CS Unitec 48" Threaded Core Barrel – 2-1/2" diameter

CS Unitec 48" Threaded Core Barrel – 2-1/2" diameter Product Guide

This product is a threaded diamond core barrel designed for deep drilling tasks in reinforced concrete and masonry materials. It addresses the challenge of efficiently creating deep, clean cores for structural testing, installations, or penetrating tough materials where precision and durability are required.

Threaded core barrels like this are commonly used with various drilling rigs, including electric, pneumatic, and hydraulic setups. Their threaded connection system allows for secure attachment to compatible core bits and drill rods, facilitating deep core drilling in demanding applications. Rental users typically deploy these barrels when requiring cores greater than standard depths or when working with particularly dense or reinforced substrates.

Where This Is Used

• Structural analysis and testing in reinforced concrete construction
• Installation and placement of anchors, bolts, or embedded equipment
• Core sampling for material evaluation in masonry and concrete floors or walls

Key Details

Selection Notes

From a selection standpoint, this threaded core barrel is chosen when deep cores exceeding typical barrel lengths are needed. The 2-1/2" diameter is a common size for applications that balance manageable core size with sufficient sample volume. It's important to verify that drill rig chuck or adapter systems match the threaded connection size and style. Consider the length of the barrel relative to drilling depth requirements, as well as the compatibility with core bits of appropriate segment thickness for the material hardness.

Ensure that the drill rig power source (electric, pneumatic, or hydraulic) is suitable for the feed force and torque demands of the combined barrel and bit assembly. Planning for slurry and water supply to the drill face is also critical to maximize bit life and maintain drilling efficiency.

Drill Setup Notes

Setup requires confirming threaded connection compatibility between the barrel, core bit, and drill rod to prevent loosening during operation. Proper mounting and rig stability will help maintain straight drilling and avoid damage to both the barrel and drill rig. Manage water or slurry flow at the cutting interface to carry debris away effectively, particularly when drilling reinforced or dense concrete.

For hydraulic or pneumatic rigs, verify hose or air-line length and routing to ensure unrestricted supply and ease of operator access. When using this barrel top-side, cleaning the equipment after use by removing slurry and inspecting threads for wear will support tool longevity.
