TW QV Series Thin-wall Rods
The TW QV Series Thin-Wall Rods are precision-engineered for diamond core drilling applications requiring high strength, reduced weight, and efficient core recovery. Manufactured from high-grade alloy steel, these rods feature a thin-wall design that minimizes annular space, enhances flushing efficiency, and reduces drilling resistance—making them ideal for deep hole drilling and challenging ground conditions.
Designed for compatibility with standard Q-series tooling, the TW QV rods ensure a tight, secure connection and long service life even under demanding operational conditions.
