CS Unitec 36" Threaded Core Barrel – 9" diameter

CS Unitec 36" Threaded Core Barrel – 9" diameter Product Guide

The CS Unitec 36" Threaded Core Barrel with a 9" diameter is a specialized drilling accessory designed to extend the reach of core drilling rigs for deep drilling applications. It addresses the challenge of drilling long, precise holes through reinforced concrete and masonry where standard-length barrels or bits are insufficient to achieve required depths.

This type of product is commonly used with electric, pneumatic, or hydraulic core drill rigs in construction and industrial environments. The threaded core barrel attaches securely to the drill bit and rig, allowing operators to drill deeper than typical barrel lengths while maintaining bit stability and control. It is especially useful when working on projects requiring extended depth drilling such as foundations, utility penetrations, or infrastructure repairs where long, clean cores are needed for inspection or removal.

Where This Is Used

• Deep drilling operations in reinforced concrete for infrastructure or commercial construction projects
• Masonry drilling applications requiring extended depth cores
• Electric, pneumatic, or hydraulic drill rigs that support threaded barrels

Key Details

Selection Notes

From a selection standpoint, confirm that the core barrel length and diameter match the drilling depth and hole size required for the project. Since this product is designed for deep drilling in reinforced concrete and masonry, verify compatibility with the drill rig’s mounting and torque capabilities. Check that the threaded connection conforms to the bit and rig thread standards to ensure secure assembly. The appropriate segment thickness (0.250" for 7" to 10" diameters) helps maintain cutting effectiveness during prolonged drilling.

Drill Setup Notes

When setting up the core barrel, ensure the bit and barrel threads are clean and free of debris to allow reliable and tight connections. Plan for slurry and water supply management during drilling to maintain bit coolness and remove debris from the hole. For hydraulic or pneumatic rigs, verify the power source compatibility and connection points before use. After drilling, clean concrete slurry and debris from the barrel, bit, and connections to support tool longevity and future use.
