Product Description
4 Inch Reverse Circulation Drill Rods with Remet Thread
Reverse circulation drilling is essential for mineral exploration and resource definition programs. Our 4-inch drill rods with 4-inch Remet thread connections are engineered specifically for RC Hammer RE542 drilling applications.
RC Drilling Applications
Reverse circulation drilling encompasses two primary methods:
- RC with Hammer: Designed for medium to hard rock formations, capable of reaching depths up to 800 meters using 4-inch and 4½-inch diameter rods
- Air Core Drilling: Optimized for softer oxide and clay ground conditions, reaching depths of 100 meters with 3-inch to 3½-inch rods
Premium Quality Construction
Roschen manufactures a comprehensive range of reverse circulation drill rods from 3½-inch to 10¾-inch diameters with various thread connections. Our advanced manufacturing technologies ensure exceptional strength, superior wear resistance, and extended service life.
Dual Wall Design
These RC dual wall drill rods feature an outer drill rod with an inner tube assembly. When connected, the inner tubes create a sealed continuous pathway for efficient cuttings transport from the bit face to surface collection systems.
