Product Description

API sealed bearing IADC617 tricone bit supplier for hard rock drilling.
IADC: 617 is TCI journal sealed bearing bit with gauge protection for medium hard formations with high compressive strength.
The 617 features robust chisel tungsten carbide inserts on the heel row and conical onthe inner rows.This design provide a fast drilling rate and added cutting structure durability in medium to medium hard formations.The HSN rubber O-ring provides adequate sealing for bearing durability.
The TCI tricone bit mainly used for oil welldrilling for soft to medum hard rocks.
We are API and ISO factory of drilling bits. All bits are 100% brand new.
Welcome to visit our factory. We can show our company's video for your reference!
Anything you need, please tell us. We hope that can cooperate with you in drilling project.
