CS Unitec 2 1317 0030 SA Hydraulic Underwater Core Drill Rig Product Guide

The CS Unitec 2 1317 0030 SA is a hydraulic underwater core drilling rig designed to efficiently drill through concrete and reinforced concrete in submerged environments. This tool addresses the challenge of underwater coring where conventional drills cannot operate effectively, providing a specialized solution for heavy-duty wet diamond drilling applications.

Commonly used in underwater construction, maintenance, and repair projects, this core drill rig is operated with hydraulic power, routed from a compatible hydraulic power unit. It is typically employed by professionals who need to perform precise wet drilling operations underwater, such as in marine construction, bridge pier repairs, or underwater foundation installations. The hydraulic system supports the continuous wet drilling process by delivering and recycling hydraulic fluid to maintain tool performance and longevity.

Where This Is Used

• Underwater concrete and reinforced concrete drilling
• Marine construction projects requiring submerged coring
• Bridge pier and underwater foundation repairs

Key Details

Selection Notes

When selecting this underwater hydraulic core drill rig, verify that the hydraulic power unit available at the job site can provide the recommended oil flow of 6 gpm and accommodate up to 13 gpm of return flow. Confirm the hose lengths and the routing plan to ensure that operators or divers can access the drill point without interference or restricted flow. Consider the size and type of diamond core bits needed for concrete and reinforced concrete to match the drill rig's capacity and mounting setup. Planning for water and slurry management around the work point is important to maintain drilling efficiency and clear visibility underwater. Also, check whether the hydraulic power unit fluid is compatible with environmentally preferred hydraulic oils if the project site includes sensitive water conditions.

Underwater Setup Notes

For underwater drilling, ensure that hydraulic hoses are routed safely to prevent damage from abrasion or kinks and allow sufficient diver mobility and access. After each underwater use, rinse the drill thoroughly with clean fresh water to remove any salt, grit, slurry, or debris that may impair performance and longevity. This rinsing should not replace scheduled manufacturer maintenance but supports tool reliability for subsequent jobs. Additionally, plan for proper slurry and water circulation around the drill to avoid sediment buildup that can obscure visibility or complicate coring accuracy.
