Concrete Core Drill Dedra DED7615, 1700 W, max drilling Ø 130 mm

Concrete core drill Dedra DED7615 is a corded electric tool with a 1700 W motor designed for drilling large-diameter holes in concrete and masonry. It is suitable for creating openings for pipes, conduits, anchors and ventilation outlets where stable, continuous power and compatibility with standard core bits are required. The tool is built to handle demanding site conditions and to produce precise circular holes up to a maximum diameter of 130 mm when used with appropriate core bits and mounting accessories.

Advantages

The Dedra DED7615 combines a high-power 1700 W motor with a robust mechanical design to deliver steady drilling performance in hard materials. Its capacity to accept core bits up to 130 mm diameter allows efficient creation of large openings without repeated chiseling. The design emphasizes stable operation and compatibility with commonly used core bit shanks and drill mounts, enabling integration with typical jobsite rigs and stands. The tool’s power and build quality support continuous operation under typical professional and advanced DIY use.

Suitable for

• Drilling circular holes for plumbing pipes and conduit installations
• Making openings for ventilation outlets and ducting
• Installing anchors, sleeve sleeves or recessed fixtures in concrete or masonry
• Preparation work for retrofit and renovation projects in buildings

Key specifications

• Rated power: 1700 W
• Maximum drilling diameter: 130 mm (with compatible core bits)
• Intended material: concrete and masonry
• Power supply: mains corded electric
• Design: for use with standard core bits and mounting accessories

How to use

Fit a compatible core bit with the correct shank type and ensure secure attachment according to the bit and tool instructions. Mount the drill on a suitable rig, stand, or guide to maintain alignment, and secure the workpiece or position to prevent movement. Start drilling at low speed to establish the pilot contact, then apply steady feed pressure and use appropriate cooling or flushing if the chosen core bit and material require it. Maintain stable supply voltage and avoid excessive side force; withdraw the core bit periodically to clear debris when drilling deep holes. Disconnect power before changing bits or performing maintenance.

Usage recommendations

For best results, use diamond-tipped or carbide-tipped core bits rated for concrete, verify shank compatibility before operation, and use a drill stand or rig to ensure perpendicularity and safety when drilling near structural elements.
