Description
The TW QV Series Wireline Rods are precision-engineered thin-wall drill rods designed for high-efficiency core drilling operations. Developed for use in wireline coring systems, these rods offer a strong yet lightweight solution ideal for deep drilling in mineral exploration, geotechnical, and environmental applications.
Constructed from high-grade alloy steel, the TW QV Series rods provide excellent strength-to-weight ratio, ensuring durability under high torque and axial loads while reducing overall rig weight and fuel consumption. Their thin-wall design allows for greater core recovery and improved drilling efficiency by maximizing the inside diameter without increasing the outside diameter, making them suitable for applications where sample quality and hole stability are critical.
Precision threading ensures a tight, reliable connection with minimal risk of joint failure, while the rods’ compatibility with industry-standard tools and accessories enhances operational flexibility. Manufactured under strict quality control standards, TW QV rods are built for long service life and consistent performance in challenging drilling environments.
