Atlas / Furukawa / / Tamrock T51 Half-bridge Threaded Coupling Sleeve Drill pipe speed extension drill

Elongated connecting rod coupled to the sleeve. High-quality steel and CNC machining to ensure that our reliable and consistent quality control coupling sleeve. When using a rock drilling machine with a conventional male adapter and the shank rod drift, the need for a coupling rod connecting the adapter to float, to ensure contact with both ends, in order to achieve efficient energy transfer.
The coupling sleeve is also used in the same manner as few connecting rod to each other. Intermediate coupling sleeve has a stop to prevent excessive screwed to the drill rod.

The main producing mines, compression, tunneling, quarrying and other related industries rig. Design and manufacture according to customer requirements.
