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.
| Straight subs | Used to connect drill stem members that have a similar OD. |
| Reduced-section sub | Used to connect drill stem members that have different diameters that warrant the cross-sectional change necessary to accommodate different connections |
| Saver sub | Used to extend the life of the rotary kelly by taking the connection wear each time it is made up to a drill stem component |
| Bit sub | Size availability ranges from 3 1/8" to 11" OD and 36" to 48" length |
| Lift sub | A lift sub enables the safe, efficient handling of straight OD tubular-such as drill collars, shock tools, jars, directional equipment, and other tools-by using the drill pipe elevators |
| Top drive sub | Top drive subs serve as the sacrificial element between the drill string and the top drive, reducing repair and maintenance costs |
