Product Description

IADC417 tricone bit is TCI sealed bearing bit with gauge protection. It is for soft formations ,such as salts and limestones,clays,sandstones,dolomites
The tricone bits have type of Tungsten Carbide Insert (TCI ) and Mill Tooth (Steel Tooth) according to cutting materials.
They are versatile and can cut through many formations type.The mill tooth tricone drill bit is used for soft formations. The TCI rotary tricone bits is used for medium and hard formations. Soft rock formations include unconsolidated sands,clays,soft limestones,redbeds and shale. Medium hard formations include dolomites,limestones,and hard shale,while hard formations include hard shale,while hard formations include hard shale,mudstones,cherty limestones and hard and abrasive formations.

Our tricone bit is application for petorleum & gas,water well,mining,construction,geothermal,directional boring and underground foundation work.
Our tricone drill bit include single rock bit,tricone bit and assemble rock bit.For the different materials,we have mill tooth /steel tooth tricne bit and TCI insert tricone bit.
Rock bit is the most widely used.Cone bit work cutting teeth alternating contact the bottom of the well, the rock breaking torque is small,contacting area is small,high specific pressure easy to eat into the stratum;the total length of working dege is big, so relatively reduce wear.Cone bit can adapt to a variety of fomration from soft to hard.
