8.5″ inches fixed cutter PDC Bi center bit suppliers for rock drilling

Product Description

Wholesale API PDC Bi Center Drill bit in the stock from China OEM manufacturer.
Our Bi-Center drilling bits pay attention to hydraulics optimization to improve both cuttings removal. We also ensure effective cutter cooling. In order to the improved hydraulics configuration, we also care the cutting structure to ensure it is both effective and balanced.This new design is not only on a conventional assembly but also used in conjunction with bent-housing motors.
BI center bit is used for reaming hole bottom, the model No. likes 5 7/8"*7 1/2"*4 3/4" or just 5 7/8"*7 1/2" as the third diameter is not important.
5 7/8" is the passing through diameter, 7 1/2" is the reaming diameter, 4 3/4" is the diameter of front bit.
We can produce both matrix body and steel body BI center bit, the cutters could be diameter 8mm, 13mm, 16mm, 19mm, blades quantity ranges from 3 to 8.
Order procedure :
1>Confirm 3D design.
2>Trial order.
3>Testing and improvment.
4>Mass production.
If the requirement is not regular, we have mature design according to various of drilling conditions.
