Description

Product Description

Roller cone bits is the most important drilling tools in oil and gas, water, geothermal industry. Drill bit is the lowest of all teh drilling tools and quipment, which is connected with near-bit stabilizer.

Tricone bits are used in general to drill a wide variety of rocks, Medium hard with compressive strength and thick and hard stringers ,such as limestone, hard shale, mudstone and sandstone, etc.

Type: Tungsten Carbide Insert (TCI) Bits and Milled-tooth Bits

IADC Code is very important code for us to quote you as it is a three-digit application-related code, which will indicate the working environment, working condition.
