CS Unitec 48" Threaded Core Barrel – 1-1/2" diameter

CS Unitec 48" Threaded Core Barrel – 1-1/2" diameter Product Guide

This product is a 48-inch long threaded diamond core barrel with a 1-1/2 inch diameter, designed for deep drilling applications in reinforced concrete and masonry structures. It serves as an extension or replacement core barrel, allowing operators to drill to greater depths without sacrificing cutting efficiency or stability.

Threaded core barrels like this one are commonly used with electric, pneumatic, or hydraulic drill rigs in the field. They allow technicians to bore deep, precise holes for installations such as plumbing, electrical conduits, or structural testing. The product’s compatibility with multiple power sources increases its versatility across different job sites and equipment types.

Where This Is Used

• Deep drilling in reinforced concrete for mechanical or electrical penetrations
• Masonry core drilling for anchor installation or inspection purposes
• Extension drilling setups where greater depth is required beyond standard barrel lengths

Key Details

Selection Notes

When selecting a core barrel for deep drilling, verify compatibility with the core drill rig, focusing on thread size and type as well as barrel diameter. The 1-1/2 inch diameter is suitable for smaller-diameter hole requirements, often used for pilot holes, sampling, or smaller sleeve penetrations. The 48-inch length provides extended drilling depth capabilities, but jobsite clearance and transport considerations must be taken into account. Consider matching segment hardness and design with the material being drilled to optimize cut quality and barrel longevity. Ensure that the drill rig’s power source supports the barrel length and bit size, preventing overstress or reduced rotational speed.

Drill Setup Notes

Proper threading torque and clean thread surfaces are essential when assembling the core barrel to the drill rig and bit to avoid loosening during operation. Because this barrel is designed for use with diamond bits, plan for water or slurry supply to control dust and cool the bit during drilling when applicable. For pneumatic or hydraulic drills, confirm power delivery and hose or air-line routing to maintain consistent rotational speed and torque. After drilling tasks, clean slurry and concrete residue from the barrel threads and inspect for wear or damage before reassembly to promote safety and maintain drilling accuracy.
