Hammer Drill Dedra DED7837 — corded 1500W, hammer and drill modes, auxiliary handle

The Dedra DED7837 corded hammer drill delivers 1500W of input power for drilling and light chiselling in concrete, masonry and metal. Equipped with combined hammer and drill modes and a variable-speed control, this tool is engineered for sustained performance during construction, renovation and DIY tasks. An auxiliary handle provides additional control and stability for precise drilling and impact work.

Advantages

The drill’s 1500W motor ensures consistent torque and power under load, allowing efficient penetration in dense materials. Switchable hammer and drill modes give flexibility for both impact and non-impact tasks, while the variable-speed trigger enables accurate control over drilling speed. The auxiliary handle improves handling and reduces user fatigue by offering a secure grip and better torque management. The corded design provides continuous power for extended work sessions without battery interruptions.

Suitable for

• Drilling holes in concrete, block and brick
• Light chiselling and demolition work
• Metal and wood drilling where higher power is required
• Construction and renovation projects requiring continuous operation
• DIY and home improvement tasks demanding reliable impact action

Key specifications

• Handle: auxiliary adjustable side handle for improved control
• Power source: mains (corded)

How to use

Before use, inspect the power cable and tool body for damage and select the appropriate drill bit or chisel for the material. Secure the workpiece and fit the chosen bit into the chuck, tightening it according to the tool’s specifications. Choose the required operating mode — hammer for masonry and concrete, drill for wood and metal — and set the speed using the variable trigger to match the material and bit size. Maintain a firm two-handed grip using the main and auxiliary handles, apply steady pressure without forcing the bit, and allow the tool to do the work. After finishing, switch off and unplug the tool before changing accessories or performing maintenance.

Recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling or chiselling. For extended use, take regular breaks to minimize fatigue and monitor bit condition to ensure clean cutting and safe operation. Avoid using the tool in wet conditions and ensure the mains supply matches the voltage rating. For best results in concrete and masonry, start with a smaller pilot hole and then increase to the desired diameter.
