CS Unitec 2 1317 0030 Hand Held Hydraulic Underwater Core Drill Product Guide

The CS Unitec 2 1317 0030 is a heavy-duty hydraulic core drill designed specifically for underwater and wet drilling applications in concrete and reinforced concrete structures. This tool addresses the need for precise, efficient core drilling where water exposure or submerged conditions make conventional drilling difficult or impossible.

This handheld hydraulic underwater core drill is commonly used for tasks that require dependable wet diamond drilling to create precision holes through tough materials while submerged. The tool works in conjunction with a supporting drill stand to stabilize drilling operations, making it suitable for underwater construction, repair, and maintenance projects where controlled drilling and slurry management are critical.

Where This Is Used

• Underwater structural inspections and repairs on bridges, dams, or piers
• Diving operations requiring core samples or hole creation below the waterline
• Concrete rehabilitation or installation in submerged environments

Key Details

Selection Notes

From a selection standpoint, it is important to verify that the hydraulic power unit supplying the drill can deliver the specified 6 to 13 gpm flow at recommended pressure for optimal performance. Selecting appropriate diamond core bits for the target concrete and reinforcement type is critical since bits are not included with the drill. The drill stand provides necessary stability—ensure compatibility and sufficient clearance for underwater setups. Hose length and routing should be planned to allow diver mobility and access to the work area without restricting hydraulic fluid flow or causing potential damage to hoses.

Post-Use Care Notes

After underwater use, the drill should be rinsed thoroughly with clean fresh water—not saltwater—to remove salt, slurry, grit, and debris that can impair long-term reliability. Proper flushing of hydraulic lines and cleaning of all connectors supports equipment longevity. Also verify whether an environmentally compatible hydraulic fluid can be used with the power unit to reduce environmental risks in case of leaks during underwater operations. Routine inspection of bit connection points, hose integrity, and drill stand components before and after use ensures safe and dependable operation on subsequent jobs.
