CS Unitec 24" Threaded Core Barrel – 2-1/2" diameter

CS Unitec 24" Threaded Core Barrel – 2-1/2" diameter Product Guide

The CS Unitec 24" Threaded Core Barrel is a diamond core barrel designed for deep drilling tasks targeting reinforced concrete and masonry. Its threaded design allows secure mounting to compatible core bits and drill rigs, providing an efficient solution for extracting precise core samples or creating clean openings in tough materials.

This type of core barrel is commonly used with electric, pneumatic, or hydraulic drill rigs, enabling heavy-duty drilling in construction, structural testing, and industrial applications. The threaded connection ensures compatibility with various bits and rig systems, supporting safe, stable drilling over extended depths. In rental operations, the issue is often selecting the correct barrel length and diameter to match both the bit and the rig's power and mounting system.

Where This Is Used

• Concrete coring for structural analysis or demolition preparation
• Masonry drilling in commercial and industrial construction sites
• Installation of anchor bolts or utility penetrations

Key Details

Selection Notes

From a selection standpoint, the important details to confirm are the compatibility of the barrel diameter and thread with your drill rig and core bit. The 2-1/2" diameter barrel is intended for moderate core hole sizes commonly used for utility penetrations and sample collection. Consider the drilling depth required and select barrel length accordingly—this product features a 24" barrel length suitable for deeper core drilling beyond surface slabs. Matching the diamond segment thickness on the bit is critical to maintain cutting efficiency based on the material hardness and core diameter. Always review rig capacity for barrel length and bit size to ensure stable and balanced operation.

Drill Setup Notes

Prepare for drilling by securely mounting the threaded core barrel onto the compatible core bit, ensuring the threads are clean and undamaged to avoid loosening during operation. Confirm the drill rig’s torque and feed settings align with the barrel size and material to be drilled to prevent premature tool or bit wear. Adequate water supply or slurry management should be planned to cool the bit and clear cuttings. Check hose or air-line routing and accommodate necessary access to the drill point for operator handling and clear debris removal. Inspect the barrel before each use for signs of wear or damage, especially the threading and diamond segments, to maintain drilling performance and safety.
