandstone and hard sandstone , etc.

In drilling project, Far Eastern have 15 years and more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including oil field,natural gas,geological exploration,driectional boring,mining ,water well drilling ,HDD, construction,and foundation.The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of drill bits. We can give our engineer's solution when you can supply specific conditions, such as hardness of rocks,types of drilling rig,rotary speed,weight on bit and torque. It is also hlep us to find the siutable drill bits after you can tell us vertical well drilling or horizontal drilling ,oil well drilling or No-Dig drilling or foundation piling.
