API petroleum tricone drilling bit for sale in stock
Product Description
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 the teeth.
Tricone bit main feature
1)Drill bit connection made according to API and ISO standard.
2)We can adjust the bit size according to your rig.
3)The best result can be obtained by using the steel tooth bit in the soft stratum.TCI tricone bit is for hard formation.
4)Proven cutting structures and bearing desings continue to deliver a superior level of performance and reliability.
5)Optimized hydraulics provide increased ROP by efficiently removing cuttings and ensuring engagementof new rock on every cutting structuer rotation.
