The OD of this roller cone is 150mm, it is for building 9 7/8″ tri-one bits, it is one-thirds(1/3) of 9 7/8″ tricone bit.
We guarantee it is almost the best quality roller cone bit in the world at the same size.
The price is higher than Elastomer sealed bearing roller cone bit, but the cost-performance(cost of drilling per meter) is much higher than Elastomer bearing ones in drilling very deep well or very long and hard HDD projects, the working life is extremely long which supports to finish drilling at one time.
