Rotary Subs

Useful in BHA’s as a cross over or saver sub for certain components.



Rotary subs are most commonly known as cross over subs, bit subs, float subs, and saver subs. They are useful when drill string components have differing
connections. There are a variety of types and sizes depending on the application. All of our rotary subs are manufactured to DS-1 specifications and
cut by API licensed machine shops.
