Tricone bit Cutting Structure.
1. The durability of premium tungsten carbide inserts is improved
with new formulas and new techniques for insert bit.
2. Tricone bit Gauge Structure
Multiple gauge protection with gauge trimmers on heel and gauge
inserts on the gauge surface of the cone, tungsten carbide inserts
and hardfacing on the shirttail increases gauge holding capability
and bearing life.
3. Tricone bit Sealed Bearing Structure and Lubrication
High precision bearing with two thrust faces. Balls lock the
cone.Hardface heard bearing surface. Cone bearing inlaid with
friction-reducing alloy. Abrasion resistance and seizure resistance
of the bearing are improved and suitable for high rotary speed.
Grease compensator to maintain pressure inside the bearing and
improve lubrication.
4. Tricone bit Sealed Bearing Structure
API standard threads are turned with precision machining making
them concentric to the gage rows for uniform loading on bearings.
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).
