CS Unitec 2 1333 0010 Pneumatic 2.1hp Core Drill With Anchor Stand (U/W) Product Guide

The CS Unitec 2 1333 0010 SA is a pneumatic diamond core drill designed to precisely bore holes up to 6 inches in diameter in concrete, reinforced concrete, masonry, and refractory brick. It addresses the challenge of controlled, safe drilling in hazardous environments where electric tools are unsuitable. The tool’s pneumatic power system produces 2.1 horsepower with adjustable speeds, enabling efficient drilling with better control across varying materials.

This drill is commonly used in industrial, petrochemical, and construction environments for structural anchoring, plumbing, electrical, and HVAC core drilling tasks. Its pneumatic operation makes it safe for use in explosive zones and other hazardous conditions. The inclusion of an anchor stand enhances drill stability and accuracy for larger diameter holes and longer drill times, though it can also be used hand-held when necessary. The three-speed gearbox (400, 900, and 1600 RPM) allows adjusting the drilling speed to optimize performance depending on core bit size and material hardness.

Where This Is Used

• Industrial and petrochemical sites requiring non-electric explosion-safe tools
• Construction sites involving concrete and reinforced concrete drilling
• Applications requiring precise structural anchoring and installations
• HVAC, plumbing, and electrical core drilling where controlled hole size is critical
• Underwater or wet environments with appropriate post-use care

Key Details

Selection Notes

When selecting this pneumatic core drill, verify compressor capacity to ensure it can consistently deliver 77 CFM at 90 PSI with minimal pressure drops. Confirm air-line size, length, and routing to avoid restrictions or kinks that could reduce airflow. Moisture control in the air supply is essential to prevent internal corrosion and maintain performance. The anchor stand should be considered for jobs requiring greater precision or extended drilling time, supporting rig-mounted use and stable positioning. For underwater or wet environments, confirm operator or diver access and plan air-line routing to avoid abrasion or flow restrictions. Bit selection should align with the material hardness and desired hole diameter, using compatible 1-1/4"-7 UNC or 5/8"-11 UNC core bit connections. The 3-speed gearbox provides flexibility to optimize drilling speed, so choose the speed based on bit size and material conditions to balance cutting rate and tool lifespan.

Post-Use Care Notes

After underwater or wet use, thoroughly rinse the drill with clean fresh water to remove salt, grit, slurry, and debris. The pneumatic motor should be flushed with lightweight oil after each use to displace any accumulated water and help prevent corrosion. For topside use, clean off slurry and dust and inspect bit connections, air-line couplers, and anchor stand components before the next job to maintain reliable operation. Proper cleaning and maintenance extend tool service life and ensure consistent drilling performance.
