API tricone drill bits manufacturer IADC637 12 1/4 ” (311.1mm)

Product Description

Tricone drill bit 6 1/2 inch sealed bearing oil well hard rock bit mining API tricone drill bit Apply to oil well ,gas well, Construction, Water Drilling, Mining, Horizontal Directional Drilling, Geothermal and Environ-mental. The roller cone bit is the most widely used tool in petroleum drilling and geological drilling. Tricone bit has the function of impacting, crushing and shearing rock in formation, so it can adapt to soft, medium and hard formation. The cone bit can be divided into milling (steel teeth) cone bit and TCI cone bit according to the type of teeth.
We have our own experienced QC.There will be strict inspection and testing for every order before shipping out.
We pass the qualifications API and ISO certificate for tricone bit and PDC drilling bits.

Feature： 1. Drill Bit Connection made according to API standard. 2. We can adjust the bit size according to your rig. 3.Proven cutting structures and bearing designs continue to deliver a high quality of performance and reliability. 4.Optimized hydraulics provide increased ROP by efficiently removing cuttings and ensuring engagement of new rock on every cutting structure rotation.
