CS Unitec 12" Threaded Core Barrel – 2" diameter Product Guide

This product is a threaded diamond core barrel designed for deep drilling tasks, specifically in reinforced concrete and masonry materials. The core barrel enhances the drilling process by providing a durable and precise housing for diamond core bits, facilitating the extraction of cylindrical concrete samples or creating clean holes for pipes, conduits, or anchor installations.

Threaded core barrels like this one are commonly used in the field with hydraulic, pneumatic, or electric core drill rigs. The barrel is attached to the drill rig and matched with the appropriate diamond core bit, allowing operators to perform efficient deep core drilling. The threaded connection ensures secure assembly of different bit lengths and diameters as needed for specific drilling depths and hole sizes.

Where This Is Used

• Reinforced concrete and masonry drilling on construction sites
• Core sampling for material testing and structural analysis
• Installation of mechanical, electrical, and plumbing systems requiring precise boreholes

Key Details

Selection Notes

When selecting this core barrel, confirm the bit diameter matches your drilling requirements and that the core drill rig used supports 2" diameter bits. Length selection depends on the depth of penetration needed. Because these barrels have threaded connections, compatibility with the core bit and drill rig spindle threads is critical. For reinforced concrete, choosing a diamond segment thickness appropriate to the hole diameter will influence drilling speed and bit life. Consider the drilling method power source—hydraulic, pneumatic, or electric—to ensure the core barrel and bits are mounted accordingly.

Drill Setup Notes

Secure the core barrel by threading it firmly onto the diamond core bit, then attach the assembly to the compatible core drill rig spindle. Ensure the equipment matches the diameter and length of the barrel and that the drill rig can apply steady pressure to maintain drilling efficiency through dense concrete substrates. Water or drilling slurry management should be planned for, keeping the drill area clear of debris and controlling slurry flow to maintain bit cooling and visibility. Inspect thread integrity and cleanliness before and after use to prevent cross-threading and ensure reliable connections.
