CS Unitec 2 2404 0030 Underwater 1" Air Hammer Drill (ATEX)

CS Unitec 2 2404 0030 Underwater 1" Air Hammer Drill (ATEX) Product Guide

The CS Unitec 2 2404 0030 is a pneumatic air hammer drill designed for underwater and hazardous atmospheres where electrical tools pose spark or ignition risks. It solves the challenge of safely and effectively drilling in concrete, brick, and masonry in wet or explosive-rated environments by using compressed air power and percussion drilling action combined with a water flushing system.

This type of pneumatic hammer drill is commonly used in industries that require drilling under demanding environmental and safety conditions, including underwater maintenance, chemical plants, refineries, and heavy construction near hazardous atmospheres. The included water flushing attachment helps suppress sparks and dust at the drill bit, preserving visibility and minimizing ignition potential. Pneumatic operation makes it suitable for wet or submerged applications where electric tools are not allowed.

Where This Is Used

• Underwater drilling and maintenance in marine, subsea, or wet industrial environments
• Hazardous or explosive atmospheres requiring ATEX-certified pneumatic tools
• Drilling concrete, brick, block, and masonry in chemical plants, refineries, and utility sites
• Heavy industry jobsites where pneumatic tools are preferred for safety and performance
• Applications requiring the use of SDS-Plus carbide-tipped bits up to 1 inch solid or 3 inch core bits

Key Details

Selection Notes

From a selection standpoint, confirm that the air compressor can supply consistent pressure and adequate volume to maintain hammer drill performance, especially underwater where hose length impacts air flow. Ensure the air-line is routed to prevent kinking and abrasion, with moisture filtration to avoid damage to the pneumatic motor. The ATEX approval is essential when working in hazardous atmospheres to reduce ignition risk. Bit choice should suit the material: SDS-Plus carbide-tipped bits up to 1" diameter for solid holes and up to 3" diameter for core drilling in brick or block.

In underwater or wet use, access and visibility at the drilling point should be considered; the water flushing attachment doubles to suppress dust and sparks. Plan hose and water-flush tubing routing to avoid interference with diver or operator movements. Confirm the availability of clean fresh water for flushing and post-use cleaning.

Post-Use Care Notes

After underwater or wet operation, thoroughly clean and rinse the drill with clean fresh water to remove salt, grit, and slurry residues. Additionally, the pneumatic motor should be flushed with lightweight oil after each use to displace any accumulated water internally. This routine supports drill reliability and longevity but does not replace scheduled manufacturer maintenance.
