CS Unitec 24" Threaded Core Barrel – 1-1/4" diameter

CS Unitec 24" Threaded Core Barrel – 1-1/4" diameter Product Guide

This product is a threaded diamond core barrel designed specifically for deep drilling applications in reinforced concrete and masonry. It addresses the need for an efficient drilling solution that allows operators to bore precise holes of consistent diameter through tough materials, often as part of structural, electrical, plumbing, or mechanical installations.

This type of core barrel is commonly used with electric, pneumatic, or hydraulic drill rigs to extend the reach of core bits for deeper cuts. It screws onto compatible core bits and rigs, effectively increasing drilling depth without sacrificing bit alignment or stability. Rental customers often select these barrels to adapt existing drill setups for jobs requiring extended core lengths, particularly when drilling through thick concrete slabs, walls, or foundations.

Where This Is Used

• Construction sites requiring deep core drilling through reinforced concrete or masonry
• Concrete repair and inspection projects needing core sampling or penetrations
• Infrastructure installations including plumbing, electrical conduits, and mechanical penetrations in slabs and walls

Key Details

Selection Notes

When selecting a core barrel extension, verify the diameter and thread type to ensure proper compatibility with your core bits and drill rig. This barrel is sized at 1-1/4" diameter, fitting correspondingly sized bits and rigs. The 24" length is suitable for deeper drilling needs but should be matched to the project's required hole depth and rig capacity. Consider the segment type and thickness on the core bit, especially when working with reinforced concrete, to optimize cutting efficiency. Also, plan for slurry or water management during drilling to minimize mess and improve bit life.

Drill Setup Notes

Ensure the core barrel is tightly threaded to the matching core bit to prevent wobble or misalignment. Confirm that your drilling rig supports the barrel’s length and diameter without overloading its mount or motor. Standard safety and operational checks prior to drilling include inspecting the threads for damage or wear and verifying all connections are secure. Because this barrel is designed for use with electric, hydraulic, or pneumatic rigs, make certain the power source matches your drill rig setup. After drilling, clean the barrel and attached core bits to remove concrete slurry and debris before storage or reuse to support tool longevity.
