CS Unitec 24" Threaded Core Barrel – 2-1/4" diameter

CS Unitec 24" Threaded Core Barrel – 2-1/4" diameter Product Guide

The CS Unitec 24" Threaded Core Barrel is a specialized accessory designed for deep drilling applications in reinforced concrete and masonry. This product addresses the challenge of creating precise, deep core holes where standard drilling bits may be inadequate, especially when longer drilling lengths are necessary.

Commonly used with electric, pneumatic, and hydraulic core drills, this threaded core barrel extends drilling reach by allowing multiple barrels and bits to be connected in sequence. This modularity facilitates the drilling of deep holes without the need to reposition or switch tools frequently, providing more continuous work and reducing downtime on the job.

Where This Is Used

• Deep core drilling through reinforced concrete and masonry structures
• Infrastructure projects requiring precise diameter holes for utilities or reinforcements
• Commercial and industrial construction sites needing extended drilling depth beyond standard bit lengths

Key Details

Selection Notes

When selecting a threaded core barrel of this length and diameter, confirm the drill rig's ability to handle the added length and torque stresses during operation. The 2-1/4" diameter suits applications where relatively narrow core holes are required but with substantial depth. Matching the flange thread size and type to your equipment is critical to ensure safe and effective barrel and bit assembly. Consider the material and reinforcement density since harder, more abrasive concrete may demand more frequent barrel inspection and maintenance during extended drilling sequences.

Drill Setup Notes

Threaded core barrels are typically combined in sequence to reach the necessary drilling depth. When using this product, verify each connection is securely tightened to prevent loosening under drilling torque. Monitor the cooling and flushing method—water or slurry supply should be planned to control heat and remove debris effectively during the deep drilling operation. Keep the drill rig stable and aligned to reduce stress on the jointed barrels to minimize the risk of barrel or bit damage. Regularly inspect threads for wear and clean connections before and after use to prolong tool life and maintain efficient drilling performance.
