Drill rod using R25 R28 R32 R38 T38 thread system.

 

With wrench flats to aid in coupling/decoupling of rods for extension drilling.

 

Used in benching and long hole drilling.

 

Drilling precision can be further improved by using this as the first rod in a normal drill string. Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good rock conditions compared to rod and coupling sleeve combination system
