new saver sub and crossover sub for well  drilling bit

Product Description

Bit Subs

A bit sub is a short, threaded piece of pipe used to adapt parts of the drilling string that cannot otherwise be screwed together because of differences in thread size or design.


Crossover Sub

Drill Crossover Subs are used as an adapter between two different types or sizes of threads.  

A bit sub is a sub that is used just above the bit and serves as a crossover between the drill collar connections and the bit connection


Detailed Introduction of Saver Sub

saver sub is used to extend the life of the bit by taking the  connection wear each time it is make 

to a drill stem component. The saver sub connection is sacrificed because it can be easily repaired or  

inexpensively replaced. The saver sub can be equipped with a rubber protector to reduce BOP  

equipment and casing wear resulting from contact damage with a lower bit connection.
