CS Unitec 36" Threaded Core Barrel – 6" diameter

CS Unitec 36" Threaded Core Barrel – 6" diameter Product Guide

The CS Unitec 36" Threaded Core Barrel with a 6" diameter is a heavy-duty drilling accessory designed for deep core drilling applications in reinforced concrete and masonry. This product addresses the challenge of extracting precise core samples or creating clean circular openings in hard materials, often required for installation, inspection, or structural analysis.

Threaded core barrels like this one are commonly used in conjunction with electric, pneumatic, or hydraulic core drill rigs. They serve as extensions that allow drilling to extend deeper than the length of a single core bit. By adding several threaded barrels, operators can reach desired depths in thick concrete or masonry structures, maintaining alignment and enabling efficient slurry removal. The 6" diameter fits within the typical range of core bit sizes for utility installations, plumbing, electrical conduit placement, and structural testing.

Where This Is Used

• Deep core drilling in reinforced concrete slabs and walls
• Masonry penetration for plumbing, electrical, and HVAC installations
• Construction and renovation projects requiring precise circular openings and sampling

Key Details

Selection Notes

When selecting a threaded core barrel, the important details to confirm include matching the diameter and thread type with the core bit and rig being used. The 6" diameter barrel fits equal diameter bits, so confirm the bit selection aligns with this size. Length selection depends on drilling depth requirements; this 36" barrel extends drilling capacity significantly, but assess site access and drill rig capacity.

Threaded barrels are often added incrementally to reach the final depth, so ensuring thread integrity and clean connections is critical for alignment and efficient drilling. From a practical standpoint, review the rig’s power source compatibility—electric, pneumatic, or hydraulic—since this barrel supports all three via the appropriate core bit and rig interface.

Bit Selection Notes

This core barrel is designed to be used with diamond core bits featuring a .187" segment height for bit diameters up to 6-1/2". The segments are optimized for cutting reinforced concrete and masonry. When drilling at significant depths, plan for adequate water supply for cooling and slurry control, and ensure the rig’s feed mechanism can manage the extended length and weight. Proper bit selection based on material hardness and aggregate type will also influence drilling speed and core integrity.
