Rotary Hammer DeWALT D25430K-QS

The DeWALT D25430K-QS rotary hammer is a corded, SDS-plus tool designed for drilling and chiselling in concrete and masonry. With a 1000 W input and a robust large hammer mechanism, it targets professional and serious DIY applications where power and durability are required. The tool weighs 4 kg and includes active vibration control with a floating back handle for reduced vibration and improved operator comfort, plus an electronic variable speed switch for precise control during different drilling and chiselling tasks.

Advantages

The active vibration control system with a floating back handle reduces transmitted vibration, allowing longer working periods with less fatigue. The electronic variable speed switch provides accurate speed regulation for controlled starts and material-appropriate cutting or chiselling. A large hammer mechanism construction enhances durability and supports consistent performance under heavy use, while the 1000 W motor delivers sufficient power for demanding concrete and masonry operations.

Suitable for

• Drilling holes in reinforced concrete and masonry
• Chiselling and light demolition work in concrete and brick
• Installing anchors, rebar plugs and through-fixings
• Professional construction, renovation and heavy DIY projects

Key specifications

• Power input: 1000 W
• Tool type: Rotary hammer, SDS-plus
• Weight: 4 kg
• Vibration control: Active system with floating back handle
• Speed control: Electronic variable speed switch
• Mechanism: Large hammer mechanism for extended life and performance

How to use

Select the appropriate SDS-plus bit and ensure it is correctly seated in the chuck. Choose the required mode (drill, hammer drill or chisel) and set the electronic speed according to the material and bit diameter. Position the tool perpendicular to the working surface, apply steady pressure and allow the hammer mechanism to do the work. Use intermittent operation when drilling deep holes to clear dust and avoid overheating. For chiselling, secure the workpiece and use controlled movements; switch to lower speeds when more precision is needed.

Usage recommendations

For safer and more effective results, wear appropriate personal protective equipment including eye protection, hearing protection and dust mask. Use the tool with compatible SDS-plus accessories and maintain the ventilation slots clear. For prolonged jobs, take regular breaks and check the tool for wear or damage; follow manufacturer maintenance guidance for lubrication and service intervals.
