Sealed Bearing Rock Roller Bits With Cemented Carbide Insert For Soft Formation
Click here for catalogueTCI DRILL BIT.pdf
IADC 4 SERIES DRILL BITS
These bits are used to drill low compressive strength, very soft formations.
The bits maximize the use of both conical and chisel inserts of large diameters and high projection.
This cutting structure design, combined with maximum cone offset, results in high bit penetration rates.
The deep intermesh of cutter rows prevents bit balling in sticky formations.

Application
Tricone drill bit is the best all-purpose drill bit and can be used for many different types of rock formations, such as Soft Rock Formations (consist mainly of sand, clay, limestone or shale), Medium Rock Formations (calcites, dolomites, hard limestones, and some hard shale), Hard and Abrasive Formation (hard shale, calcites, mudstones, chert, pyrite, granite, quartzite, and cherty lime stones).
Advantage:
1. Strictly select the material to ensure the reliable quality. Bad steel and tungsten carbide inserts won't be used.
2. Strictly act according to the ISO9001 standard, and control by full-scale inspection.
3. Sales and support people are highly trained in the latest rock drilling technology and can offer you expert advice on what products will best fit a specific end use application.
