Product Description

GAT series bit adopts rubber seal with roller Bearing which is the ideal and economical tool for drilling applications where middle to low WOB and high RPM are required.

Main structure features:
1.Sealed roller bearing structure. With roller arranged in grooves recessed in the cone body, the size of the bearing journal is increased, therefore, with the ability of enduring high WOB and applying for high RPM.
2.Thrust bearing surfaces are hardface and treated with friction reducing technology.
All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.


GAT Steel tooth tricone bit

IADC CODE-TRICOEN BITS
First Digit-1,2,3 designate steel tooth bits and the formation being drilled,with 1 for soft,2 for medium,and 3 for hard formations.4,5,6,7,and 8 designate tungsten carbide insert bits and the formation being drilled,with 4 being the softest and 8 the hardest formation.
Second Digit-1,2,3 and 4 are further broken down by the formation,with 1 being the softest and 4 the hardest.
Third Digit-Classifies the bit according to bearing/seal type and special gauge/wear protection.

1.Open Bearing-On these bits the cones will spin freely.The bit has a front row of ball bearings and a back row of roller bearings.
2.Opening Bearing,Air-Cooled-Cones are similar to#1.but have air injection directly to the cones to cool the bearings.Air flows into the cone through the passage ways inside the pin.(Not for use in mud applications.)
3.Open Bearing with Gauge Protection-Carbide inserts in the heel of the cone.
4. Sealed Roller Bearing-These bits have an o-ring seal with a grease reservoir for bearing cooling.The seal acts as a barrier against mud and cuttings to protect the bearings.
5.Sealed Roller Bearing with Gauge Protect-Carbide inserts in the heel of the cone.
6.Sealed Journal Roller Bearing-These bits are strictlt oil/grease cooled with nose bearings,o-ring seal and a race for maximum performance.
7.Sealed Journal Rolling Bearing with gauge protect-Carbide inserts in the heel of the cone.
Fourth Digit-used to indicate additional features.

A. Air Application E: Extended Jet X: Chisel Insert C: Center Jet G: Extra Gauge Protection Y: Conical Insert
S:Standard Steel Tooth J: Jet Deflection Z:Other Insert Shape D:Deviation Control R:Reinforced Welds
