CS Unitec 48" Threaded Core Barrel – 5" diameter Product Guide

The CS Unitec 48" Threaded Core Barrel is a specialized drilling accessory designed to extend the reach of core drilling operations in reinforced concrete and masonry. It solves the problem of accessing greater depths during drilling by attaching to compatible core bits and drill rigs, providing a secure and precise extension to the standard bit length.

This type of product is commonly used in the field with electric, pneumatic, or hydraulic core drilling rigs that require deep penetration without compromising the stability or alignment of the drill. It enables operators to complete deep drilling tasks that exceed the length capacity of standard core bits, maintaining drilling efficiency and bit performance in demanding industrial or construction environments.

Where This Is Used

• Deep drilling in reinforced concrete structures such as foundations, walls, and slabs
• Masonry drilling for utility installations or structural modifications requiring extended reach
• Industrial and commercial construction where precision and depth are necessary for anchor bolt or plumbing sleeve placement

Key Details

Selection Notes

From a selection standpoint, it is important to verify that the threaded core barrel matches both the bit diameter and thread type of your core drill setup. The 5" diameter is common for moderate-sized core drilling jobs requiring deeper penetration. Consider the total drilling depth needed and ensure the combined length of core barrel and bit can handle the project requirements. Confirm that your drill rig—whether electric, pneumatic, or hydraulic—supports the barrel length and weight for stable operation. The segment design of the barrel’s cutting edge should match the material being drilled to optimize cutting life and slurry removal.

Setup Notes

Proper setup involves securely attaching the core barrel to the drill bit and rig with clean, undamaged threads to prevent slippage or binding during drilling. Clearance for the 48" barrel length must be ensured on the worksite, accounting for operator space and rig positioning. When used with hydraulic or pneumatic rigs, verify hose or air-line routing to avoid kinks or interference with the barrel. Water supply planning is crucial for dust reduction and cooling; maintain slurry flow to prevent clogging. After use, clean concrete slurry, dust, and debris thoroughly from the core barrel and inspect threaded connections before the next drilling operation. This supports reliability and extends tool life.
