CS Unitec 2 1333 0010 2.1hp Core Drill (U/W)

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

The CS Unitec 2 1333 0010 is a pneumatic core drill designed to cut precise holes in concrete, reinforced concrete, masonry, and refractory brick. It addresses the common jobsite challenge of safely and efficiently drilling cores in tough materials and hazardous environments where electric tools are not suitable.

This core drill is often used in construction, industrial maintenance, and marine industries for creating clean, controlled openings. Its pneumatic motor allows operation in confined and potentially explosive environments. The tool can be operated either handheld or rig-mounted, adjusting drilling capacity and control depending on the application, which offers flexibility in varied rental projects.

Where This Is Used

• Heavy construction sites requiring core holes in concrete or reinforced concrete
• Hazardous environments such as petrochemical plants or confined spaces with risk of explosive gases
• Marine and underwater applications where pneumatic tools reduce electric hazard concerns

Key Details

Selection Notes

From a selection standpoint, confirming air supply capacity and pressure is critical to maintain expected drill performance. The drill consumes 77 CFM at 90 PSI, so adequate compressor sizing and moisture control in the air line are necessary to avoid performance loss or equipment wear. For underwater or marine use, ensure appropriate air-line routing that facilitates diver or operator access while preventing hose kinks or abrasion. The maximum drilling diameter is up to 6 inches with a drill stand and up to 3 inches handheld, so plan bit size accordingly to match your project requirements and mounting options.

The mechanical safety slip clutch adds protection during tough drilling conditions but remember to inspect clutch and gear components regularly. The 360° rotatable handle improves control and positioning flexibility, especially in confined or awkward spaces.

Post-Use Care Notes

After underwater or wet use, thoroughly rinse the drill with clean fresh water to remove salt, grit, slurry, and debris. Additionally, flush the pneumatic motor with lightweight oil after each use to displace accumulated water inside the motor housing. This helps support reliability and extends service life but does not replace routine manufacturer maintenance. For topside use, clean slurry and dust from the drill, check spindle connections, water swivel, and airline fittings before the next job.
