Product Description

Production Name :

 Tricone bit is a rock drilling Tool with tungsten carbide insert  used on the rock  oil mining water or oil well . This rock drilling tool is manufactured according to API spec which are the API certification products. . Tungsten carbide material is very  hard material which hardness is only lower diamond in all the material . Comparetly ,the Diamond drill bit , Tungsten carbide  drill bit price is lower .   Tricone drill bit is called roller cone bit accroding to API standard .
 Tricone bit  is used tungsten carbide materail Tooth to  cut the rock which are split two type roller cone bit  welding TC Milled Tooth  and TCI Inserted .

TC Milled tooth and TCI inserted drill bit are customized Drill Bit accordin to the Rock grad. TCI Tricone bit is used for the middle hard to hard rock formation .
Milled tooth (all called steel tooth )tricone drill bit is used for soft to very soft rock fromation . 

This drilling tool is wided used in the mining well (such as coal mines, copper mines, and other rare metal mines),water well , oil /gas well and  geological prospecting .


Application:


TCI (Tungsten Carbide Insert) and Steel Tooth Tricone Bits. Each type is uniquely designed to tackle specific drilling challenges and geological formations with precision and efficiency.


TCI Tricone Bits featuring :

Tungsten carbide inserts, excel in drilling operations in middle to hard rock formations. These bits offer a variety of carbide inserts, including spherically shaped inserts for very hard rock and conically shaped inserts for softer rock, catering to the diverse hardness levels encountered during drilling endeavors.

The number of insert rows directly correlates with the application type and hole size, ensuring customizable configurations for optimal drilling performance. Operators can choose between open and sealed bearings, along with three shirttail protection options, enhancing durability and performance in challenging drilling conditions.

Steel Tooth Tricone Bits :

Steel Tooth Tricone Bit are renowned for their effectiveness in drilling applications across a spectrum of geological formations.
 
These bits are particularly well-suited for drilling in shale formations, soft limestone sites, fast drilling in various strata, natural gas drilling, deep wells, and abrasive formations.


The unique design and materials used in Steel Tooth Tricone Bits make them ideal for navigating through these challenging formations with efficiency and precision, ensuring consistent drilling performance in diverse drilling environments .
