Product Overview
The ALVRIQ Core Barrel with Crossing Cutters uses a crossing cutter arrangement for rock excavation in rotary foundation drilling. Configuration depends on formation, borehole diameter and rig capability.
The cutting edge and barrel body should be specified for the required ground conditions, wear demands and connection.
A universal kelly box connection (interchangeable with SANY, Zoomlion, XCMG, and BAUER rotary drilling rigs) ensures broad compatibility. Cutter layout and maintenance details are confirmed for each project.

Frequently Asked Questions
What is a core barrel with crossing cutters used for?
Crossing cutters help break and excavate suitable rock during rotary piling and foundation drilling. The final cutting arrangement depends on rock characteristics.
Is this the same as a double-wall sampling core barrel?
No. Crossing cutters describe a cutting arrangement, while double-wall sampling barrels are designed for collecting core samples.
What details are needed to request a quote?
Please share borehole diameter, rig model, kelly box dimensions, rock conditions and quantity.
