CS Unitec 12" Threaded Core Barrel – 1-1/4" diameter

CS Unitec 12" Threaded Core Barrel – 1-1/4" diameter Product Guide

The CS Unitec 12" Threaded Core Barrel is a heavy-duty diamond core drilling accessory designed for deep drilling applications in reinforced concrete and masonry. It solves the problem of efficiently removing cylindrical cores from tough materials, allowing for clean, precise holes needed in construction, utility installation, and infrastructure repair tasks.

This type of product is commonly used as part of drill rig setups that may be electric, pneumatic, or hydraulic, depending on the drilling equipment. The threaded core barrel attaches securely to compatible drill bits and rigs to extend drilling depth while maintaining bit stability and effective removal of cut material. Its durable diamond segments handle abrasive materials typically found in industrial and construction environments.

Where This Is Used

• Reinforced concrete drilling for plumbing, electrical, or mechanical penetrations
• Masonry core drilling for structural testing or openings
• Industrial construction and infrastructure projects requiring precision deep cores

Key Details

Selection Notes

From a selection standpoint, confirm the core barrel diameter matches the required hole size for the job, and ensure the length suits the drilling depth without compromising stability or causing excessive drill strain. Threaded connection compatibility with the drill rig and core bit is critical for reliable performance. Consider the material hardness and reinforcement in the substrate to match segment type and size for effective drilling and cutting life.

Drill Setup Notes

Plan for a stable mounting or rig setup capable of supporting the core barrel and bit assembly under drilling torsion and thrust loads. Confirm the drill rig power source (electric, pneumatic, or hydraulic) matches the barrel’s compatibility. When using hydraulic or pneumatic rigs, hose or air-line routing to the drill must be free of kinks or restrictions to maintain flow and pressure. For hydraulic systems, verify fluid compatibility and connections. Ensure proper water or slurry supply to the drill point to cool the bit and flush out debris for consistent cutting and to extend tooling life.
