SUBS, SUBS, SUBS,.........those
essential parts needed by every driller to connect from one size rod, casing, or bit to
another size. We at Environmental Drilling Supply & Services, Inc. understand the
urgency involved when an entire job is stopped for lack of one sub. This is the very
reason we stock about 4,000 various sized subs for all types of jobs and drilling
requirements.
We carry subs that are all manufactured with 4140 Alloy Steel and meet all
DCDMA specifications. Most subs are heat treated for longer wear. Our most commonly
requested subs may be found here on this site, however, there are many other sizes which
we stock that are not listed. If you need additional subs or information just call. We
probably have it in stock!!!
