Rotary drill adapters

Choose from a full range of rotary subs and adapters for a variety of drilling needs. Subs provide various functions such as changing from one thread form to another (cross-over subs) or reducing wear to component threads (thread-saver subs).

Features

Productive performance

Quality collaring, deck bushing and rod support help to avoid most operational failures on drill string parts. Drill string tools’ componentry is matched to a specific drill rig and bit hole size, offering stability for column strength and optimum bit/drill string performance. The drill string diameter to drill bit diameter link is particularly important when optimizing up-hole bailing velocity.
Premium quality

High-quality components are engineered to efficiently handle hard rock and abrasive formations commonly found in surface mines, quarries and construction applications. Extreme torsional and axial loads are transmitted through the rotary drill string and each component is optimized for application.
High-caliber manufacturing

Using special alloy material, all subs and adapters are manufactured to the same high-quality standards as Sandvik Drill Pipe. Rotary subs are available as bit (bottom) subs, top (spindle) subs, cross-over subs and thread-saver subs.
