Description:
Drill subs are an important integral part of everyday drilling. Not having the right thread adapter can make your life miserable. We have a large inventory of common and not so common sizes. Custom sizes are always available.
Rotary subs have two primary applications. They can be used to cross over from one connection size to another, or as the disposable component used to extend the connection life of a more expensive drill stem member.
Installing a float sub (with check valve) is always a good idea when drilling in wet situations
