CS Unitec 12" Threaded Core Barrel – 1" diameter

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

This product is a threaded diamond core barrel with a 12-inch length and a 1-inch diameter. It is designed to be attached to compatible drill rigs for deep drilling applications, particularly in reinforced concrete and masonry. The core barrel allows for the efficient removal of cylindrical cores from hard materials by attaching diamond-tipped segments that cut through the substrate.

Threaded core barrels like this one are commonly used on electric, pneumatic, or hydraulic core drills in the field. They are selected to match the specific drilling equipment and bit diameter, enabling precise and controlled core extraction in demanding construction, repair, or inspection tasks. Rental and project support often focus on ensuring proper compatibility with the drill rig’s chuck and thread size as well as verifying the required bit diameter for the material and application.

Where This Is Used

• Drilling cores in reinforced concrete structures for testing, removal, or installation of utilities.
• Masonry drilling where precision holes are needed for fixtures or analysis.
• Prepping concrete surfaces for infrastructure repair, including bridges, buildings, or roadways.

Key Details

Selection Notes

When selecting a threaded core barrel for a drilling job, the crucial factors include the diameter of the core required and the compatibility with the drill rig’s mounting system. For a 1" diameter core barrel, confirm that the drill rig can accept that size and thread type. The 12" barrel length is suitable for medium-depth drilling but verify clearance and reach required for the specific project. Segment size and type must match the material; this standard 1" diameter core barrel uses a .187" diamond segment suitable for reinforced concrete and masonry. Consider the drilling method—electric, pneumatic, or hydraulic—to ensure the core barrel's compatibility and performance with the power source. Planning also involves confirming that slurries or dust from drilling can be managed appropriately on site.

Drill Setup Notes

Proper setup involves securely threading the core barrel onto the drill rig and ensuring all connections are firm to prevent loosening during the drilling process. Confirm that the drill rig’s speed and feed align with the core barrel’s diameter and segment specifications. When using in hydraulic or pneumatic rigs, verify hose or air-line routing to avoid bends or restrictions that could reduce flow or pressure at the drill point. Since this is a topside core barrel without specific underwater capability mentioned, standard slurry and water management practices should be followed. After completion of drilling, clean the bit and barrel assembly of any concrete slurry or debris, inspect threads and segments for wear, and prepare the tool for the next use to maintain reliability.
