Product Overview
The ALVRIQ Core Barrel with Round Shank Chisel is designed for rotary foundation drilling applications requiring annular rock cutting with replaceable round-shank chisel teeth. The suitable configuration depends on rock conditions, rig performance and borehole dimensions.
The barrel body and wear protection can be specified for the project. Replaceable round-shank chisel teeth cut the rock around the barrel perimeter; material grade and cutting arrangement should be confirmed with the order.
The barrel configuration supports removal of drilled rock material during borehole excavation. The universal kelly box connection (interchangeable with SANY, Zoomlion, XCMG, and BAUER rotary drilling rigs) ensures broad compatibility without modification.
