A coupling sleeve is a vital component of the top hammer drill string. It is available in three types of coupling components: Full Bridge, Semi-Bridge, Cross over adapter, and Crossover coupling.

Full-Bridge Coupling Sleeves

• Eliminates the risk of the coupling creeping along the threaded joints
• Ideally suited for surface applications
• Offers enhanced uncoupling characteristics while maintaining tighter joints
• Reduces the likelihood of jamming
• Perfect for machines equipped with independent rotation
