Adaptors / Subs

A crossover sub / adaptor is used to crossover from one connection size to another or as the disposable component used to extend the connection life of a more expensive drill stem member.

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.
