CS Unitec END 130/3.2 PO Electric Core Dril

CS Unitec END 130/3.2 PO Electric Core Dril Product Guide

The CS Unitec END 130/3.2 PO Electric Core Drill is a hand-held, wet drilling tool designed primarily for drilling holes in reinforced concrete, natural stone, and asphalt. It addresses the common job problem of creating precise and clean core holes in tough materials, especially in confined or narrow spaces where larger equipment cannot maneuver effectively.

In practical rental and jobsite use, this electric core drill is often selected for jobs that require versatility between hand-held and rig-mounted drilling. It provides adjustable speed through a mechanical 3-speed oil bath gearbox, allowing operators to match drill speed to core bit diameter and material hardness. Its wet drilling method helps reduce dust and cool the bit, which is essential when working with concrete and other abrasive surfaces. The built-in leveling bubble and slip clutch improve drilling accuracy and protect the motor from overload during extended use.

Where This Is Used

• Concrete coring for plumbing, HVAC, and electrical penetrations in building construction
• Sanitary, heating, and ventilation system installations requiring precision holes
• Civil engineering applications including roadworks and landscape construction

Key Details

Selection Notes

From a selection standpoint, the deciding factor is often the required hole diameter and access conditions. For holes up to 3-1/4" diameter in tight spaces, the hand-held mode offers greater mobility and control. For larger diameters up to 6", rig mounting ensures stability and drilling precision. The adjustable 3-speed gearbox lets the operator set speeds to match bit diameter and material hardness, reducing wear and optimizing drilling efficiency. Confirm that your site can provide a reliable 110V power source with GFCI protection and a suitable water supply for bit cooling and dust suppression. The integrated overload protection features, such as the slip clutch and temperature indicator, help avoid motor damage during tough or prolonged drilling conditions.

Drill Setup Notes

Plan for hose routing to and from the water supply to maintain consistent wet drilling flows. Verify the compatibility of core bits with the drill’s thread sizes before starting work. The built-in leveling bubble assists in maintaining perpendicular holes, improving accuracy in critical construction penetrations. After use, clean concrete slurry and debris from the drill and check all hose and electrical connections. Inspect the overload indicator and motor brushes periodically to ensure the motor remains protected during operation. When using the rig-mounted setup, ensure the stand or frame is securely anchored to maintain drilling stability on uneven surfaces.
