Description

High Strength Drill Rod Wear Resistance Long Life 4" Reverse Circulation

ROSCHEN offers a complete line of premium quality reverse circulation, drill rods, in sizes from
3 1/2" to 10 3/4", and with a number of thread connections. All Reverse Circulation rods are
manufactured using the most advanced technologies and specifically engineered to provide high
strength, excellent wear resistance, and long life.

RC, dual wall drill rods are manufactured with an outer drill rod and an inner tube located inside the rod.
When the drill rods are threaded together, the inner tubes seal together to provide a continuous route for cuttings to travel from the bit face to the surface for collection.

Features:
1. Plain end mid-body
2. 4140 QT tool joints
3. 3.65" sq. inch weld area
4. Inertia welded - increased strength due to full face surface welds.
5. Heat treated - weld zone to further optimize the mechanical and physical properties of the rod.
Please contact your ROSCHEN representative for additional details, and ordering assistance.
