CS Unitec 36" Threaded Core Barrel – 1-1/2" diameter

CS Unitec 36" Threaded Core Barrel – 1-1/2" diameter Product Guide

The CS Unitec 36" Threaded Core Barrel with a 1-1/2" diameter is a dedicated drilling accessory designed for deep core drilling applications. It solves the problem of extracting precise cylindrical samples or creating openings in reinforced concrete, masonry, and similar hard materials by providing a durable, threaded barrel that connects to core drills.

This type of product is commonly used in the field by contractors and rental users who operate hydraulic, pneumatic, or electric core drilling rigs. The threaded core barrel is attached to the drill and a diamond core bit, enabling drilling into tough substrates to create clean, controlled holes. Its 36" length allows deeper drilling operations, reducing the need to frequently switch barrels or bits when working on thick structures.

Where This Is Used

• Drilling precise cores in reinforced concrete walls, floors, and foundations for penetrations or sampling
• Creating openings for plumbing, electrical conduit, or HVAC installations in masonry or concrete
• Geotechnical or structural sampling in construction and renovation projects requiring subsurface analysis

Key Details

Selection Notes

From a selection standpoint, confirm the core barrel length suits the depth of the drilling application to avoid excessive setup changes. The 1-1/2" diameter is suited for smaller holes often required for sampling or minor penetrations. The barrel threading must match the drill and core bits to ensure a secure connection. Users should select barrels and bits with appropriate diamond segment specifications for the material hardness and drilling method. This barrel type is versatile for electric, pneumatic, and hydraulic rigs, so verify the rig's spindle and coupling match the barrel threading and diameter.

Drill Setup Notes

When setting up this core barrel, verify the threaded connections are clean and intact to ensure a solid fit with the drill spindle and diamond bit. Proper alignment and secure threading reduce the risk of barrel loosening during operation. Consider the drilling rig's capacity and fastening options to accommodate the length and weight of the 36" barrel. Ensure water supply for slurry control if wet drilling is planned, as this helps prolong bit life and improves cutting performance. After use, clean concrete slurry and debris from the barrel and bit connection to maintain performance and prepare for the next job.
