Atlas / Furukawa / / Tamrock GT60 Half-bridge Threaded Coupling Sleeve Drill pipe speed extension drill

Elongated rod connected to the sleeve. Quality steel and CNC machining ensures our reliable and consistent quality control coupling sleeve. When using the drilling machine when a conventional male adapter and club drift, need to be connected with the coupling bar adapter floated, to ensure contact with both ends, in order to achieve efficient energy transfer.
Coupling sleeve use little same manner interconnected link. Intermediate connection sleeve having a stop means to prevent excessive screwed onto the drill rod.
The main producing mines, compression, tunneling, quarrying and other related industries rig. Designed and manufactured according to customer requirements.
