DCDMA J-Series Drill Rod with AWJ BWJ NWJ Drill Rods heat treated tool Joints for convention coring
Available from ROSCHEN with inertia welded, heat treated tool joints and heavy-wall construction which makes the AWJ version ideal for SPT work and the NWJ durable enough for rigorous rotary & deeper conventional coring applications.
Both thread sizes make-and-break in one & three-quarter turns & will never cross-thread.
Simply match your desired thread with your required length when ordering.
